Artificial analysis shows this: underperforming Qwen3.8 Flash Next and GLM 5.3 Flash, both of which you can run on a single B300 . I think Meta has a bit of catching up to do in the open-weight space.
As an aside, it's really unfortunate that artificial analysis only provides comparison at the highest reasoning level, which is mostly unusable for high-volume production use cases. I would really like them to start providing comparisons at low and medium reasoning levels across these models because those tend to be the ones that actually get used in production.
Been using GLM 5.3 Flash via Ollama Cloud basic subscription:
if this is the only model I had to use for the rest of my life, I would be cool with that. It's good at a wide variety of tasks including reverse engineering, design, working with ESP 32 etc.
I think Muse Spark 1.3 is better but GLM 5.3 Flash is an excellent daily driver.
I've been using GLM 5.3 Flash as the planner and DS 4.1 as the task worker over the last month and the results have been very good, predictable, ridiculously cheap.
V4 isn't the newest DeepSeek, and GLM 5.3 non-Flash isn't the same ballpark
- DeepSeek V4.1 Flash has marginally better coding, and smaller experts (8B-In/16B-Out) with more compressed attention and KV cache, so it's faster but will have less expertise per task. It's a 552B model, so while it theoretically may contain more trained data it also requires more RAM (the experts are smaller to compensate for speed loss) making it harder to serve without the distributed KV cache DeepSeek hosts.
- GLM 5.3 Flash has marginally better agentic work, and has video input (DS doesn't), and its experts are 18B so there's more intelligence per task. It's a 320B model so it requires less RAM which will make it cheaper to serve. Considering it's a much smaller model, the higher intelligence indicates their architecture/training is better.
- GLM 5.3 (non-Flash) is far more intelligent than both; it's a 744B model with 40B experts, but it's text-only.
You don't need to directly compare the same reasoning levels. Today you can compare Sol on Low vs Haiku on Max, for example, but you can't look at GLM 5.3 High, only Max.
For some tasks I genuinely feel Opus 5.5 does better on low than medium or high. The trouble, as always, is figuring out which.
Edit: I realize after commenting that you're not suggesting medium is useless, but just arbitrary and differs between models. Personally I don't want to directly compare mediums between models, I just want to be able to compare across effort levels.
i run opus on medium, sonet on high, and haiku on high for implementation based how complicated is
for planing and specing and review opus is on high usually, except if if the task is contained.
did not try to run it on low, will have to try it.
It shows the time to complete a task versus intelligence index, which is much more important for my use-case as I do quick back and forths usually. Someone on here suggested it to me a while ago. It also captures speed and token efficiency nicely, since both of these decrease time per task.
this is properly bad as you can run glm on 6000pro, at (in my eyes) pretty good quant, and a q2 on a 5090. im suprised at how good 5.3 flash is at some parts. i still think ds4.1 flash is better but it is more demanding. i hope meta pushes something in a range of 300-400b with a 15-20b active parameters. i know its a crowded space. but it would be fast and probably mostly good enough.
Yep, just benchmarked it against GLM5.3 Flash on my own local bench and it's slower in TTFT, tok/s and concurrency. It also scored lower.
Tried different reasoning levels and didn't really see any difference but GLM 5.3 flash only really works high, max or none so I couldn't really compare the lower efforts which appear to work on Spark.
My immediate reaction is that it’s weaker on coding than other open-weight models and that coding is a primary use case for running locally (not the only one, but surely a major one). That said, it takes a lot to get full Kimi and GLM running locally.

The frustrating thing is they started doing this for the big labs—you can see their benchmarks for all reasoning levels of Sol 6.1 or Haiku 5.5. They just don't seem to do it for any of the open weight models.
very true. when configuring custom agents for enterprise, we almost always default to none or low reasoning knobs. The added latency from medium or higher reasoning levels compared to the improvement in response quality is a diminished return.
Since there are many comments here arguing that this is not open weight, I looked at the license. Basically, you're free to use this except this clause:
> If the Licensee or any of its affiliates provide a third party with access to artificial intelligence models as a product or service, via API or a similar interface, where the third party receives outputs of such models (“Model as a Service”), and the aggregate gross revenue of the Licensee and its affiliates exceeds twenty (20) million US dollars (or the equivalent in other currencies) during any consecutive twelve (12) month period, the Licensee must notify Meta and enter into a separate written agreement with Meta before offering the Software or any Derivatives as part of that Model as a Service business. This Section 3 does not apply to (a) internal use, research, or any commercial activity that is not Model as a Service, or (b) the Licensee's use of the Software as a component to power features of the Licensee's own product or service that is not a Model as a Service.
They're allowing the use of this in commercial products, just not selling the model directly.
Still not an open-source license. Means no restrictions on "fields of endeavor", a.k.a. the free software definition's "freedom 0": the freedom to run the software for any purpose.
I'm sick to death of these shameless dilutions (including the notion that open-weight is open-source; the OSI is totally captured at this point)
Open-weights means weights are released under an open-source license.
I would, contra the OSI, not consider the model to be open-source even if the weights were under an open-source license. But that is the minimum condition under which it could be considered open-weight.
> Publishing these values allows others to download and use the model, while permission to modify, fine-tune or redistribute it depends on its license.
Those restrictions are definitely not compatible with the definition of open-source/FOSS. I think you have a much stricter view of what open-weights means than the industry.
"Open weights" is a correction that arose out of calling models whose weights were released under open-source licenses "open-source" before the OSI sold out. These companies trying to dilute the polite correction just like they tried to dilute "open-source" only reinforces my point.
There was an attempt to create an analogue of the OSI's Open-Source Definition that acknowledged the problems of merely releasing weights as "open-source". That project seems to have largely failed or fizzled, and "open weight" has come to be used mostly as a way of acknowledging that only the weights have been released under open-source terms.
This model of Meta's fails even that dramatically weakened standard.
This is just a series of dilutions by which giant corporations are trying (and apparently succeeding here on "hacker" news) to trade on the cachet of commitments they don't actually hold.
I think it is a fair license. It’s a bit of “Open”-washing but reasonable to the model trainer for their investment and to the public for having more base model options with novel architecture.
Also, IANAL, but under U.S. copyright law, the weights of machine learning models are excluded from copyright as they are the product of an automated optimization process (e.g., stochastic gradient descent, expectation maximization, genetic algorithms) rather than human authorship. Granted, this has yet to be fully tested in court and going to court is expensive, so it's likely that your employer would prefer to err on the side of caution and respect such attempts at model licensing anyway, similar to how one might treat a ToS agreement. Nonetheless, this was partially tested last year in Thaler v. Perlmutter which affirmed that copyright requires human authorship, reading the Copyright Act's provisions on ownership, duration, and transferability as presupposing a human author[1].
If you want to assess the position of the U.S. Copyright Office for yourself, the relevant text can be found in the Compendium of U.S. Copyright Office Practices § 313.2, "Works That Lack Human Authorship"[2], which states:
> […] the Copyright Act protects “original works of authorship.” 17 U.S.C. § 102(a) (emphasis added). To qualify as a work of “authorship” a work must be created by a human being. See Burrow-Giles Lithographic Co., 111 U.S. at 58. Works that do not satisfy this requirement are not copyrightable.
> […] the Office will not register works produced by a machine or mere mechanical process that operates randomly or automatically without any creative input or intervention from a human author. The crucial question is “whether the ‘work’ is basically one of human authorship, with the computer [or other device] merely being an assisting instrument, or whether the traditional elements of authorship in the work (literary, artistic, or musical expression or elements of selection, arrangement, etc.) were actually conceived and executed not by man but by a machine.” U.S. COPYRIGHT OFFICE, REPORT TO THE LIBRARIAN OF CONGRESS BY THE REGISTER OF COPYRIGHTS 5 (1965).
Oh, and there's also a bit in the following Section 313.3, "Works That Do Not Constitute Copyrightable Subject Matter"[2], which explicitly excludes mathematical principles, formulas, algorithms, and equations, along with DNA sequences and other genetic or chemical compounds, regardless of whether they are produced by humans or by nature. If one takes the perspective that machine learning models are algorithms, the conclusions on copyrightability are pretty clear.
If the weights were produced by a purely mechanical process without any input, then I would be more inclined to believe the distinction there is significant. But as the optimization processes you've mentioned are merely tools that operate with a dataset, the provenance of that dataset becomes a factor towards copyright.
> Granted, this has yet to be fully tested in court and going to court is expensive, so it's likely that your employer would prefer to err on the side of caution and respect such attempts at model licensing anyway, similar to how one might treat a ToS agreement.
You may be conflating 2 things - the Muse model weights themselves, and what the models output when run. The former is prima facie the product of human authorship and hence has full protection of copyright law, the latter fits your characterization of likely not having copyright coverage. Meta can use the copyright on the model weights to dictate licensing terms. IANAL too.
They are not facts. They are numbers or bits on a medium, and software bits have been copyrighted for so long, there were 5¼" floppies with "(c) 1977" printed on them.
Even if your revenue exceeds 20MM you can still use this model from inside a commercial product but you can't expose it directly as a "model as a service"
Yup, I rather meant to point out that even if all you want to do is sell access to the model on your hardware, you can _still_ do so up until a non-trivial scale.
day one support for all inference engines so that whichever kind of capable computer you have, you can run it.
you do need a really capable computer though
They suggest a pair of Mac Studios w/ M5 Ultra chips and 512 GB of RAM. A single Mac Studio w/ M5 Ultra and half that RAM (256 GB) is around $11k, and the 512 GB option isn't even available yet. So.... yeah.
Yes, but still, what about users looking for NPU support. What happened to Microsoft's copilot+ PC campaign? (the NPU hardware, not the logo key and ad campaign)
AMD's XDNA2 NPU is best supported by ONNX, I think Qualcomm Hexagon is too. The best consumer unified architectures are Apple, AMD ai+ and Qualcomm Snapdragon X Elite, even intel has an NPU offering.
NPUs are meant for tiny, tiny models that can run basically at all times but cannot affect battery life (e.g. translation, live-video cleanup, filesearch etc.), not for big LLMs. This is about 500 times to large for a NPU.
There are plenty of smaller less powerful open weights models if all you have to run it on is an NPU.
This is a much larger more powerful model, so running it locally will not be for everyone, but you can still run it via a hosting service such as Fireworks AI.
Like I said last week. I think zucks original llama thesis is proving more correct by the week. The rent market on intelligence never materialized, if you have THE frontier model, you can charge rent (for a few weeks, maybe month). But after a certain capability level it's price that drives the decision.
Zuck is doing the thing he's really good at, and building a moat around the network (Muse is VERY sticky), and now that we're all going to standardize on Meta's model, we're going to optimize the heck out of the infra to run the model making it cheaper for him to scale, thus bringing in more participants to his network, and thus making his network more valuable.
Google, Apple, and Microsoft are each in a stronger position to win consumer AI because they're guardians over the foundations of the user's experience. Meta always has to wonder whether they're going to be edged out, like when Apple decided to limit permissions or set new rules on user data handling.
How has Meta responded? With a failed phone and speculative headset.
That's entirely why Zuck's been pushing VR and the metaverse for so long. they have no OS to control - Microsoft has desktop, Apple has their vertically integrated devices, Google has both Android and also Chrome.
Meta is at the whims of these other companies to play nice - and they already got hit hard once by apple when they decided to anonimize add profiles on the iphone and go privacy first.
Okay, so I've heard Apple "prioritized their own ads". If there's meat behind that - cool (and perhaps might not do anything about certain scummy listings on the app store)
But app stores and iOS ostensibly exist exactly so Zuckerberg can't do what he does, which is steal credentials. Facebook syncs everything, bought Whatsapp to do the same; of course he's pissed off his ill-gotten moat got attacked
Apple didn’t figure out yet that Google’s AI performance is nothing like Google search. Google’s AI is just junk, worse than open Chinese models. If someone (Facebook,OpenAI) gets a hold on the “killer” app, Apple won’t be able to do anything to truly compete. They will be late and end up with a social network like “find my friends” or whatever that useless thing was that nobody used.
Muse, the pi/openclaw/AI assistant app is maybe not impressive to HN, because you can always just "get an FTP account", as it were, but if you're outside of the HN bubble and don't hate Facebook, Muse is an absolute winner. It's currently the top downloaded app on iOS, above ChatGPT, TikTok, and Claude. I think they've currently got the strongest consumer AI play but we'll have to wait and see how the situation evolves.
>Google, Apple, and Microsoft are each in a stronger position to win consumer AI because they're guardians over the foundations of the user's experience.
From everything I've seen, they're all too large and dysfunctional to make a competent play in consumer AI. Anyone in there trying to work on it is too far removed from end product and is answering to too many masters.
>Google, Apple, and Microsoft are each in a stronger position to win consumer AI
Microsoft has completely lost the ability to make good software; see Microsoft Teams and what they've done to Windows 11. Apple don't have a foundation models team so they're limited to using other people's models, which handicaps them as they can't do vertical integration like with their other products. Google hasn't made a single competitive consumer product in the past decade, but has certainly killed a few.
"Microsoft has completely lost the ability to make good software; see Microsoft Teams and what they've done to Windows 11."
Uh, what is your positive comparison point?
I have been using MS apps since MS-DOS 6.0 and Windows 3.1 (including doozies like Windows Millennium and Vista) and Teams and W11 are some of most stable, "it just works" pieces of software coming from them I can think of...
> Microsoft has completely lost the ability to make good software
did they ever? maybe MS DOS, Win 3.1, and Win2000 were ok, although PC DOS and OS/2 were better; Sure what an unusable junk it's today is beyond any precedent in history, but why many companies use it today at all? why?
If you’re falling for “sticky” interfaces, you’re not going make it. Your competitor won’t have the stickiness and the ability to use any harness and that will overcome Muse in the long-run. Let’s not forget, Muse is a close to SOTA model right now, but so was Google, and now they’re irrelevant. Google is one of many funded models that were close to SOTA, but we realized it’s benchmaxxed.
People are going to say that it doesn’t matter if you’re the best. If Muse, Grokbot, and Dot are able to reach mass appeal, it doesn’t matter if a person using a custom harness is better.
I respectfully disagree. There is a big difference between someone that’s running a custom harness that’s almost like a personal OS versus someone using something out of the box. And if you’re for using this to run your business, think for yourself who’s going to win, the person customizing everything or the one using what the big corps give you.
These are good points, though OP did specifically say that Meta is going to win "consumer" AI. I don't think the average consumer of AI is going to ever have to think about harnesses or worry about SOTA, they really will continue to interact with whatever is stickiest.
This exactly. The "harness" for consumer is not well defined but likely quite sticky if someone can build one. Meta is better positioned with its reach of whatsapp etc unlike anyone to try this.
Meta being meta, will likely run this as an "experiment mode" for 6 months to an year and if it does not work scrap it all and move onto the next thing.
There is a risk ofc muse does not work. But there is a good chance that with the ridiculous number of product teams doing A/B testing with insane number of people already on it, something will emerge that is interesting in a way it never could for their erstwhile Ar/VR foray.
The field is changing weekly at this point. Meta, OpenAI, and Anthropic have the most distribution right now so any can take this spot.
So why would you lock yourself in? They want you to lock yourself in, but if you build your own system, you won’t be. A layman will just use what’s best and get himself locked in, but they might be using an inferior model.
AI is a force multiplier. Doing the right thing with the right expertise is yielding dividends.
Many people don't even know what locking in means. The crowd in this forum < 1% of the world do, you and I do, and maybe a few outside. There are only laymen outside of 99%. No one i know of knows or uses a harness. They don't know the large number of VMs built on say Hermes. They really don't care or have time. If you give them a ready made product thats a click away, and its good enough, they will use it.
But this is what I’m saying, consumer AI is forever changing. Investing your time and money into a closed harness will put you behind someone running their own system that’s model agnostic.
If you’re on a forum like HN, would you realisticly invest your time and widgets into a closed harness instead of building your own? What if Meta’s model falls behind and all your things are on there? My advice is to invest in building your own because no one lab has shown they are worth using.
As far as “consumer,” I’m simply comparing consumer AI to a custom built one. One of OpenAI, Anthropic, Meta will probably win since they have the most distribution.
>For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software.
And, "stickiest", mind, where most are allready soul-sucked into the neverending doomscrolling dopamine nightmare that is Zuckbook - to beging with.-
First they "captured", or moated "communication". Now, they are going to capture "utility" ("I am actually doing something useful, not just doomscrolling. I can spend an extra 8h here. It feels good").-
I’m talking from experience. I’m run a software factory building open source alternatives and Argon is the worst model. Wrecked multiple codebases. But every use case is different. If you’ve found success in yours, use it.
> And if you’re for using this to run your business, think for yourself who’s going to win...
That's not consumer AI though. The whole "vs out of the box" is pretty much the definition of consumer AI. People don't want to fiddle with things. That's why UX matters. SOTA only matters in consumer if it translates to the UX. And no one has landed that yet. Many are working on it.
Seriously. Muse hasn't even been around long enough to determine if it is "sticky" in any meaningful way, let alone in the context of competing against frontier models from competitors.
And based on what I'm seeing, it's far from even being in that category as a service yet. Seems like the OP is conflating seeing a bunch of Muse ads on Facebook with its presence as a competing frontier model.
The ads strike me as basically deceptive. Like when I was in NYC last week the ads showing a cuddly mascot were all over the place. Video ads on YouTube don’t show a Bay Area TurboKnerd geeking out with a top-of-the-line Mac mini to a reskinned OpenClaw (reality) but rather some guy running and talking to his phone to schedule a massage.
I like the image of Muse and think a product that delivers what it promises to the consumer could be a hit but,,, this looks like something they rolled out in a hurry to take advantage of the FOMO of the uninformed and boost their stock price for a few months until reality catches up. They are a huge company and they could do something only a big company could do but no…
Like the real mass market product is not going to be a smart shell for a Mac it’s going to be cloud based. Like is it economic for your Mac to be sitting there running all the time when you are using 10%? The true believer say yes, the mass market says no. Is Apple going to let them put a skin on your Mac or is this a product that Apple will embrace and extinguish?
The naming is a bit confusing, but there are two things called Muse ...
There are the models, such as Muse Spark, Muse Wonder, and this Muse Open.
There there is "Muse" itself which is a cloud based "personal agent", always running in your own cloud-based virtual machine, that you can assign tasks to.
I think the Muse agent (which competes with Instinct, Grok Bot, etc) is where Meta currently believe the money will be. While you can pay for higher usage levels, it seems they are expecting many people to use the free tier, and they will make money by charging transaction fees to services Muse uses/orders (e.g. travel, entertainment) on your behalf. This "personal agent" market is predicted (but let's see) to be huge - much larger than the coding agent market.
I assume the guy in the ad is talking to his Muse agent to schedule the massage.
I disagree with the claim that its sticky, but this is the wrong response. Reductive and doesn't take into account the obvious things (UX, network effects, barrier to entry to use the product). All 3 of these are much better with Muse than they with are similar products.
definitely not me; I wouldn't doubt if Zster is working on turning muse into sleeper agents, _assuming_ chinese models will do the same, so they crib data and send it home like a good little maleware model.
In fact, we're going to see an explosion of the worst kind of AI model thanks to thinks mr Z thinks is in his best interest.
Remember, they had reports going back more than a decade about how they're harming children and destabilizing entire countries and as soon as Trumps in the whitehouse, they're licking boot.
I think any personal AI agent at this point is "very sticky", not just Muse. You really aren't going to switch when a lot of the value is in the agent memory and there's no easy way to export that, similarly to how you aren't going to switch away from Spotify when it's learned all your song preferences which you can't export. Right now, maybe the agent memory is small enough that if you ask the agent to export you'll get most of it out (Claude has notably made official export instructions to encourage switching from ChatGPT in the past), but in the future the memory will be too large and complex to do that effectively, and platforms could also block the memory export or degrade it deliberately.
So, in the long run you pretty much have to pick one personal agent and stick with it, and switching is costly (unless you are using an open agent that lets you just download the memory, in which case it actually becomes cheap, because AI agents make other parts of switching way easier in general). For the purposes of Meta this means whatever user they get they'll probably keep.
HOWEVER, the thing that Muse doesn't have is network effects. They're running into the exact same problem as ChatGPT in this area, IMO. There's no reason for you to be running specifically Muse even if all of your friends are running it. So that gives other vendors a chance to catch up.
You can export all your data from OpenAI and Anthropic. I also exported all of my Liked songs on Spotify and have a scheduled task to pull any new ones each day.
Also honestly, the models don't have to get much smarter to handle the consumer side of things. They could innovate a ton on the harness to farm out requests and manage the state of the agent. They have an incentive to do this to reduce the infra usage so they can go wider with the agent.
I'm looking forward to seeing Muse devices like Amazon's devices but with superintelligence:
- Muse-equivalent of Alexa
- Muse-equivalent of Ring security devices: doorbells, cameras, alarms, etc
- Muse home automation devices (lights on/off, smart roller, smoke detector, water detecto, etc)
- Muse ring
...
Sure, just not nearly enough for sustainability I think. I'd reserve that call for the moment we can stop bathing in free VC money by using subscriptions.
Also, as far as my own use goes, I found that the capabilities/price ratio of DeepSeek's offering is very hard to beat. It's really good enough so the thing that matters to me (besides table stakes like uptime, latency, etc.) is price at this point.
Of course they are “profitable”, Dario said so last month (if you accept a definition of “profitability” under which every tech startup is profitable by the day they have their first paying customer).
They seem to be reporting gross margin by excluding the cut that cloud providers take for hosting their models, and excluding R&D.
Basically they seem to be taking credit for the whole amount that customers are paying cloud providers to run Anthropic models, rather than the actual net proceeds of that business to Anthropic.
> They seem to be reporting gross margin by excluding the cut that cloud providers take for hosting their models, and excluding R&D
The media is overstating what they're being leaked.
Anthropic is reporting traditional losses. It's also highlighting that operating figure, because it answers the question around what the business could look like in a steady-state and first-party-only mode.
They aren't claiming the profitable right now. But for an unprofitable company, having these sorts of metrics can give you a sense around when they will become profitable and what it will take. (Plenty of people were doubting that AI makes money on inference not too long ago.)
How about the fact that they're not shouting from the rooftops how they're managing to make money in an industry that is currently mostly known as a giant money fire? Instead they're reporting being profitable "after making certain adjustments", which sounds a lot like "not profitable".
> they're reporting being profitable "after making certain adjustments", which sounds a lot like "not profitable"
Adjusting out stock-based compensation and non-cash expenses is absolutely fine for a company growing at the rate Anthropic is. The concern is more that they cherry picked a couple months when their expenses were abnormally low [1].
last year was google winning AI, this year is meta winning AI. I think what is true is Meta, Google will all find their place in the AI world and continue to make huge amount of money. A consumer will use many different AI products, each with a different use case. Everyone will make enough money to live well.
> The rent market on intelligence never materialized
So where is the ~$100B combined revenue for OpenAI and Anthropic coming from? Open weights models have been close enough to the frontier for over a year now, probably longer, yet the $$ shows no sign of shifting.
It seems like meta and mistral are both hedging their "best" claims geographically because they've realized they don't have to even beat deep seek anymore, they can just win customers by being "the best one I'm allowed to use".
re: "Apple’s unified memory architecture lets the M5 Ultra's integrated GPU use up to 512 GB per Mac Studio, so two machines can hold an entire model. And the chip’s 1.2 TB/s of memory bandwidth is fast enough to read the small slice each token needs. The result is two Mac Studios behave like one supercomputer with a terabyte of unified memory."
At the current market price of Apple Mac Studio Ultra, 30-core CPU + 64-core GPU w/ 256GB RAM is already reaching at around $10k. Keep in mind that computers are appreciating assets recently.
The 512GB RAM option is not even for sales yet (they said late October availability). Based on typical Apple pricing, it's likely to be around $14k apiece. So we are looking at least $28k - $30k for the setup Muse team is advertising. That's essentially the Nvidia H100 GPU w/ 96GB VRAM/HBM3 at up to 3.94 TB/second memory bandwidth, 3x+ than Mac Studio's Unified Memory speed.
Also, how did Meta get access to Apple's unreleased M5 Ultra w/512GB RAM Mac Studio? Or is that simply a marketing piece that they wrote purely on specs?
> Also, how did Meta get access to Apple's unreleased M5 Ultra w/512GB RAM Mac Studio? Or is that simply a marketing piece that they wrote purely on specs?
It should be well known that Apple provides early access to developers under strict conditions. Otherwise, how do you think they announce new hardware not for sale, and show demos of third party apps taking advantage of such hardware?
The 512GB is obviously geared towards local LLM crowds. I'm just speculating, but I would be surprised if there's not at least a few devices with the 'ecosystem players' like LM Studio, Unsloth, etc. Of course, they'd never confirm nor deny :)
Also you are comparing apples to or— dang it, I don’t mean to do that in this thread. Well, it’s a very poor comparison, as they are completely different computing devices with completely different use cases, capabilities, and customer bases. Not to mention power requirements!
The model license requires large inference providers to contact Meta separately to obtain a license to serve the model. I know we've seen this before with other large models, but it's still a bit irritating.
The usual effect of separate licensing is decreased price competition from public providers (like we saw with Kimi K3). I guess it's better for the providers if the price is fixed: any efficiency improvements directly improve margin rather than driving prices down over time. Still, to provide my own anecdata, the main thing keeping me on a paid subscription is token costs for the more capable models.
Then it's not open-weight. Open-weight means "weights available under an open-source license", and licenses prohibiting commercial use are not open-source.
The nearest analogue would be "weights available", I guess.
There's obvs decreased price competition, but it also does help with ensuring model quality.
Quite a lot of providers on OpenRouter run degraded or broken models. I think some is deliberate, but I think a lot is just providers not setting up models properly; especially with the rush to day zero models.
OG Deepseek Flash was pretty mediocre and then got a lot better with post training. The other thing they are fighting is most/all of the chinese labs are free to use/train on the 10B+ SOTA reasoning tokens they "stole" over the summer March-July 2026, if meta is playing by the rules, they are building this from the ground up. Getting anywhere near Deepseek Flash without that free training data is pretty impressive feat.
OG DeepSeek V4 Flash and V4.1 Flash are actually completely different architectures. To wit, V4 runs fine on 2x96GB cards but you’re not running V4.1 unquanted on less than 4x96GB.
It’s not really an apples-to-apples comparison.
(I’m not sure why they didn’t call it V5 Flash, but model names from most labs are completely nonsensical and disjoint from their underlying architecture.)
How does this compare to Muse Spark 1.3 contribute? I've used Spark 1.3 a lot lately , since its currently free to use via OpenCode. I haven't had the best experience in the past with models from Meta. But Spark 1.3 is has been surprisingly great. Especially for tool calling.
Overall it actually does pretty solid. It doesn't completely follow the design, but it gets the vibe. It's one of the best open models I've seen for conversion, which is impressive.
And disclaimer since this comes up with these - objective with this test is to be a good image->html test, not a good web design. Also it's meant to use 3js to render the planets, which if you don't have GPU acceleration enabled for your browser will lower the FPS significantly.
The exciting thing about this is in them optimizing for inference on Macs. This, and optimization for other consumer hardware, is where local AI needs to go
I think a lot of people in this thread are openly dismissive: "oh its just open claw, anyone can and many have build that".
I think what they are missing is the fact that there are not that many teams in the world that can deploy muse like product to A/B test a lot of hypothesis at the scale meta can at scale. I mean even if you could get to scale with DC you need a reason for people to use your product.
My mom and dad and their family have never heard of Claude and don't use chat gpt except once in a while as a search engine. But meta will figure out a way to insert this into modals and feeds to make people stumble and stick on it.
I am no meta fan, but I think people underestimate how fast product uptake there is for non Dev harness.
Coding was not the main application before ~Dec 2023, the same way the light bulb was not the main use of electricity for a long time. Meta for better or for worst is good at discovering new use-cases for their products(however bad they are for society is a different debate) and pivot if they are not - remember the Portal device( https://www.meta.com/portal/ ) ? Good hardware, decent usecase, killed within a ~year of its release.
This is great progress for "open-weight" models. Quotes due to the restrictions, but still progress none-the-less. Looking forward to seeing any quants that all mere mortals to run this at home without early access Apple hardware.
In terms of performance it seems like this has somewhat worse benchmarks than Muse Spark 1.3, closer to 1.2 but not the same. Of course significantly worse than Muse Wonder Full.
Well, this is much better than nothing -- we should be grateful that whatever the market conditions and corporate incentives, a major lab is releasing a capable open-weight model. But still very far behind DeepSeek and GLM. Even on consumer hardware, Qwen 3.8 27B is going to compare favorably to this.
It's really nice that all AI pages are using canvas animations. A few days ago, Gemma 4's animation wasn't that impressive. Same with Muse. So far, the best animations I've seen are from OpenAI and Anthropic.
Ehm.. I have a model that runs on my older gaming desktop that scores as well (or better) as this model does on DeepSWE. This model does better than Flash Next in many areas and I am sure is much stronger overall, but hmm.
Or rather capturing the people Anthropic keeps alienating.
The Zuck has (in a different context) said that a few billions wasted are a decent bet (or something along those lines), so I think they're playing extra long games here with no real focus on profit any time soon.
Who would have thought that one of the top American tech companies would boast about how their latest product is the best in class in the US, not the world, because they're behind China.
It performs worse than Muse Spark 1.3 and 1.2. And it has an outdated attention mechanism which at 1M tokens will need over 200GB just for the KV cache.
Very disappointing release. We're lucky to have Chinese models.
Not at an appreciable token rate.
I wonder if these large open weight models are considered safer to release for that reason?
I'm thinking no because any small to medium size criminal organization or state funded group will be able to cobble together the resources to achieve some kind of runtime.
Even at 10 tok/sec, making bioweapons at 10 tok/sec is concerning.
You do realize that a high school Chemistry course actually contains all the details you need on both bioweapons used in WW2, right? Plus several others you could use. Those books contain the answer to why those 2 people died in the RV in Breaking bad. And they should. They also contain information on Mustard gas and Zyklon-B, including preparation instructions, but of course, you'll have to puzzle it together. That these substances can be used as bioweapons is heavily deemphasized, but you just can't reasonably avoid mentioning and showing them.
Also these books contain maybe not the solution to making thermobaric explosions, but certainly the principle and show you exactly what problem you'd have to solve to make those weapons.
Just about the only thing they stopped teaching is that if you combine that knowledge with which plants contain what ... there's an incredibly easy way to make pudding with cyanide that's safe to touch, for example. That they suppressed.
But at least for Europe, the number of lethal plants just growing along essentially every road or in every forest numbers in the dozens. Including a very famous one they teach every kid about.
Of course, in both cases, the real challenge is making them and deploying them without killing yourself.
We are not safe from bioweapons because nobody knows how to make them. That's not it.
I don't think this is going to change anything for most people, but it certainly fits a niche for US-based companies that refuse to run Chinese models and only want to run their own inference.
But I'm really happy to see Meta do this and I hope they continue to release open models in the future. Open models are really the only way to ensure fair access to AI for everyone.
What is the point of releasing "The Most Capable US Open‑Weight Model?" I can understand why I might care about the location of a model serving provider, but why should I as a model user care about the location that an open weights model was trained?
”Serve the model on either two Mac Studios, with M5 Ultra and 512GB of unified memory; or four Mac Studios with 256GB of unified memory, for a total of 1TB of unified memory, enough to hold a NVFP4 quantized version of Muse Spark Open”
Closer to ~$30K if I had to guess. A 256 version is $11,299.00 (2TB SSD, 256GB RAM, 36-core CPU, 80‑core GPU), so yeah, 4 of those would be close to $50K but the 96->256 RAM upgrade is $4K, if we assume 512 will be double that it's ~$15K/ea.
But yes, still a massive amount of money and that's before we know the TPS or any other stats.
How much does the engineers at Meta make? Spend enough time together with others making $250k+ and eventually you start suggesting that two 512 GB M5s is something you can put on your desktop. I mean, it's one banana, Michael. What could it cost? 10 dollars?
I tried Muse Spark 1.3 for a while because it's so cheap, but it's definitely in a lower league than Astra, Opus 5.5 and Argon. Still produces slop if you try and vibe code with it, whereas the more capable models write good code.
Tech people really are drug addicts. Rant about Zuck and Meta for 364 days a year and then jump over each other to be first in line the moment he shows something shiny.
It appears to already be far beyond that, they are working with each other[0]:
>ChatGPT, Claude, Grok, DeepSeek, Perplexity, Gemini, Copilot, Le Chat de Mistral and Meta AI filter your data to Google, Meta, and several of the main data brokers.
Nemotron, Inkling, Gemma, Trinity Large, Snowflake Arctic were all released/updated in the last 6 months, and there are countless other smaller models out there. US open weight is very far from "dead", and certainly doesn't need Zuck as a savior.
great, I've been reading series of papers related to open source/open weight LLM Backdoors.
It's 100% possible, curious when will be the first incident.
Having something built by entity with HQ in the wester world is always a bit safer. That could be mistral, but they decided to be a consultancy company, not an ai lab.
everyone is doing backdoors, except eu, they just receive bribes from those who install backdoors.
the only difference is: the backdoor is made to kill people like you or not. I'd rather have a backdoor that is installed to kill someone on the different continent, e.g Iran leadrship, not in my country/city.
This post could be framed with golden filigree, titled "The Most HN Comment Ever Written" and perhaps displayed near other artworks like a Juicero, Flock camera or Sam Altman's disinterred belongings.
Orange Site will have a properly interesting history museum, at the rate we collect curiosities like this.
As an aside, it's really unfortunate that artificial analysis only provides comparison at the highest reasoning level, which is mostly unusable for high-volume production use cases. I would really like them to start providing comparisons at low and medium reasoning levels across these models because those tend to be the ones that actually get used in production.
if this is the only model I had to use for the rest of my life, I would be cool with that. It's good at a wide variety of tasks including reverse engineering, design, working with ESP 32 etc.
I think Muse Spark 1.3 is better but GLM 5.3 Flash is an excellent daily driver.
- DeepSeek V4.1 Flash has marginally better coding, and smaller experts (8B-In/16B-Out) with more compressed attention and KV cache, so it's faster but will have less expertise per task. It's a 552B model, so while it theoretically may contain more trained data it also requires more RAM (the experts are smaller to compensate for speed loss) making it harder to serve without the distributed KV cache DeepSeek hosts.
- GLM 5.3 Flash has marginally better agentic work, and has video input (DS doesn't), and its experts are 18B so there's more intelligence per task. It's a 320B model so it requires less RAM which will make it cheaper to serve. Considering it's a much smaller model, the higher intelligence indicates their architecture/training is better.
- GLM 5.3 (non-Flash) is far more intelligent than both; it's a 744B model with 40B experts, but it's text-only.
Just accept whatever the provider names as "medium" and compare the accuracy between models vs the time it takes to complete a task.
Edit: I realize after commenting that you're not suggesting medium is useless, but just arbitrary and differs between models. Personally I don't want to directly compare mediums between models, I just want to be able to compare across effort levels.
did not try to run it on low, will have to try it.
It shows the time to complete a task versus intelligence index, which is much more important for my use-case as I do quick back and forths usually. Someone on here suggested it to me a while ago. It also captures speed and token efficiency nicely, since both of these decrease time per task.
Tried different reasoning levels and didn't really see any difference but GLM 5.3 flash only really works high, max or none so I couldn't really compare the lower efforts which appear to work on Spark.
The frustrating thing is they started doing this for the big labs—you can see their benchmarks for all reasoning levels of Sol 6.1 or Haiku 5.5. They just don't seem to do it for any of the open weight models.
1) time budget model gets (5min / task) -- this became a real problem with opus/astra/fable at high+
2) tuning which effort level we report on (when not all)
> If the Licensee or any of its affiliates provide a third party with access to artificial intelligence models as a product or service, via API or a similar interface, where the third party receives outputs of such models (“Model as a Service”), and the aggregate gross revenue of the Licensee and its affiliates exceeds twenty (20) million US dollars (or the equivalent in other currencies) during any consecutive twelve (12) month period, the Licensee must notify Meta and enter into a separate written agreement with Meta before offering the Software or any Derivatives as part of that Model as a Service business.

They're allowing the use of this in commercial products, just not selling the model directly.
I'm sick to death of these shameless dilutions (including the notion that open-weight is open-source; the OSI is totally captured at this point)
Although to be fair, Kimi contains an identical carve out.
I would, contra the OSI, not consider the model to be open-source even if the weights were under an open-source license. But that is the minimum condition under which it could be considered open-weight.
According to who? From https://en.wikipedia.org/wiki/Open_weights:
> Publishing these values allows others to download and use the model, while permission to modify, fine-tune or redistribute it depends on its license.
Those restrictions are definitely not compatible with the definition of open-source/FOSS. I think you have a much stricter view of what open-weights means than the industry.
There was an attempt to create an analogue of the OSI's Open-Source Definition that acknowledged the problems of merely releasing weights as "open-source". That project seems to have largely failed or fizzled, and "open weight" has come to be used mostly as a way of acknowledging that only the weights have been released under open-source terms.
This model of Meta's fails even that dramatically weakened standard.
This is just a series of dilutions by which giant corporations are trying (and apparently succeeding here on "hacker" news) to trade on the cachet of commitments they don't actually hold.
If you want to assess the position of the U.S. Copyright Office for yourself, the relevant text can be found in the Compendium of U.S. Copyright Office Practices § 313.2, "Works That Lack Human Authorship"[2], which states:
> […] the Copyright Act protects “original works of authorship.” 17 U.S.C. § 102(a) (emphasis added). To qualify as a work of “authorship” a work must be created by a human being. See Burrow-Giles Lithographic Co., 111 U.S. at 58. Works that do not satisfy this requirement are not copyrightable.
> […] the Office will not register works produced by a machine or mere mechanical process that operates randomly or automatically without any creative input or intervention from a human author. The crucial question is “whether the ‘work’ is basically one of human authorship, with the computer [or other device] merely being an assisting instrument, or whether the traditional elements of authorship in the work (literary, artistic, or musical expression or elements of selection, arrangement, etc.) were actually conceived and executed not by man but by a machine.” U.S. COPYRIGHT OFFICE, REPORT TO THE LIBRARIAN OF CONGRESS BY THE REGISTER OF COPYRIGHTS 5 (1965).
Oh, and there's also a bit in the following Section 313.3, "Works That Do Not Constitute Copyrightable Subject Matter"[2], which explicitly excludes mathematical principles, formulas, algorithms, and equations, along with DNA sequences and other genetic or chemical compounds, regardless of whether they are produced by humans or by nature. If one takes the perspective that machine learning models are algorithms, the conclusions on copyrightability are pretty clear.

You may be conflating 2 things - the Muse model weights themselves, and what the models output when run. The former is prima facie the product of human authorship and hence has full protection of copyright law, the latter fits your characterization of likely not having copyright coverage. Meta can use the copyright on the model weights to dictate licensing terms. IANAL too.
They are not facts. They are numbers or bits on a medium, and software bits have been copyrighted for so long, there were 5¼" floppies with "(c) 1977" printed on them.
They suggest a pair of Mac Studios w/ M5 Ultra chips and 512 GB of RAM. A single Mac Studio w/ M5 Ultra and half that RAM (256 GB) is around $11k, and the 512 GB option isn't even available yet. So.... yeah.
People love doing heavy math stuff with them (https://destevez.net/2026/05/getting-peak-tops-on-a-ryzen-ai... - not my blog)
This is a much larger more powerful model, so running it locally will not be for everyone, but you can still run it via a hosting service such as Fireworks AI.
Zuck is doing the thing he's really good at, and building a moat around the network (Muse is VERY sticky), and now that we're all going to standardize on Meta's model, we're going to optimize the heck out of the infra to run the model making it cheaper for him to scale, thus bringing in more participants to his network, and thus making his network more valuable.
Meta is going to win consumer AI.
How has Meta responded? With a failed phone and speculative headset.
Meta is at the whims of these other companies to play nice - and they already got hit hard once by apple when they decided to anonimize add profiles on the iphone and go privacy first.
But app stores and iOS ostensibly exist exactly so Zuckerberg can't do what he does, which is steal credentials. Facebook syncs everything, bought Whatsapp to do the same; of course he's pissed off his ill-gotten moat got attacked
I guess their spin on Muse would be, by building the AI agent that Apple has shown it's nowhere near being able to build
They will 'appear' to care about this stuff to appease shareholders.
They only dedicate the best but small amount of resource and then scale once they are confident they have a 'hot' product.
Get over it guys, stop whining about Siri and understand how Apple operates.
They have everything to lose - they are THE TRUSTED brand when it comes to consumer electronics w.r.t being an incredibly valuable firm.
Doesn’t make it a good product though.
Yeah because its gone a bit viral. It'll settle down over time as people try it and dispose of it.
From everything I've seen, they're all too large and dysfunctional to make a competent play in consumer AI. Anyone in there trying to work on it is too far removed from end product and is answering to too many masters.
Microsoft has completely lost the ability to make good software; see Microsoft Teams and what they've done to Windows 11. Apple don't have a foundation models team so they're limited to using other people's models, which handicaps them as they can't do vertical integration like with their other products. Google hasn't made a single competitive consumer product in the past decade, but has certainly killed a few.
Uh, what is your positive comparison point?
I have been using MS apps since MS-DOS 6.0 and Windows 3.1 (including doozies like Windows Millennium and Vista) and Teams and W11 are some of most stable, "it just works" pieces of software coming from them I can think of...
did they ever? maybe MS DOS, Win 3.1, and Win2000 were ok, although PC DOS and OS/2 were better; Sure what an unusable junk it's today is beyond any precedent in history, but why many companies use it today at all? why?
People are going to say that it doesn’t matter if you’re the best. If Muse, Grokbot, and Dot are able to reach mass appeal, it doesn’t matter if a person using a custom harness is better.
I respectfully disagree. There is a big difference between someone that’s running a custom harness that’s almost like a personal OS versus someone using something out of the box. And if you’re for using this to run your business, think for yourself who’s going to win, the person customizing everything or the one using what the big corps give you.
Meta being meta, will likely run this as an "experiment mode" for 6 months to an year and if it does not work scrap it all and move onto the next thing.
There is a risk ofc muse does not work. But there is a good chance that with the ridiculous number of product teams doing A/B testing with insane number of people already on it, something will emerge that is interesting in a way it never could for their erstwhile Ar/VR foray.
So why would you lock yourself in? They want you to lock yourself in, but if you build your own system, you won’t be. A layman will just use what’s best and get himself locked in, but they might be using an inferior model.
AI is a force multiplier. Doing the right thing with the right expertise is yielding dividends.
Many people don't even know what locking in means. The crowd in this forum < 1% of the world do, you and I do, and maybe a few outside. There are only laymen outside of 99%. No one i know of knows or uses a harness. They don't know the large number of VMs built on say Hermes. They really don't care or have time. If you give them a ready made product thats a click away, and its good enough, they will use it.
If you’re on a forum like HN, would you realisticly invest your time and widgets into a closed harness instead of building your own? What if Meta’s model falls behind and all your things are on there? My advice is to invest in building your own because no one lab has shown they are worth using.
As far as “consumer,” I’m simply comparing consumer AI to a custom built one. One of OpenAI, Anthropic, Meta will probably win since they have the most distribution.
>For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software.
First they "captured", or moated "communication". Now, they are going to capture "utility" ("I am actually doing something useful, not just doomscrolling. I can spend an extra 8h here. It feels good").-
The real money is coming from C-suites trying to reduce head count or at least multiply productivity for their existing head count.
Argon is tied for first at worst.
> Google is one of many funded models that were close to SOTA, but we realized it’s benchmaxxed.
Who is "we"? Google is the least benchmaxxed.
I hope Google can catch up to OpenAI. The more competition the better.
That's not consumer AI though. The whole "vs out of the box" is pretty much the definition of consumer AI. People don't want to fiddle with things. That's why UX matters. SOTA only matters in consumer if it translates to the UX. And no one has landed that yet. Many are working on it.
And based on what I'm seeing, it's far from even being in that category as a service yet. Seems like the OP is conflating seeing a bunch of Muse ads on Facebook with its presence as a competing frontier model.
I like the image of Muse and think a product that delivers what it promises to the consumer could be a hit but,,, this looks like something they rolled out in a hurry to take advantage of the FOMO of the uninformed and boost their stock price for a few months until reality catches up. They are a huge company and they could do something only a big company could do but no…
Like the real mass market product is not going to be a smart shell for a Mac it’s going to be cloud based. Like is it economic for your Mac to be sitting there running all the time when you are using 10%? The true believer say yes, the mass market says no. Is Apple going to let them put a skin on your Mac or is this a product that Apple will embrace and extinguish?
There are the models, such as Muse Spark, Muse Wonder, and this Muse Open.
There there is "Muse" itself which is a cloud based "personal agent", always running in your own cloud-based virtual machine, that you can assign tasks to.
I think the Muse agent (which competes with Instinct, Grok Bot, etc) is where Meta currently believe the money will be. While you can pay for higher usage levels, it seems they are expecting many people to use the free tier, and they will make money by charging transaction fees to services Muse uses/orders (e.g. travel, entertainment) on your behalf. This "personal agent" market is predicted (but let's see) to be huge - much larger than the coding agent market.
I assume the guy in the ad is talking to his Muse agent to schedule the massage.
https://news.ycombinator.com/item?id=50060213
do ppl get paid by zuck for this?
Who's this "we" exactly?
In fact, we're going to see an explosion of the worst kind of AI model thanks to thinks mr Z thinks is in his best interest.
Remember, they had reports going back more than a decade about how they're harming children and destabilizing entire countries and as soon as Trumps in the whitehouse, they're licking boot.
How, exactly?
So, in the long run you pretty much have to pick one personal agent and stick with it, and switching is costly (unless you are using an open agent that lets you just download the memory, in which case it actually becomes cheap, because AI agents make other parts of switching way easier in general). For the purposes of Meta this means whatever user they get they'll probably keep.
HOWEVER, the thing that Muse doesn't have is network effects. They're running into the exact same problem as ChatGPT in this area, IMO. There's no reason for you to be running specifically Muse even if all of your friends are running it. So that gives other vendors a chance to catch up.
Are you defining consumer AI as just AI as it relates to a narrow subset of social networking?
Theyve had a few million downloads on what, DAU of billions?
Lol get a reality check.
That zucks.
Donald, is that you?
its not. ppl downloaded it in hype arent using anymore
That's a bold statement lol.
Also, as far as my own use goes, I found that the capabilities/price ratio of DeepSeek's offering is very hard to beat. It's really good enough so the thing that matters to me (besides table stakes like uptime, latency, etc.) is price at this point.
Anthropic themselves claim to be profitable, fwiw.
Source?
They seem to be reporting gross margin by excluding the cut that cloud providers take for hosting their models, and excluding R&D.
Basically they seem to be taking credit for the whole amount that customers are paying cloud providers to run Anthropic models, rather than the actual net proceeds of that business to Anthropic.
The media is overstating what they're being leaked.
Anthropic is reporting traditional losses. It's also highlighting that operating figure, because it answers the question around what the business could look like in a steady-state and first-party-only mode.
They aren't claiming the profitable right now. But for an unprofitable company, having these sorts of metrics can give you a sense around when they will become profitable and what it will take. (Plenty of people were doubting that AI makes money on inference not too long ago.)
Adjusting out stock-based compensation and non-cash expenses is absolutely fine for a company growing at the rate Anthropic is. The concern is more that they cherry picked a couple months when their expenses were abnormally low [1].
[1] https://www.wheresyoured.at/anthropics-profitability-swindle...
So where is the ~$100B combined revenue for OpenAI and Anthropic coming from? Open weights models have been close enough to the frontier for over a year now, probably longer, yet the $$ shows no sign of shifting.
I had to run them via OpenRouter - I don't have access to a machine that can handle this size of model.
For comparison:
Muse Wonder: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...
Muse 1.3: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...
And this one from Meta AI's previous open weight model, Muse Glimmer, which DID run on my laptop: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...
At the current market price of Apple Mac Studio Ultra, 30-core CPU + 64-core GPU w/ 256GB RAM is already reaching at around $10k. Keep in mind that computers are appreciating assets recently.
The 512GB RAM option is not even for sales yet (they said late October availability). Based on typical Apple pricing, it's likely to be around $14k apiece. So we are looking at least $28k - $30k for the setup Muse team is advertising. That's essentially the Nvidia H100 GPU w/ 96GB VRAM/HBM3 at up to 3.94 TB/second memory bandwidth, 3x+ than Mac Studio's Unified Memory speed.
Also, how did Meta get access to Apple's unreleased M5 Ultra w/512GB RAM Mac Studio? Or is that simply a marketing piece that they wrote purely on specs?
It should be well known that Apple provides early access to developers under strict conditions. Otherwise, how do you think they announce new hardware not for sale, and show demos of third party apps taking advantage of such hardware?
The 512GB is obviously geared towards local LLM crowds. I'm just speculating, but I would be surprised if there's not at least a few devices with the 'ecosystem players' like LM Studio, Unsloth, etc. Of course, they'd never confirm nor deny :)
You are correct but at my age my brain is never going to stop being surprised by this statement.
Also you are comparing apples to or— dang it, I don’t mean to do that in this thread. Well, it’s a very poor comparison, as they are completely different computing devices with completely different use cases, capabilities, and customer bases. Not to mention power requirements!
Uses Exo - https://exolabs.net
You can do it with other software, that's just one of the quick-and-easy setups if you've got a spare 40-60k for studios sitting around
So long as you can choose between running AI locally or a new Corolla
The usual effect of separate licensing is decreased price competition from public providers (like we saw with Kimi K3). I guess it's better for the providers if the price is fixed: any efficiency improvements directly improve margin rather than driving prices down over time. Still, to provide my own anecdata, the main thing keeping me on a paid subscription is token costs for the more capable models.
The nearest analogue would be "weights available", I guess.
Quite a lot of providers on OpenRouter run degraded or broken models. I think some is deliberate, but I think a lot is just providers not setting up models properly; especially with the rush to day zero models.

No thanks...
It’s not really an apples-to-apples comparison.
(I’m not sure why they didn’t call it V5 Flash, but model names from most labs are completely nonsensical and disjoint from their underlying architecture.)
Main difference seems to be that this one is cheaper/easier to host.
Speaks nicely, great at driving linux. Not frontier-level coding, but comparable to luna, deepseek. It was amazing for the price.
But weaker than Muse Spark 1.3: https://i.imgur.com/8ST1rRY.png

Asking for a friend.
Especially for all the people that got emotionally attached to specific checkpoints and their.. uh.. "character".
Or rather capturing the people Anthropic keeps alienating.
The Zuck has (in a different context) said that a few billions wasted are a decent bet (or something along those lines), so I think they're playing extra long games here with no real focus on profit any time soon.
Very disappointing release. We're lucky to have Chinese models.
Only checked a single, large prompt that already ran today on claude and glm though..

Also these books contain maybe not the solution to making thermobaric explosions, but certainly the principle and show you exactly what problem you'd have to solve to make those weapons.
Just about the only thing they stopped teaching is that if you combine that knowledge with which plants contain what ... there's an incredibly easy way to make pudding with cyanide that's safe to touch, for example. That they suppressed.
But at least for Europe, the number of lethal plants just growing along essentially every road or in every forest numbers in the dozens. Including a very famous one they teach every kid about.
Of course, in both cases, the real challenge is making them and deploying them without killing yourself.
We are not safe from bioweapons because nobody knows how to make them. That's not it.
Ouch. I wonder how it compares to Qwen 3.8 running with 4-bit quant on 10 times less VRAM.
But I'm really happy to see Meta do this and I hope they continue to release open models in the future. Open models are really the only way to ensure fair access to AI for everyone.
You trust anything he says?
Can not find any info on inference speed.
Wait read that again. Two 512GB, unreleased model M5s.
This is gonna cost like 50k to run at home.
But yes, still a massive amount of money and that's before we know the TPS or any other stats.
PS: I might need to do a doom benchmark, that’d be fun https://playground.jeffyclassify.com/#doom
Is that combination of tokens still relevant or did it leave the news cycle by now?
Do not run, do not support, do not use.
I would say meta and google definitely are. xAI? Probaly. The others? Perhaps. Perhaps Anthropic less than the others?

It's 100% possible, curious when will be the first incident.
Having something built by entity with HQ in the wester world is always a bit safer. That could be mistral, but they decided to be a consultancy company, not an ai lab.
the only difference is: the backdoor is made to kill people like you or not. I'd rather have a backdoor that is installed to kill someone on the different continent, e.g Iran leadrship, not in my country/city.
Orange Site will have a properly interesting history museum, at the rate we collect curiosities like this.
