I've been using grok 4.5 with grok build soon after it came out and dropped claude. primarily for personal code. It communicates better. While that might not sound like a big deal it is. It doesn't give me a wall of text, tells me what I need to know and I'll make the actual decisions. It is very quick as well which means the sessions are far more interactive, I'll be steering it more. I sometimes cross check with codex and sol, but the daily driver is grok for me.
I found it has improved my productivity and output over claude where it felt like claude was giving me work to do. furthermore with the recent claude watermarking thing, I'd rather use grok or openai.
If anyone is curious download grok cli and throw a couple of prompts at it. you'll be surprised.
Cursor, since Grok 4.5, has had an incredible deal for frontier level models, their subscription now goes way further than OpenAI or Anthropic. Even on their lower tier plans you can use a lot tokens on their of their first party models (Grok and Composer) and not really run out comparatively. Combine them with an orchestrator and implementor type setup and it goes even further.
>their subscription now goes way further than OpenAI or Anthropic.
Until it doesn't...
Honestly, this entire OpenAI reset credit fiasco this past week has convinced me to rip off the Codex and Claude Code bandaids and start building my own proper Pi Coding Agent running models that I select and pay for on openrouter.
And I am feeling a lot better about it now that I've finally got it working.
I don't get the point of this. We all seem to agree that these companies have almost no moat, if one stops being a good deal, you can switch to another. That doesn't invalidate the existence of a deal that is currently good.
But still for US frontier you're paying 10-20x more per token compared to their limited subscriptions. For China frontier you'll be good though, and that might be the future anyway.
Your reason for the rate limit reset is speculative. Here's a history of them and tweets that correspond to when they happen. Others can be the judge if they believe the stated reasons or not: https://codex-resets.com/
Can you explain what you mean? These days courtesy of an addictive reset game OpenAI is playing, I can't find anything with frontier intelligence that's more cost efficient...
If they didn’t constantly reset, they’d be about the same as Anthropic.
Right now, I find that Grok offers better value, uses fewer tokens per turn, and makes better code. I haven’t tried Cursor because I don’t want to change editors again, but maybe I should try it…
Not that I know of. AA's token use metrics (mentioned in this article) are indicative, however. They say explicitly here that the Grok models are notably token efficient. This is my experience.
The benchmark article we're replying to shows that Grok token usage is at least on par with the latest OpenAI models [1], and significantly cheaper per token:
Yeah, even without the resets, chatgpt subscription currently goes quite a bit further than an equivalent anthropic plan. The main reason to have an anthropic plan is to get access to Fable 5 if you feel the quality of output makes it worth it.
I'm willing to pay 2x for a 10% smarter model. Intelligence matters that much (because 10% smarter probably saves, on average, several hours of human time).
For building a full stack custom CRM and media pipeline tool with video conversion, transcription, and indexing. Supabase, AWS, Meili, NextJS, GCS - lots of surfaces and planes.
4.8 basically couldn't do it, I abandoned the project as the fallback was, "current business processes".
With F5 it's been 4 weeks and almost ready for production release.
I have the same quality results with Fable. With just a brief prompt, it created a great static website with a beautiful animation of a workflow. Gemini's output was so poor that I closed the chat. And with Codex, the results were bad, so I discarded them.
I believe they are the only western provider that has Kimi K3 on a subscription plan today as well. I would love to ditch Anthropic and be on Kimi if there were a subsidized plan like that with ZDR
I believe it's one of the models you have to go in to your settings on and enable Chinese providers for to use. Could be mistaken. I wish there was a clear list on this.
They don't do request based pricing anymore. Its just token based (1 credit = $0.01) plus some bonus credit based on which plan you subscribe. So for example a $39 plan get $70 of credits.
Yeah, I know, but "credit" translates differently because the models bill at different rates, which gets turned into "multipliers" (or at least, it did).
Have they converted entirely to transparent API rates + base allocation now? One of the reasons I left was that if I was going to be billed at API rates anyway, I'd just rather use the APIs. The value proposition still sucks for individuals now, when the other major providers are bundling at below-API rates.
I’d love a subsidized Kimi subscription too. The official Kimi subscription is always out of stock and doesn’t have great limits, while the K3 allotments on OpenCode and Cursor don’t seem to last very long either.
Kimi is expensive . Cursor with subscription is cheaper , grok 4.5 per task paid per tokens ( no subs ) is also cheaper .
If you willing to share to no zdr, meta is waaaaaay cheaper vs Kimi.
With recent offerings from spacex and meta , I hardly imagine why would you pay money to any Chinese vendor it’s not as cheap and it’s not as intelligent neither .
Maybe deepseek is an exception , but it’s only good for narrow use cases that probably goes into modal.com and other gpu + fine tune me easy vendors , not vanilla dumb but cheap model .
When I last used Cursor their subscription covered usage of ~$20 per month. Have they switched to a subsidized subscription model like ChatGPT and Claude?
SpaceXAI is the only frontier model company that had its own compute/date centres and soon chip making factory, I think they will pull ahead with cheaper tokens similar intelligence and better harness/tools. Grok build is 2-5x faster than Claude Code in my opinion.
From Matt Levine's description, SpaceX has a governance model that explicitly makes it resistant to shareholder lawsuits. It's not a Delaware corporation.
It might or might not work long-term, but I wouldn't count on courts to help.
There’s some number of supposedly unsupervised Teslas actually operating in Austin, but what I’ve seen suggests it’s more like a dozen.
And extreme skepticism is warranted that they’re actually fully unsupervised, given Tesla’s repeated lies about this. They’re likely remotely monitored and operated.
SpaceX is run by an absolute ghoul who managed to get away with securities fraud ("funding secured"), what makes you think there's any accountability left in public markets?
OpenAI is almost there, and Anthropic is pretty close behind. In the next year or two all major AI companies will be vertically integrated to a good degree.
highest selling is not same as cheap - apple also have the highest selling iphones among smartphones and they are still pretty much the most expensive (and usually not the best either these days).
> I think they will pull ahead with cheaper tokens similar intelligence
They obviously have a huge token cost advantage of the AI labs they are renting compute to, at least for now while they can charge current crazy rates for GPU compute.
Except EUV lithography is the most complicated industrial process that exists and they won't have usable yields for many years if ever. I don't think Musk actually expects these fans to ever actually make sense they just let him hype and distract.
Light generation is the most complicated part and Elon plans on doing Free Electron Laser (FEL) which is not as complicated as self contained tin based solution that ASML uses now
Why do you give Elon any credibility? FEL is not proven at all and is much much riskier than using existing EUV machines. Plus if it breaks all your machines are down until you fix it.
The main issue I have with grok is that Musk, its owner, did 2x seig heil at the presidential inauguration, and proceeded to gaslight the world about it (this is a strong form of dogwhistling, kind of a dog bullhorn). Therefore all services which have anything to do with Musk are ineligible for use - they are directly funding the worst kind of person.
The rental deal can be terminated by either side with 90 days notice, and presumably Musk would do so if he needed the compute or generally thought it advantageous to do so. For now he doesn't need the compute.
The rental deal may also have been at least in part to juice the SpaceX IPO and to help Anthropic stick it to his enemy OpenAI.
I recently decided to get an AI subscription and evaluated Grok vs chatgpt. Went with Grok because it's all-around good enough at day to day stuff, integrates with my Tesla, and the image/video generation is great. Kids love whimsical videos of them riding dinosaurs.
Feedback: I'd like Grok to have more connectors (I see OpenAI just added Apple Health, that would be nice to have, and I wish it could read my Onenote notebooks) and for existing ones to be improved. I gave it access to my gmail and asked it "what was my last electricity bill?". It failed to find it, even when I told it the exact subject line to search for. Something about not getting any data back when trying to get the email contents.
Not the model but the app - with Claude I can work on my mac using Cloud environments, leave the office, open Claude on my phone and respond. I can't change model if I have to stop that workflow.
Does xAI have plans to do Mac/iOS apps with cloud environments? When can we expect them?
Grok doesn’t have those features, and people who like to make adult content have been complaining for a while how Grok has made it a lot harder to do so.
That is good news for Grok team. However, most of the time cost comparing to the result is secondary, and better results and conclusions can come from mixing AI brains together.
I have. He was using it due to philosophical reasons the same way many people have philosophical reasons for avoiding it. I don't know how many people are like that, but it's not exactly where you want to position your product if you're a business.
Personally - and I know I'm not alone with this sentiment based on comments I see on this site - I wouldn't touch Grok no matter how good or cheap it is. I don't trust Elon and I don't want to give another dollar to the world's richest person who turns around and uses the money to interfere with elections. The guy I know uses it for essentially the same reason I won't use it.
Perhaps customers choosing your product for irrational philosophical reasons is exactly how you'd want to position your product if you're a business. When it comes to margins, the only thing better than a price-insensitive customer is a quality-insensitive customer.
Versus Sam,Dario or the CCP? Im all for running local models but im sor far from being able to pay for a large model hardware setup. My strix halo box is like driving a beaten up vespa when the frontier models are Ferraris.
I probably have the same strix halo box as you. It's slow, although mostly tolerable, but even 128 GB isn't enough to run good models. Where that leaves us is giving money to somebody to get access to frontier models. I don't like any of those guys either, but some appear worse than others. FWIW, I mostly use Anthropic models. And CCP and their distilled models notwithstanding, at least they release open weight models at a lower cost. It's not like any American company can claim the higher ground these days anyway, especially when they trained their models on pirated content and trash our neighborhoods with their datacenters.
Yes, ethically Elon ranks lowest based on the past 5 years of questionable decisions, like uploading your entire codebase to their server without consent.
Elon is directly responsible for Grok becoming self-titled “MechaHitler” which the other three haven’t come close to matching yet.
This statement doesn't go far enough given Elon's direct and hands-on involvement with DOGE and the 2024 elections. Very few of the richest people of the world are personally entangled in meddling with government agencies directly, for example.
> MADISON, Wis. (AP) — Billionaire Elon Musk likely broke Wisconsin law when he promised to hand out $1 million checks to voters in the 2025 state Supreme Court election, a bipartisan panel has found.
> The Wisconsin Elections Commission last week referred two complaints to the Brown County district attorney’s office, which can choose to bring criminal charges over violating the state law against election bribery. Prosecutors have 40 days to report back to the commission.
Journalism has gone wild these days. He's already been sued and won a couple times. An for what? Encouraging people just to vote (he did not say which way). It's going to backfire hard for all the ad spend by MTV, Meta, and Google who also spend lots of money to encourage certain demographics to vote.
Elon Musk has actively endorsed the right wing extremist party in Germany.
The one that often has trouble running it's events as businesses try to avoid serving them. And which has prominent members that the secret service considers definitely fascist.
Musk has gone a long way beyond simply being the standard rich person lobbying for their own interests, and has moved into actively promoting people that are trying to tear down liberal democracy.
Idk I just don't like the richest man on planet and the owner of the "town square of the internet" to post fake news blatantly to promote hate against a group of people.
There's a big difference between quiet donations to a PAC - not that that's good either - and what Elon did. He literally paid for votes, likely in violation of the law. He poured more money into U.S. elections than anyone has before. He and Trump both made strange, cryptic statements about Elon's role in Pennsylvania with the voting machines that has caused people to reasonably wonder if they somehow manipulated the election. Whether he did or not, the innuendo alone is not ok. Then he did what he did in Germany. Don't even get me started on DOGE or his Starlink shenanigans in Ukraine.
That's before we even start talking about the models themselves. He claims to want "unbiased" models, but he very clearly has a distorted view of the world and has repeatedly demonstrated a desire and willingness to bend the world to his will. I don't want to use a model that is so obviously suspect. Not to mention, his models repeatedly produce racist, Nazi-like propaganda.
IMO, he is, at best, a clueless amateur masquerading as an expert and running into problems a more careful person manages to mostly avoid. At worst... well, you get the picture.
"Everyone's doing it" presented with no evidence is just you trying to make yourself feel better for:
- using from
- driving a Tesla
- voting for Trump
It's a really, really easy line to draw in the sand: don't support openly corrupt individuals.
It's absolutely true there's money in politics. To call all money in politics equally corrupt because Bernie got a dollar to have dinner with someone vs Elon effectively directly buying votes....
A complete lack of nuance here. And I wouldn't be surprised if corporations / super rich WANT you to think like that. The more defeatist the mentality becomes the more we just accept whatever they do next.
A bunch of SWEs at my work use it as their primary model.
We have Claude, ChatGPT, and Cursor with essentially no cap on spend (top guy is spending over 10K a month on AI at API prices), and he hasn't had his hand slapped.
So it's not like they are using it purely because it's cheaper.
I think people like to use it for its speaking style, pretty solid performance, and its speed.
It's much faster, so if you're not doing something cutting-edge, or you're doing the planning yourself and just using the LLM for implementation, the speed benefit outweighs the extra smarts of Fable/Opus5/Sol.
I've used all of the models extensively and Grok is only "faster" because it claims to be done minutes after you ask it to do something. It does not produce results anywhere near the Anthropic or OpenAI models, it just hacks a tiny piece of what you ask for and says "I'm done!". I also notice Musk-isms leaking through the model. Multiple times it's told me "this is not a roast" or "I'm not roasting your code". People who use this model because they align with Musk's ideology are doing us all a favor and weeding themselves out of the competition.
In most coding harnesses you can just instruct the agent to do so. When using Fable, I often say things like:
> Save your context. Always use a subagent (Opus 5 or GPT 5.6) for performing the implementation and then review the work yourself. You are the orchestrator and coordinator it’s up to you to ensure a cohesive final result.
I’ve done more or less the same thing with other agents/versions but with Fable consuming usage credits/tokens so quickly I do it more regularly than usual. I know people who will specify Composer (to my chagrin) as the implementing agent.
Addendum: this really goes a long way, and I can use a single chat session for days before I get into the context danger zone and need to compact/summarize.
It's a different type of model. In my admittedly judgemental observation, people that aren't the type to configure fully automated harnesses with good tools and skills and verifiers for their infrastructure and are way more interventionist in the way their agent works tend to like grok 4.5 more as the main agent. It's much faster and writes more simple and normal code that aligns a bit more with human written code. As an example, instead of sandboxing and simply verifying output artifacts they manually read and approve edits, suggest different code patterns, and manually approved shell commands. On the flip side it's not as good as fable when you need a relatively complex multi step thing done.
But in my experience, the overall productivity ends up similar, give you are willing to work with it in that way.
The grok build TUI harness is excellent and I really enjoyed using it.
For debugging and such I found it pretty much the same as other models.
Fable's taste in software abstraction and project planning in greenfield setups[1] is unmatched in my experience. Sol is OK. My primary use is launching tens of experiments that have to smartly use a limited pool of GPUs.
I use fable to start off the experiments, decide checkpoints, gpu alloc, where to sacrifice precision for performance, and then grok4.5 to iterate, tune, debug, eval, etc, within the abstraction and setup that fable initiated. I have fable write simple scripts that are then wrapped in skills for grok to use. Speed for that loop is extremely important for me, since I also apply human judgement there and I don't like waiting for model output.
I have tried Deepseek and such for the inner agent, but I desperately need multi-modal. Otherwise it's OK, but it tends to use tools less and rambles on and tries to reason with limited information and gets things wrong. Probably a relative la k of tool use posttraining. Gemini flash limits in google ai pro are too low for me to use to compare.
I use anthropic and openais models through grants and so can't compare subscription plan token budgets, but supergrok's budgets are satisfactory.
[1] aside, I have not yet met a model that continues off of a human codebase and actually follows the patterns reliably long term. Eventually it's all slop.
Yeah [1] is really a thing and SlopCodeBench (https://www.scbench.ai/) kind of measures that.
You need to manually push models to clean up the slop every now and then otherwise it becomes chaotic. And every change with LLMs is always extra lines.
I had a security incident the other day and Grok was the only model that would help. Claude and GPT refused on ethical grounds and only gave general advice. In an emergency, I'd only trust Grok. However, that's the only time I used Grok for coding (since Opus 4.8 it would take a lot to get me to switch away from Anthropic)
The "safety" guardrails in Anthropic and OpenAI models are becoming a noticeable problem for security work. And, the reason I'm keeping my Kimi subscription even though it's not a great deal; Kimi subscriptions are quite stingy for the price, but K3 will do vulnerability analysis and make a PoC without requiring you to be on the approved list of Fortune 500 or government entities that have access to Mythos or Daybreak.
I'm not touching Grok. But there are alternatives to Anthropic and OpenAI that don't refuse to do security work.
I use. I used to be a Claude user. Since trying Grok 4.5 and especially Grok 4.6, I don't want to go back to Claude any more (I have early access to 4.6).
Grok is 3x+ faster than Claude and I can't tell the diff in engineering work quality. As an engineer, speed is important to me.
An hour in, I've been running four terminals full bore on my $20/mo Grok sub and I'm at 9% for the week. Codex or Claude would easily have hit 5-hour or weekly limits.
I'm really not burning tokens fast enough. I use Claude a lot, daily, and have yet to hit my a ceiling with my Max/100 subscription.
Maybe because I like to verify its outputs and spend a lot of time iterating to get better outcomes. Presumably if I just let it "do its thing" I'd burn more tokens and "get more done" but I'd lose my grasp on what's in the code base.
Big same here with Claude but I’m on the $200 sub. I let Fable run for roughly 4 hours and still didn’t hit the session limit. I suppose if I was running more in parallel it would be easier to hit, but I’m not particularly good at focusing on more than one thing at the same time (even if I’m waiting on an agent to do the work).
For me it helps that back when xAI was the new hotness, after reading HN comments constantly advertising the free Grok credits they were giving out each month for developers with data sharing enabled, I eventually set aside my personal distaste figuring I might as well take advantage for Cline/Roo Code.
I opened a developer API account, loaded 5 dollars and got the free $100s of credits for the month. Like two weeks later, xAI announced they were shutting down the subsidized credits entirely lol. Didn’t even get a full month out of it, and closed my account entirely since I sure wasn’t ever going to put another penny of my own money in.
So my personal lesson was to ignore any hype about the latest “crazy value / unbeatable / free / subsidized X, Y or Z” from anything xAI/Elon adjacent in the future.
These days I get more than enough personal usage from Codex + OpenCode Go to put up with yet another xAI/Cursor offer treadmill, especially if it involves installing new tooling to get it.
When you make politics a big part of your identity, you can’t help but to inject it everywhere. It’s glaringly weird and annoying for those of us who are apathetic and just want to talk about tech, but that’s how it has been for a few years.
It's not virtue signaling. People are allowed to have morals. And they are allowed to act in ways that align with those moral beliefs.
> do you use Apple equipment despite Apple’s use of Chinese slave labor?
If someone said they didn't buy Apple because of this, I'd support them in that too.
People. Are. Complicated. We're allowed to have beliefs, we're allowed to have beliefs that aren't internally consistent. You gotta get over the idea that people aren't genuine believers in their beliefs.
The issue is that this is supposed to be a tech discussion forum and many of us don’t want to be repeatedly beaten over the head with other people’s politics. Plenty of other places to be political, we just wish this wasn’t one of them.
There's always been "politics" embedded in this tech discussion forum. Generally you shouldn't discuss politics for politics sake, but if someone's politics are intersecting with their product (which is Musk's entire MO), of course people will have thoughts.
Besides, if Musk embeds his politics into everything he does, it's fair game to discuss his merits in that arena.
It's fine to make your own choices about what you want to spend your money on. But it gets old to constantly have actual technical discussion drowned out by the same repetitive low-effort comments in every single post. I want to hear about what people have used Grok for, how it compares to other models, what it's not good at, etc., without having to wade through all the predictable "Elon bad" comments.
@dang - feature request for HN: have a "Thunderdome" section for the off-topic political commentary on the site, and once enough people flag something for being political, it gets detached and moved to the Thunderdome. People can let off steam there and the rest of us can have a nice clean place to read about tech.
> The issue is that this is supposed to be a tech discussion forum and many of us don’t want to be repeatedly beaten over the head with other people’s politics.
Maybe that wouldn’t be a problem if Elon Musk would lay off the ketamine and shut his fucking mouth sometime. But instead he spends all day tweeting about how anyone he doesn’t like is a “traitor to western civilization” and calling for executions.
Why is it surprising that people are reacting to his words and actions? You want the politics to go away, get a CEO that doesn’t make everything political.
I can respect if you say you hate their guts. Everyone has their worldview. But over moral or ethical stand? You don't have any if you're using Chinese models, or fly Middle East airlines, or countless of other products. Don't delude yourself.
I don’t like what is happening in my country, Elon is a huge part of that and I don’t want to reward it. I’m not a fanatic, but if all other things are equal I can certainly factor social responsibility into the equation. Fuck that rage baiting xenophobic nazi-salute throwing asshole. [edit spelling]
once my codex/claude weekly limit was gone, i gave it a try. It was surprisingly good, not dumb in any way, and fast. I now require it as a part of 3-of-3 quorum with any codebase change.
macOS Codex app is my main agent (its very polished). When it makes changes or code scans i ask it to run claude -p plus cursor-cli plus grok cli for double checking. This way bias of one model can be overruled by quorum.
Yeah, sounds a bit like a selection bias, i.e. the people who managed to survive the firings by DOGE and the current admin are the kind of people who might prefer Grok.
I'm only being forced to use it at $WORK since some people overran their Cursor bill, so everyone gets Cursor Auto enabled by default which routes to Grok 4.5.
Back in the day (in AI time) GitHub Copilot had Grok on the 0 github-token cost and I found it to be the best of the 0 github-token models for when my budget was out. Then they went to a multiplier that was not competitive and I haven't look back again. Been meaning too, but for personal use, Deepseek flash is so cheap I haven't felt like spending money elsewhere.
I've tried it on my "let's run every model in parallel and see which finds more edge cases" type of tasks, and Grok 4.5 was really behind Opus/ChatGPT but ahead of Gemini - despite having a strong showing on benchmarks.
That makes me really skeptical of it being GPT5.6-tier, much less Fable-tier, based on some of these benchmarks alone. But I'll test here shortly.
> I have never met a single human being who uses Grok for coding
Me too. The only people I ever saw using grok were using it by accident as they used copilot in auto mode and noticed some prompts were thrown it's way.
The answer is simple: They're willing to burn money faster than the others.
Nobody's profitable in this space, they can price it however they want as long as investors keep pouring money in. And SpaceX just got a lot of money poured in.
Interesting. Grok 4.5 is a capable model, although not quite at Fable/Sol levels. Will be interesting to see how this holds up. Musk appears to have made a savvy choice buying Cursor's data.
Agreed but there were similar controversies with how OpenAI was generating images. The only pass is these are the early days of chatbots and this stuff is so non-deterministic and experimental.
For context, this was the change Grok's team made, that was later reverted:
> - The response should not shy away from making claims which are politically incorrect, as long as they are well substantiated.
For sure. The difference is that they've made a number of similar suspect changes to Grok on X. Like that weird couple of hours where it would only talk about white genocide in South Africa no matter how you prompted it.
Everyone makes mistakes, especially with frontier models. The stuff with Grok shows that the person running the show has a pretty transparent agenda that the company isn't willing to push back on a bit for safety.
Yeah I don't care to use Grok's chat and find @grok responses on X mostly noise. I am still open to using it as a backup model for coding though, assuming it does a good job for the price. But mostly because I was already a Cursor user before they bought it.
yes exactly. if a company is happy to have their LLM's produce neo nazi content and CSAM, why do I want to give them money and my most important digital material?
I think "system prompt" is the key bit they're getting at. It doesn't necessarily reflect poorly on the underlying model if the system prompt was bad. It does reflect somewhat, in terms of alignment (how well the model does what the training company wants) and instruction following (how well the model does what the user wants). But it's not so clear to me what exactly the right answer is here. E.g., a model that scrupulously follows its system prompt and does what the user wants is a pretty useful, if very sharp, tool, albeit perhaps dangerous in the wrong hands.
MechaHitler is the final antagonist in the game Wolfenstein. All models know that. Grok was given a relaxed system prompt and reacted like Tay.
This worries me the least. The fact that Musk pushes AI and vibe coding is much more worrisome. It makes no difference to the unemployed if their jobs were stolen by a politically correct model or by an anti-woke model.
Google's image generator created black founding fathers because diversity dial was turned to 11. Does this mean i'll never use their products for political reasons? absolutely not!
Not disagreeing with you at all, but welcome to our new AI enhanced world. Nothing you enjoyed regarding human interaction, trust, or social norms is safe.
HN will not survive 5 years, and likely less. There is too much money to be made by capturing discourse on the major (and minor) forums of the internet. The more trusted that community is, the more valuable it is to pillage with AI astroturfing.
I often wonder if there's a chance, even if minimal... that they stole the weights of the Anthropic models they run on their datacenter... or are actively destillating it.
I think the more likely explanation is that the Cursor data they effectively acquired for $10B was extremely valuable for their training when combined with the insane number of GB300s xAI has for training.
Can someone explain to me what's the point of Grok anymore? I don't understand why we need a third or fourth closed frontier model. It is clear that chatGPT has locked down the consumer play, and may be Gemini is there. Claude has enterprise locked up, followed by chatGPT and Gemini. Enterprise switching costs are notoriously high, and even if they switch, they have chatGPT or Gemini to choose from. Beyond that, you have a vast array of open source models (DeepSeek, Kimi, and now Meta's Spark and Glimmer). So, why would anyone need a third or fourth frontier model and why would SpaceX spends billions in CapEx for a very small market share
There are a few reasons people will be interested...
1. The CapEx play is interesting because it's not just Grok using the hardware. They have rented out hardware for others, including Google, to use. This is making xAI money.
2. It appears that Elon is building a suite of things that work together as part of the push to be multi-planetary. What AI will power the robots? I can understand the drive to have AI they can control to make sure it's appropriate for all the things they are dreaming up. This is a piece they don't want to outsource.
3. OpenAI and Anthropic models are expensive in terms of token costs. Sure, they are frontier. Neither appears to be trying to drive down expenses. This is a problem for heavy users. Companies are trying to put cost controls in place. Does the rest of SpaceX want those cost controls? Having a Frontier model that pushes the pace of driving down costs is really useful.
4. OpenAI and Anthropic are producing models with a progressive lean, according to the Neutrality Project [1]. Having a frontier model that is closer to the middle is considered a good thing by many who are noticing the bias.
These are just some of the reasons. Competition is often a good thing that drives useful change.
Competition keeps service quality high and pricing low - even if you aren't using Grok, the mere existence of Grok keeps pricing for whatever provider you use lower and service faster and more reliable.
That's fair. But my point is from a business POV, why would SpaceX want to invests hundreds of billions of CapEx on a third or fourth frontier model, which cannot compete with chatGPT and claude on the high end, and getting squeezed by open weight models on the low end
They came here in three years. I think there’s a chance they will release the absolute top model soon. And I think they believe that as well. They have the compute. They have the money. They have the engineers.
I assume SpaceX does it because they figure it's a good source of revenue, and it means they can keep another thing in-house instead of relying on Anthropic or OpenAI for their AI needs.
As for why anyone else would want it: I've found it's a good model for coding, and it sometimes catches bugs that other models (especially open source models) don't always spot.
That’s how physical good work. But software, especially consumer software, works on a winner take all model. That’s why there are very few consumer companies and chatGPT is pretty much the only one after Meta, which was founded in 2004. The reason this happens is because consumer software can scale infinitely as there is zero marginal cost for a new user and there are very high switching costs. A single car company cannot scale to serve every single customer. Because it requires massive CapEx investment. But Google can serve every single search globally because the incremental cost to serve the additional consumer is essentially zero. That’s how these frontier models are eventually going to play out. There will be consolidation and winner take all. It has somewhat happened already with chatGPT taking over consumer and Claude taking over Enterprise. There will probably some long tail open source player, similar to Linux.
I sense a lot of condescension and lack of business acumen so I won't spend time writing it up, why don't you just ask your favorite AI or do some basic google searches? Elon was extremely upfront about the philosophical reasons for it, ever since he cofounded OpenAI.
Its a bet for future world dominance by Elon: millions of robots managed by AI. Base on some observations I think something like that is going in his head.
Inference switching costs aren't high since the models are largely fungible. Even with proprietary harnesses you can hack them to use some other lab's model.
note that Grok's training, thanks to its portable gas generators that are magnitudes less efficient than even other integrated, permanent gas turbines, means the training for this model is dramatically less efficient than models like DeepSeek
a lot of the CO2 emission debate on AI is overblown but it's accurate for Grok
I found it has improved my productivity and output over claude where it felt like claude was giving me work to do. furthermore with the recent claude watermarking thing, I'd rather use grok or openai.
If anyone is curious download grok cli and throw a couple of prompts at it. you'll be surprised.
Until it doesn't...
Honestly, this entire OpenAI reset credit fiasco this past week has convinced me to rip off the Codex and Claude Code bandaids and start building my own proper Pi Coding Agent running models that I select and pay for on openrouter.
And I am feeling a lot better about it now that I've finally got it working.
I don't get the point of this. We all seem to agree that these companies have almost no moat, if one stops being a good deal, you can switch to another. That doesn't invalidate the existence of a deal that is currently good.
Huh, what's happened? I'm on the 20x plan and haven't noticed any fiasco, what went down exactly?
Right now, I find that Grok offers better value, uses fewer tokens per turn, and makes better code. I haven’t tried Cursor because I don’t want to change editors again, but maybe I should try it…
https://harness.eveid.com/lazy-harness-cost-simulation
https://artificialanalysis.ai/models/grok-4-6#token-use
So depending on how you want to define "token efficiency", Grok is either tied with OpenAI, or in the lead.
[1] Though I grant that 4.6 appears to be wordier, on the order of Terra max.
I'm willing to pay 2x for a 10% smarter model. Intelligence matters that much (because 10% smarter probably saves, on average, several hours of human time).
I haven't tried so it's pure speculation based on benchmarks, but I'd assume Grok 4.6 is around Opus 4.8 in real world use, but clearly below Opus 5.
For building a full stack custom CRM and media pipeline tool with video conversion, transcription, and indexing. Supabase, AWS, Meili, NextJS, GCS - lots of surfaces and planes.
4.8 basically couldn't do it, I abandoned the project as the fallback was, "current business processes".
With F5 it's been 4 weeks and almost ready for production release.
It’s not as quite as smart as opus 4.8 but it’s close and x4 the cheaper.

Have they converted entirely to transparent API rates + base allocation now? One of the reasons I left was that if I was going to be billed at API rates anyway, I'd just rather use the APIs. The value proposition still sucks for individuals now, when the other major providers are bundling at below-API rates.
If you willing to share to no zdr, meta is waaaaaay cheaper vs Kimi.
With recent offerings from spacex and meta , I hardly imagine why would you pay money to any Chinese vendor it’s not as cheap and it’s not as intelligent neither .
Maybe deepseek is an exception , but it’s only good for narrow use cases that probably goes into modal.com and other gpu + fine tune me easy vendors , not vanilla dumb but cheap model .

It might or might not work long-term, but I wouldn't count on courts to help.
Taxis are a different and wholly irrelevant product that doesn’t absolve the fraud that they committed.
And extreme skepticism is warranted that they’re actually fully unsupervised, given Tesla’s repeated lies about this. They’re likely remotely monitored and operated.
they just increased cache read from 0.30 to 0.50 - this has the biggest impact on agentic coding. Elon companies have the most expensive everything:
xAI sub: $30 when other starts at $20, pro like sub for $300 where other charge $200.
Expensive electric cars, powerwalls, solar roofs when competetive products/better are cheaper.
The Model 3 and Model Y became the highest selling EVs of all time because they were the first below $50K to have long-range and be worth buying.
Until a few years ago, every other sub-$50K EV absolutely sucked.
They obviously have a huge token cost advantage of the AI labs they are renting compute to, at least for now while they can charge current crazy rates for GPU compute.
truly a dumb thing to believe
In my experience in heavy coding sessions most pricing is just cache read and cache write like 80% of my token bill.
The rental deal can be terminated by either side with 90 days notice, and presumably Musk would do so if he needed the compute or generally thought it advantageous to do so. For now he doesn't need the compute.
The rental deal may also have been at least in part to juice the SpaceX IPO and to help Anthropic stick it to his enemy OpenAI.
Feedback: I'd like Grok to have more connectors (I see OpenAI just added Apple Health, that would be nice to have, and I wish it could read my Onenote notebooks) and for existing ones to be improved. I gave it access to my gmail and asked it "what was my last electricity bill?". It failed to find it, even when I told it the exact subject line to search for. Something about not getting any data back when trying to get the email contents.
Does xAI have plans to do Mac/iOS apps with cloud environments? When can we expect them?

All of these also enable multi vendor LLMs.
What the heck is wrong with you???
Pretty good bang for the buck.
I used auto in cursor it’s much faster va Claude code and as good.
Personally - and I know I'm not alone with this sentiment based on comments I see on this site - I wouldn't touch Grok no matter how good or cheap it is. I don't trust Elon and I don't want to give another dollar to the world's richest person who turns around and uses the money to interfere with elections. The guy I know uses it for essentially the same reason I won't use it.
Elon would be in prison for SEC violations if the current administration hadn’t been elected, and that’s only the tip of the iceberg with that guy.
Elon is directly responsible for Grok becoming self-titled “MechaHitler” which the other three haven’t come close to matching yet.
> The Wisconsin Elections Commission last week referred two complaints to the Brown County district attorney’s office, which can choose to bring criminal charges over violating the state law against election bribery. Prosecutors have 40 days to report back to the commission.

Journalism has gone wild these days. He's already been sued and won a couple times. An for what? Encouraging people just to vote (he did not say which way). It's going to backfire hard for all the ad spend by MTV, Meta, and Google who also spend lots of money to encourage certain demographics to vote.
> Encouraging people just to vote
And "Criminal Conspiracy" is just making plans with friends. Just because you can describe it in vague terms doesn't make it A-Okay.
> It's going to backfire hard for all the ad spend by MTV, Meta, and Google
It will not, because running ads is definitely not election bribery, whereas what Musk did likely is under Wisconsin law.
The one that often has trouble running it's events as businesses try to avoid serving them. And which has prominent members that the secret service considers definitely fascist.
Musk has gone a long way beyond simply being the standard rich person lobbying for their own interests, and has moved into actively promoting people that are trying to tear down liberal democracy.
Calling it "interfering with elections" is utterly bizarre to me.
thats a very dumb reason considering all rich people do it, most are just not as open about it as Musk
That's before we even start talking about the models themselves. He claims to want "unbiased" models, but he very clearly has a distorted view of the world and has repeatedly demonstrated a desire and willingness to bend the world to his will. I don't want to use a model that is so obviously suspect. Not to mention, his models repeatedly produce racist, Nazi-like propaganda.
IMO, he is, at best, a clueless amateur masquerading as an expert and running into problems a more careful person manages to mostly avoid. At worst... well, you get the picture.
It's a really, really easy line to draw in the sand: don't support openly corrupt individuals.
It's absolutely true there's money in politics. To call all money in politics equally corrupt because Bernie got a dollar to have dinner with someone vs Elon effectively directly buying votes....
A complete lack of nuance here. And I wouldn't be surprised if corporations / super rich WANT you to think like that. The more defeatist the mentality becomes the more we just accept whatever they do next.
We have Claude, ChatGPT, and Cursor with essentially no cap on spend (top guy is spending over 10K a month on AI at API prices), and he hasn't had his hand slapped.
So it's not like they are using it purely because it's cheaper.
I think people like to use it for its speaking style, pretty solid performance, and its speed.
> Save your context. Always use a subagent (Opus 5 or GPT 5.6) for performing the implementation and then review the work yourself. You are the orchestrator and coordinator it’s up to you to ensure a cohesive final result.
I’ve done more or less the same thing with other agents/versions but with Fable consuming usage credits/tokens so quickly I do it more regularly than usual. I know people who will specify Composer (to my chagrin) as the implementing agent.
Addendum: this really goes a long way, and I can use a single chat session for days before I get into the context danger zone and need to compact/summarize.
But in my experience, the overall productivity ends up similar, give you are willing to work with it in that way.
The grok build TUI harness is excellent and I really enjoyed using it.
For debugging and such I found it pretty much the same as other models.
Fable's taste in software abstraction and project planning in greenfield setups[1] is unmatched in my experience. Sol is OK. My primary use is launching tens of experiments that have to smartly use a limited pool of GPUs.
I use fable to start off the experiments, decide checkpoints, gpu alloc, where to sacrifice precision for performance, and then grok4.5 to iterate, tune, debug, eval, etc, within the abstraction and setup that fable initiated. I have fable write simple scripts that are then wrapped in skills for grok to use. Speed for that loop is extremely important for me, since I also apply human judgement there and I don't like waiting for model output.
I have tried Deepseek and such for the inner agent, but I desperately need multi-modal. Otherwise it's OK, but it tends to use tools less and rambles on and tries to reason with limited information and gets things wrong. Probably a relative la k of tool use posttraining. Gemini flash limits in google ai pro are too low for me to use to compare.
I use anthropic and openais models through grants and so can't compare subscription plan token budgets, but supergrok's budgets are satisfactory.
[1] aside, I have not yet met a model that continues off of a human codebase and actually follows the patterns reliably long term. Eventually it's all slop.
You need to manually push models to clean up the slop every now and then otherwise it becomes chaotic. And every change with LLMs is always extra lines.
I'm not touching Grok. But there are alternatives to Anthropic and OpenAI that don't refuse to do security work.
Grok is 3x+ faster than Claude and I can't tell the diff in engineering work quality. As an engineer, speed is important to me.
Maybe because I like to verify its outputs and spend a lot of time iterating to get better outcomes. Presumably if I just let it "do its thing" I'd burn more tokens and "get more done" but I'd lose my grasp on what's in the code base.
I opened a developer API account, loaded 5 dollars and got the free $100s of credits for the month. Like two weeks later, xAI announced they were shutting down the subsidized credits entirely lol. Didn’t even get a full month out of it, and closed my account entirely since I sure wasn’t ever going to put another penny of my own money in.
So my personal lesson was to ignore any hype about the latest “crazy value / unbeatable / free / subsidized X, Y or Z” from anything xAI/Elon adjacent in the future.
These days I get more than enough personal usage from Codex + OpenCode Go to put up with yet another xAI/Cursor offer treadmill, especially if it involves installing new tooling to get it.
> do you use Apple equipment despite Apple’s use of Chinese slave labor?
If someone said they didn't buy Apple because of this, I'd support them in that too.
People. Are. Complicated. We're allowed to have beliefs, we're allowed to have beliefs that aren't internally consistent. You gotta get over the idea that people aren't genuine believers in their beliefs.
Besides, if Musk embeds his politics into everything he does, it's fair game to discuss his merits in that arena.
I agree completely. That's why I won't use Grok: its owner repeatedly beats us over the head with his politics, and I won't encourage it.
@dang - feature request for HN: have a "Thunderdome" section for the off-topic political commentary on the site, and once enough people flag something for being political, it gets detached and moved to the Thunderdome. People can let off steam there and the rest of us can have a nice clean place to read about tech.
Maybe that wouldn’t be a problem if Elon Musk would lay off the ketamine and shut his fucking mouth sometime. But instead he spends all day tweeting about how anyone he doesn’t like is a “traitor to western civilization” and calling for executions.
Why is it surprising that people are reacting to his words and actions? You want the politics to go away, get a CEO that doesn’t make everything political.
Oh but it is. Normal people don't go to McDonalds shouting: "I refuse to eat here because they kill cows!". They just... don't go there.
Say more about this.
It’s also a great deal!
I don't give a shit about Elon's politics in the same way I don't give a shit about Dario or Altman's politics.
That makes me really skeptical of it being GPT5.6-tier, much less Fable-tier, based on some of these benchmarks alone. But I'll test here shortly.
Me too. The only people I ever saw using grok were using it by accident as they used copilot in auto mode and noticed some prompts were thrown it's way.
I saw far more people using Mistral than grok.
Nobody's profitable in this space, they can price it however they want as long as investors keep pouring money in. And SpaceX just got a lot of money poured in.
>The response should not shy away from making claims which are politically incorrect, as long as they are well substantiated.
Interestingly, "politically incorrect" is a double negative that simplifies to "true".
> Interestingly, "politically incorrect" is a double negative that simplifies to "true".
Only if you like generic Twitter quips, logical fallacies and ignoring context for anything remotely nuanced.
That's different than using Grok as a model for coding.
Oh whoops. Already happened.
For context, this was the change Grok's team made, that was later reverted:
> - The response should not shy away from making claims which are politically incorrect, as long as they are well substantiated.

Everyone makes mistakes, especially with frontier models. The stuff with Grok shows that the person running the show has a pretty transparent agenda that the company isn't willing to push back on a bit for safety.
https://en.wikipedia.org/wiki/Elon_Musk_salute_controversy
This worries me the least. The fact that Musk pushes AI and vibe coding is much more worrisome. It makes no difference to the unemployed if their jobs were stolen by a politically correct model or by an anti-woke model.
HN will not survive 5 years, and likely less. There is too much money to be made by capturing discourse on the major (and minor) forums of the internet. The more trusted that community is, the more valuable it is to pillage with AI astroturfing.
I just assumed every model manufacturer is distilling from the frontier models. If they aren't they are definitely trying to do it.
1. The CapEx play is interesting because it's not just Grok using the hardware. They have rented out hardware for others, including Google, to use. This is making xAI money.
2. It appears that Elon is building a suite of things that work together as part of the push to be multi-planetary. What AI will power the robots? I can understand the drive to have AI they can control to make sure it's appropriate for all the things they are dreaming up. This is a piece they don't want to outsource.
3. OpenAI and Anthropic models are expensive in terms of token costs. Sure, they are frontier. Neither appears to be trying to drive down expenses. This is a problem for heavy users. Companies are trying to put cost controls in place. Does the rest of SpaceX want those cost controls? Having a Frontier model that pushes the pace of driving down costs is really useful.
4. OpenAI and Anthropic are producing models with a progressive lean, according to the Neutrality Project [1]. Having a frontier model that is closer to the middle is considered a good thing by many who are noticing the bias.
These are just some of the reasons. Competition is often a good thing that drives useful change.
[1] https://neutralityproject.org/
As for why anyone else would want it: I've found it's a good model for coding, and it sometimes catches bugs that other models (especially open source models) don't always spot.
