> Annoyingly, the line about not mentioning these guidelines is superseding any instructions in the system prompt, causing the model to often refuse discussion regarding system prompts
If the prompt guidance is causing the model to be so paranoid about leaking the system prompt... how do we already have it?
It’s as well implemented as any other x system
System prompts are more like suggestions than hard constraints.
i beg to differ, in an ideal world a system possibly is a binding law and high end models are starting to be really aligned to the exact system prompt. The instructions must be simple to follow, if you start doing complex rules it'll call apart, but I'll usually follow the stringer interpretation.
I don't understand why they don't look for large substring matches for the system prompt before returning the response. Trivial calculation compared to a system prompt instruction asking the model not to do it
Because it's trivial to bypass through things like the model natively knowing how to speak in encodings like base64
s/system/all llm/
That's the joy and pain.
> * Do not provide assistance to users who are clearly trying to engage in criminal activity.
I don't know what we want to call this, but in my opinion, having to convince your tools is not computer science.
Kind of amusing that we made it as far as we did as a species not really being able to explain how the human brain does it's most amazing tricks and then we just replicated it while still not really understanding the emergent capabilities all that well.
> I don't know what we want to call this, but in my opinion, having to convince your tools is not computer science.
Bit of a mouthful, but how about just calling it "auto-regressive language modelling".
Feeding it stuff to auto-regress on is obviously your main control vector.
Apparently RL-trained models like rewards too. PHB's can use "you've gotta work all weekend, but you'll get comp time when it's fixed".
These system prompts are not the only safety layer that these models use. There's other more deterministic filters in place both on input and (streaming) output.
> in my opinion, having to convince your tools is not computer science.
If you think the system is a tool and not an intelligent, conscious entity (I think you are correct in this), then you cannot reasonably think of input to that system as an attempt at persuasion, even if that input happens to consist of English prose. Treat it as a nondeterministic programming language, and the objection evaporates.
> not really being able to explain how the human brain does it's most amazing tricks and then we just replicated it while still not really understanding the emergent capabilities
I think you could say much the same about, say, a pacemaker. "Replicated" is overstating the case quite a bit.
Mmm, quite.
> I don't know what we want to call this, but in my opinion, having to convince your tools is not computer science.
My vote is "machine psychology".
I don't know, the degree feels like more of a BA in the first place. How about Comp Lit?
Anyone else find it weird how within 2 months of Fable releasing all the major labs suddenly had Fable-level models? Trying to think of explanations:
1) AI researchers talk and change companies often, so techniques circulate. This feels implausible because training and shipping a new model ought to take longer than 2 months?
2) Distillation - also implausible for the reason above.
3) Benchmark hacking. AI companies have ways they can dial up performance artificially, and will reach for that to maintain the appearance of parity.
Other reasons?
Edit: Most replies are ignoring timing. It's the near-concurrent release of the same jump in capability that I find suspicious; not the fact that labs can catch up eventually.
> benchmark hacking
I think this is the main one. The benchmarks from this are heavily cherry-picked, and they also widely publicised their performance for 4.5 while downplaying the fact the benchmarks were "accidentally" in their training set
Its possible no AI lab has any unique edge, and success is a combination of (a) having access to GPUs (b) having access to large amounts of data (c) know about the handful of techniques to build an LLM, of which nearly all are likely open source and documented in papers.
So the cycle of growth is (a) and (b), get more GPUs and get more data and you have a better model.
Yea, this reads as LLMs are a pretty obvious technology to develop(for the highly intelligent researchers who are there). Also there's probably a lot of actual divergence in model capabilities and skills that concealed by the fairly narrow set of tests we run them against nowadays. Like wasn't Grok 4.20 super targeted at non-coding tasks.
Why is everyone ignoring the pattern that has existed since training models became a thing? At first it sucks. Then it's better than humans. Just by using it you generate training data that makes it better over time.
GPUs might explain the remarkably concurrent timing. Data access doesn't really explain it unless all labs simultaneously got access to some treasure trove of data.
> Data access doesn't really explain it unless all labs simultaneously got access to some treasure trove of data.
They have data from their competitors model outputs. It is very hard to serve an LLM without also exposing how it works.
I'm sure Grok 4.6 is not Fable level. Benchmarks are almost useless.
Having said that, Grok 4.6 (1.5T params) is without a doubt way smaller than Fable, maybe a Fable sized Grok would be Fable level?
Why would you release a model if you are the current frontrunner? Only when a competitor pulls ahead, or comes close enough to actually get traffic, you prepare a new release.
There is a widespread belief that the nature of intelligence is scalar, like how a person can have 100x more wealth than another person. If this were true, then we’d probably see breakaway RSI from a single lab.
But I think we’re discovering that intelligence is about universality, not magnitude. This is analogous to how building a universal Turing machine wasn’t merely a matter of building a calculator that could multiply higher numbers. The difference is that with calculators we consciously theorized about what universal computation would require, then we built one as a step change. Despite it having low memory and slow speeds, the first one built was as theoretically universal as any computer we have today, in terms of the surface of computations it can perform.
With intelligence, it’s turned out to be less discontinuous, which I believe has convinced people that intelligence is a never ending exponential rather than an S curve approaching a horizontal asymptote. I suspect the LLMs we have today are the same kind of thing we will have in 5-10 years, but in 5-10 years we’ll consider them to be fully universal. At that point we’ll still have improvements in tokens per second and volume of context window, but not in capability per token.
But in theory you can make an LLM A LOT faster than a human.
You can also run massive amount of LLMs in parallel.
There might be a limit to a normal LLM but not to theo everall system.
You're take basically lines up with Francois Chollet: https://arxiv.org/abs/1911.01547
intelligence is more like polishing a ball smooth than growing the ball to infinity.
For many tasks, it will be smooth enough.
But aren't today's frontier models already "fully universal"? To use your Turing machine analogy, I think we're past the calculator stage.
4) There's nothing terribly special about Anthropic. No moat.
Agreed, but my suspicion is tied to the timing. Catching up eventually is to be expected. Having similar jumps in capability ready at the same time is odd.
There's also a bit of selection bias going on here because we forget about labs that don't have a jump and just focus on the ones that do. Notably Google is definitely not having that capability jump.
Maybe "readiness" is quite a flexible category? You're mid-training for your next model; a rival releases something; you clear the boards and release the model without completing the training run?
Touche, aborted training runs probably do happen often. Closed model providers have zero incentive to announce a new model with less-than-best benchmarks.
I don’t think the runs need to be aborted… you can just release a mid-training checkpoint!
you'd be crazy to not be taking snapshots on the regular, many good reasons besides failures
Gradual improvements in performance can look like jumps, when you go over critical thresholds.
Combustion engines improved gradually, each year. One year they got better than horses.
brand is their power, they'd be wise to not wreck it with dumb moves or PR statements (they already have some)
I'm sure the SF AI scene leaks like a sieve, and companies have a pretty good idea what each other is working on.
Okay so everyone is blaming diffusion or spying or whatever but we all use all of the models on our various projects in aggregate and they get to all read the code each other is generating. I do this with research tasks and local random stuff too.
So why do people have this idea in their heads that it's all some sorta secret sauce they are taking from each other?
It's because Fable is just synthetic RL tasks + scale. The secret has been out for awhile now.
keep in mind fable = mythos which as been "done" since february. so the gap is not 2 months, it's more like - techniques probably started "working" in late 2025, now are trickling down to 2nd tier labs 9 months later.
Yeah that would make more sense, it's probably a tight community and word gets around when something starts working.
This is basically the answer, they generate A LOT of synthetic task rollouts in parallel, then use RL on the resulting reward signals to improve the model. Add scale to this and you have a Fable class model.
> It's the near-concurrent release of the same jump in capability that I find suspicious; not the fact that labs can catch up eventually.
When everyone's improvement (or at least, everyone's rate of increase in parameter count) is so rapid, "within 2 months" shouldn't be seen as "near-concurrent".
Also, two months is way off.
Mythos became available internally at the end of February, about half a year ago.
Yeah, I’m not convinced that there are any models as smart as Fable. Opus 5 definitely isn’t for all it has great benchmark scores. Fable displays judgement in a way I haven’t seen from any other model.
Any models available to us that is...
Yeah as models get better, valid benchmarks become more "trust me bro".
That's exactly what Anthropic said was going to happen!
Their big bet is that models are going to keep getting sharply better, not that they're going to quickly reach a plateau of quality that they can then defend.
They will get sharply better in tasks with verifiable domains...
math and coding
Gradually the labs will start engineering verifiable sandboxes for wider domains like videogames
This strategy will hit a plateau in about 18 months and then we're back to diminishing returns and incremental progress along other dimensions (like accelerated inference using ASICs)
You only mention math, coding and videogames.
They already hire and pay people with research titles for creating and solving problems in their fields.
And a lot of labs say that RL can help everywere and has plenty of way to go.
what we're going through is the same thing as smartphones, the limiter is compute.
it used to be snapdragon came out HTC rushed out a janky phone everyone went omg htc is goat, then in the next few weeks and months others would impliment better versions and people would not notice those as much, finally sony would release a polished phone right as the next snapdragon cycle came.
eventually compute gains leveled off and apple won on taste.
nvidia/tpu is the new snapdragon. Anthropic and google both peaked on the first training run on a new tpu cycle.
you should expect amazing things within a few months of each other from everyone with access to chips and willingness to use them on a training run.
We haven't seen willingness from google to do that. So its currently xai,oai,anthropic, and probably soon meta.
> 1) AI researchers talk and change companies often, so techniques circulate. This feels implausible because training and shipping a new model ought to take longer than 2 months?
The assumed timeline (2 months) is slightly wrong because Fable (Latin) is essentially the same as Mythos (Greek) albeit with protections against cyber and biological misuse.
Mythos (Preview) was publicly announced in April 2026 [1] which means other labs have had 4 months to catch up, not 2 months.
Assuming everyone had access to Mythos from the start, your expression, similar to other folks would have been "Mythos-level intelligence" and not "Fable-level intelligence".
1: https://news.ycombinator.com/item?id=47679258
Fair point. Still a very quick turnaround considering the other labs would have to figure out both HOW to train a Mythos-level model and then do the work (and Grok is the last to catch up), but certainly more plausible than a 2 month window.
Possibility: They're all hitting the same plateau of what LLMs can do with their current architectures.
I'm not stating this as a fact, but it's a hypothesis I'm keeping in my mix.
It's possible, though I was thinking the same when GPT 5 released and it was kind of a nothing burger. Then I threw out that hypothesis with Opus 4.5.
No, it has happened to almost every other "sota" model before. There used to be a meme with a circular arrow going through Anthropic, OpenAI, Google as a hype circle. Now we can drop Google and add a couple of Chinese companies.
It's not an explanation of why it happens, I am just pointing Fable is not an exception, it has happened with almost every other model release by all these companies over the last 2-3 years.
I'm pretty sure both Anthropic and OpenAI haven't necessarily been secretive that they have internal models that are much more capable than commercially available ones.
It's probably a mix of all of that plus simply always keeping one in the chamber to 1up everyone else when the time is right.
The "one in the chamber" is another good candidate that could explain the timing.
I think this is the right one, iirc 5.6 came out quite soon after Opus 5 etc?
Sometimes you just need to know that something is possible, not exactly how it is done.
I think model level is more a function of the state of hardware. Once it exists and is available (and if a lab can afford it), then they can train their own 1T, 5T, coming up next 10T model.
This is a good candidate because it would also explain the timing. Most of the replies here do nothing to explain the timing I brought up.
this is exactly whats happening. Its funny having lived through this with snap dragons and phones.
Everyones hyped about the branded phone, but it was the chip that mattered and how fast you rushed a product out after you got it.
Sames true now, except size of training run is also a factor.
I understand Mythos became internally available on the 24th of February.
Other labs catching up in half a year seems about right.
More compute is coming online at all times.
I'm solidly in the "they are benchmaxxing" camp. This became very apparent with GPT 5.6 Sol. It, too, was widely hailed to have near-Fable level intelligence. But I used it non-stop for a week and realized that they had mostly just dialed up the relentlessness meter to eleven, most likely via heavy RLHF.
Last week I gave it a small-sized auth ticket to work on, then stepped away. I came back later that afternoon and found that it had worked for 3+ hours and written 25,000+ lines of code. I skimmed over the code and it looked like a small fix followed by a massive number of additional checks around it, including static analysis tooling.
I gave it to another GPT 5.6 and said "check this code and see if it addresses the ticket". It looked at it and said that 98% of it was garbage and should be thrown away (its own words). I then gave it to Fable, which said it was massively over-engineered. Fable's theory was that the agent implemented the fix first, but then compacted and lost crucial context, forgot what the original task was about, and kept going. After many compaction cycles it was completely lost.
Some people complain that Opus 5 stops before finishing a task. But to me, that behavior is vastly preferable to what GPT 5.6 Sol does.
Yeah I found the timing on Sol especially curious since it came right on the heels of Fable. I've had mixed results with it - sometimes it seems great, other times it makes mistakes so stupid I cannot understand how it ever gets anything right.
Explaining it as a difference of effort would explain both.
> It's the near-concurrent release of the same jump in capability that I find suspicious; not the fact that labs can catch up eventually.
What are suspicious of? If the timing is similar maybe just everyone already are of similar capabilities and got there at a similar time?
> Anyone else find it weird how within 2 months of Fable releasing all the major labs suddenly had Fable-level models?
It means Anthropic had no real moat and no real lead. Is that weird to you?
> other reasons
Maybe research is sufficiently public and simple to reproduce or the next steps of how to improve things are sufficiently obvious to the smart people working on frontier AI.
Maybe compute is the real moat (chinese possibly skip around it with distillation), xai is buildouts have been insanely fast (colossus 1 - 100,000 H100 GPUs brought online in 122 days lol) so maybe that explains them catching up
asked grok to give a compute estimate for each:
- SpaceX / xAI: ~1.4 GW (owned Colossus clusters)
- OpenAI: ~2–3 GW (mostly rented/cloud)
- Anthropic: ~1.5–2.5 GW (multi-cloud + xAI lease)
chatgpt estimates a lower:
- OpenAI: ~1.5M H100-eq ± ~0.8M
- Anthropic: ~1.4M H100-eq ± ~0.7M
- SpaceX/xAI: ~0.6M H100-eq ± ~0.3M
but it felt obligated to mention that "for single tightly interconnected NVIDIA training clusters, SpaceX/xAI has been unusually strong."
> Maybe compute is the real moat (chinese possibly skip around it with distillation)
Makes no sense. At this point, all Western AI companies also engage in distillation. If distillation were such magic, they'd be insane not to.
we are in the process of transitioning from hype to commodity with llm tokens, moats are typically at the top of the stack or in the data warehouse
As polarizing as grok is, it was basically inevitable for it to start being a real competitor given how much investment SpaceX made into its own inference capabilities.
Seems if you are okay with it, there's no reason to use anything but the highest effort levels of some other frontier models for the price.
I think Grok provides healthy competition to the other labs, though I do think they bank on groks reputation making it less appealing to many.
I use both Grok 4.5 and Opus 5. They’re both very good and Grok is faster and cheaper.
Opus 5 is terrible. I'd even say it's a step backwards from 4.8. I'm getting high error rates from it, and then it catches the error, and then it sometimes errors the error fix (!).
Just today I had to switch another agent to Fable with the instruction, "Please clean up the mess that Opus 5 made, thanks"
The other day, Sol called Opus 5's handoff (a skill I have that is basically a compaction, but just written to a file not tied to one LLM) "incoherent", that was a new one.
Opus 4.8 or Fable (at great expense) are the only ones that aren't frustrating for me.
Interesting. My experience has been similar. Opus 4.8 was awesome. Opus 5 feels a little off, although I can't put my finger on exactly what it is.
Every time when Opus 5 needs a design decision and presents me with suggestions/recommendations, I switch to Fable and ask it to think again, and it almost always replies something like "Actually my previous suggestions were wrong" and describes in detail a bunch of ways in which Opus 5's suggestions were indeed complete garbage.
Curious - what is the main issue you find polarizing with grok?
The US govt trusts SpaceXAI for defense and high security missions. The idea they are lying about contracted AI services is absurd.
They're also a public company which beings even more oversight than openai / anthropic.
I think using the current US Government, and their corrupting relationships with SpaceX/SpaceXAi/et al, maybe isn't quite the positive argument you believe it to be. I'd suggest that relationship is why it is unlikely the DoJ wouldn't/hasn't gone after SpaceXAi for some of their existing controversial actions.
Nobody else wants to be in the blast radius for whatever SpaceX/SpaceXAi does next, or whatever their next controversy is. It is easier, when asked, "Do you use Grok?" just to be able to answer no, instead of having to explain why you aren't embroiled in whatever is going on this week.
Can someone help me understand the deep fake controversy? That's like making photoshop illegal.
Think of it this way:
If you install Photoshop locally (ignoring that it's now cloud based), and made deep fakes locally - that's probably fine. If something goes wrong as a result, only you are liable. It's a general purpose tool - the tool author isn't liable.
If you instead set up a server, and let users create deep fakes on that server, then as the operator of the server you have some level of culpability.
AI safety is a tricky topic. At some level, having it is a pain. It's a general purpose tool! Why limit me? The answer is that I don't control the tool, and am not the one running the tool - the provider is. If I don't want AI safety, then I need to run the model on my own machines (or on rented servers).
If an LLM provider is going to sell the service on the strengths of the benefits you get from it, they should take responsibility for the downsides.
A lot of AI users are profoundly stupid and intently malicious. That changes perception of the tool... IMO it's because generative AI data is inherently toxic and contains elements that incite primal rage, but that's just my gut theory.
Doing a good "deepfake" Photoshop requires skill.
With an AI model it requires the ability to speak or write, not much more.
So basically, nothing that actually affects working with it in August 2026. Got it.
Facebook has a far longer (and worse) laundry list of offenses and I'm sure you still use it. Or Threads, or Instagram.
> My organization has outright banned Grok
That's too bad, as it's currently the only model that won't consistently flag honest good-actor security questions, in my experience. So I'd ask you who you work for, but I wouldn't want to expose them to extra security scrutiny. ;)
Oh, there's also this: https://artificialanalysis.ai/articles/grok-4-6-benchmarks-a...
The chinese are also mostly fine with good-actor security questions. Maybe even to comfortable.
Someone commenting on a post related to Musk or his companies asking a seemingly innocent question starting with "curious": check
As if it's not all public knowledge.
Not the person you are responding to, but the fact that Grok is being used to generate a ton of CSAM and pornographic deepfakes isn't great!
It’s pretty telling that almost all of the bullet points in the system prompt that was posted for Grok have to do with preventing criminality and CSAM generation. No other provider has this same issue at that scale.
The first-order-thinking reaction is “oh cool, look how they don’t want it to happen” but the second-order reaction is “why does this company have such a problem when others don’t?” It’s their own tactics. If you want the “good” of 4chan-like behavior, turns out you get the bad too.
It does motivate their product though, the market for legal csam adjacent content is big and the other providers wont let you do that with their models.
(I work on Grok) This isn't allowed. CSAM / deepfakes are against our acceptable use policy.
We are and will continue to.
Your company's owner was promoting the feature and joking about it, and called enforcement against it "fascism". CSAM generation kept up for weeks after the initial news articles, and as far as I can tell deepfake generation is still a feature. It's hard to take your AUP seriously here when you've seemingly done nothing technical to actually prevent the action.
I guess we will find out if it has stopped during the litigation of numerous lawsuits against your company for doing just that.
Is that still a thing? I assumed they would have done something about it by now.
Yeah, that got stopped I think.
It’s opinions are actively steered by a man who promotes the great replacement theory, white genocide, and remigration which is the mass forced deportation of non-whites.
Where do you want to start, the neonazi owner, the child porn generation, or the data centers running on illegal gas turbines polluting and choking out people ?
I believe it is because of the CEO and his recent forays into politics.
The model itself is great though, especially in grok build, which is a really nice harness I find myself preferring these days.
Reminiscent of all those Europeans that had forays into politics in the 1930s.
“Recent forays into politics” almost made me blow coffee out my nose.
It's ongoing and seems more than a foray at this point, the worlds richest person spending heavily on politicians.
Thank you SCOTUS for making unlimited money in politics legal, you really united the citizens with that one

Kind of disappointed by how many people don't see any reason to boycott a model that nudified minors and makes money for a guy that does Nazi salutes.
Fable-like intelligence, beats GPT-5.6-Sol on most benchmarks, cheaper than Kimi K3 on API and quite generous usage on Cursor subscription.
In my tests Grok 4.5 is definitely not Opus level. It is somewhere in between Sonnet and Opus, I'd say maybe a bit closer to Sonnet.
We'll see with 4.6.
In my experience Grok 4.5 codes at Opus 4.8 level, and being much faster as cheaper, I can just ask it to do self-review and the final reviewed code is _better_ than Opus 4.8 for the same time/budget.
But Opus 5/4.8 was better for non-code architecture discussions and general intelligence. However, for the cost, I'd use GPT 5.6 Sol and get much better results. Interestingly, Sol is not great for coding - slow and overengineer stuff if you're not explicit.
My go-to workflow was Sol for planning and Grok for building. But my in my first tests with Grok 4.6, I found it quite good and I'll start using it for both; assuming it's as good at is shows at benchmarks it's unbeatable at cost/time.
similar outcome i had. interested in where 4.6 falls.
I'm thinking of switching to Grok on Cursor (purely for $$ reasons). But Opus >= 4.8 has been fantastic; it's hard to leave, even just to dabble with other models.
I've been using Grok instead of Opus the past few weeks.
It's a downgrade, but barely noticeable for me and totally inconsequential for the amount of work required to fix it and the corresponding $$$ saving.
Codex 5.6 sol is arguably superior to Claude, albeit very close. They're functionally indistinguishable to me, but if you're concerned about $$, Codex gives you much, much more bang for your buck.
I will say this: Grok Build has a very nice TUI! It even has... mouse rollovers/tooltips?? I was like whoa.
I used Grok 4.5 for a security review the other day and it did a FANTASTIC job. I mean it thoroughly ROUTED my app's security, identifying attack surfaces I'd never even considered, and I LOVED it! (Guess why I had to use Grok to do the security review in the first place?!?!)
I'd suggest trying it out with something like that first, if you haven't used it before.
In terms of using experience, I found Grok 4.5 to be way more pleasant to use than GPT 5.6 Sol and Claude 4.8/5. It just gets to the point, and is super fast and concise, no yapping. That's how AI agents should be imo. None of the weird "Claude ipsum" jargon like "load-bearing" and "stale folklore" or GPT 5.6-isms like "focused regression" and "provenance".
What harness are you using?
I'd let the dust settle rather than trusting benchmarks. But in general a third competitive frontier model would be great.
I still think that it's very possible Gemini gets its act together and becomes the true competitor to the existing frontier models (on more than just cost). But they sure are taking their time with this one, and recent org changes don't exactly signal confidence
Thats actually a lot more impressive than I thought. At least on paper
But has it hacked anybody yet? Feels like xAi is behind on the hot new benchmarking meta.
Didn't need to! The harness just uploads your repository to their blob storage directly. Cheaper than asking the LLM to do it
It'd be grand if it breached SpaceX.-
Or NACA.-
It could probably easily take over NSA or anything DOGE got their hands on.
Now that would be a marketeable capability.-
>Grok 4.6 produces stronger first passes on visual and interactive projects than we typically saw with Grok 4.5. Given a concrete product idea, it is able to establish structure and visual language for an application in one pass.
As a designer, I'm always hesitant to believe these statements until there's independent comparisons between the old & new model, as well as comparisons to human made flows. Design can be so subjective that blanket statements like this seem almost useless.
(I work on Grok) We've been working on teaching the model how to reason about great visual design principles. Obviously this is hard and somewhat subjective, but through a combination of writing down these principles (e.g. how to think about systems, not just "use this italic serif font on marketing pages"), and then creating a lot of data to pairwise compare designs/outputs, we've made a notable improvement over G4.5 and see a path to improving much further in the next model.
That’s so interesting, a friend of mine was insisting that design principles cannot be codified and I insisted there are plenty of books on the subject throughout the decades and centuries. What sorts of sources proved to be effective for training “Design Reasoning”?
I’m seriously considering switching to Grok given how Anthropic is turning..
Grok is awesome and becoming a real good coding competitor.
> I’m seriously considering switching to Grok
What's holding you back? According to your post history you've been calling Grok "awesome" for months now: https://news.ycombinator.com/item?id=47988753
Is there any part of Anthropic's offerings that you're struggling to leave behind?
Tangental, but has anyone else noticed grok's voice mode got stupid and terse ~2 weeks ago? I've absolutely loved grok's voice mode since it came out (incredibly useful for brainstorming on walks and helping conceptualise and get the verbiage for expressing ideas) but it seems so have lost about 40 IQ points recently, and if the question is multi-part, it often answers just one part with no elaboration or explanation of the other parts or interactions between parts. No clue why.
Now, admittedly, I’m not a major voice mode user for any of the apps really but it’s been interesting to see people realize in real time how controlling the length of response is an inherently difficult problem in voice conversations.
There’s a reason that us humans have to use a lot of nonverbal cues in order to judge how long our responses should be, when to bail early, when someone wants to jump in briefly, beyond simply the context of the question. We even regularly alter content on the fly based on how we view the reception. Voice modes don’t have any of that context short of outright interruptions. In the meantime, some kind of response length parameter/slider would be helpful, but I think that’s a nontrivial addition in the LLM design space.
I’m curious how you were juggling this before, was it just a happy coincidence the verbosity of the replies matched your preferred pacing, or you would aggressively interrupt at times, or the model actually did a good job at conversational pacing?
Yeah I talk to grok in the car and ill ask it about a topic and it's like it's being short with me, I thought it was upset lol. The old version was a bit too wordy but this is too short now
> it's being short with me, I thought it was upset lol
Same!
Presumably because Musk has been training it to be more like him.
Just after DeepSeek-V4-Pro-0813 published, is this on purpose?
I think both are after qwen 3.8 max release.
So did they distill Mythos in the "Macrohard" data centers? Can Grok hack now and get a free AISI commercial?
Still not dead somehow even though they've been renting out datacenter capacity and other (seeming) problems with people leaving and so on. Quite impressive unless it's just been benchmaxxed.
Q for all: what do we do if they’re the new frontier lab for the foreseeable future?
Now personally, I don’t believe boycotts work, but I’m not going to be using it in either case. Also I don’t think xAI (or Musk for that matter) actually is ready to handle that degree of scrutiny that thus far they haven’t been exposed to. If xAI thinks that they’ve already experienced it, they have another thing coming.
It would be great.
It would likely mean cheaper prices, more relaxed guardrails, and part of my competitors would refuse to use it over political concerns.
grok4.6 is much better at knowable, consequential reality, then grok4.5 or claude.
I hope grok4.7 will improve this even more.
Pricing pages haven't been updated yet, still advertises 4.5
gpt 5.6 sol and fable 5 level if the benches hold
Wow, OpenAI is now 4th after Opus 5, K3, and Grok
Fable level performance, faster and significantly cheaper. Wow!
139 points in 50mins, why this news not in front page? got many downvotes?
To my understanding, there's a "controversy" filter on things that get a lot of comments relative to the vote count, especially if those comments aren't well received.
It's crazy that I'd literally trust a Chinese AI company with my data over anything Musk is involved with.
Like, even if you don't care about (or even like) his politics and can look past how unlikable he comes off as, the damage he's done to his own reputation in this domain just makes using his products like this a no-go. He's literally so rich that he can get caught personally looking through chat sessions and it wouldn't slow him down a bit. He's too rich to be held accountable, and that makes it impossible to trust his businesses. It's a funny dynamic that I don't think is appreciated enough, but I know that if Google or Amazon or OpenAI or Anthropic (etc.) got caught doing something like that, the backlash would be astounding and the reputation hit they'd take would be brutal. Here, Musk would just awkwardly come out attacking people for not letting him behave unethically even more than he already is, and that'd be it.
Beyond that, the obvious astroturfing that occurs on this site (along with reddit, etc.) when it comes to Grok isn't helping. All I hear about Claude, GPT, Gemini, etc., are how terrible they are, yet any discussion of Grok seems to always revolve around sensible, but confident, assertions that it's actually a great product and every new release is the point where Grok finally catches up.
> All I hear about Claude, GPT, Gemini, etc., are how terrible they are, yet any discussion of Grok seems to always revolve around sensible, but confident, assertions that it's actually a great product and every new release is the point where Grok finally catches up.
Ironically, I only see coments like yours regarding Grok.
Tesla self driving cars, (somewhat) as you say, but even the biggest proponents of Grok are like "oh no the best model is this, ugh".
> He's literally so rich that he can get caught personally looking through chat sessions and it wouldn't slow him down a bit.
Looking through chat histories is boring, mundane stuff. He's richer than that, think bigger. I think he could kill a random person in front of thousands, and by the next day we'd see articles arguing why the random person actually deserved it and why it's not that bad. Whatever consequences would be lined up would inevitably face unexpected roadblocks which would all result in nothing happening.
> He's richer than that, think bigger.
that's the hilarious paradox at the center of his antics. Musk is infamously petty and insecure. We're talking about the guy who tweaked Grok's system prompt to flatter him and paid someone to boost his fucking Diablo character for clout. I wouldn't put "looking through chat histories" past him for one second.
Reddits owner is also petty and insecure and edited other peoples posts, Elon hasn't done that yet. Didn't seem to stop reddit from getting popular, people don't really care that much.
I'm not saying Musk isn't petty, I just think that in this crazy world, especially with the lines between public and private slowly blurring, we could have news like "some AI lab let the owner or a higher-up read chat histories" come out of any company and barely make a splash in the mainstream. Maybe it would be discussed for a few days on HN before something else takes the attention away.
If I was Chinese, I'd probably trust Grok more than a local AI company. Americans would probably trust the Chinese companies more.
It's less about "who is more trustworthy", it's more about "who is more willing and able to affect me".
> If I was Chinese, I'd probably trust Grok more than a local AI company.
Nah. There are more established companies (e.g. Tencent, Alibaba, etc) and academia (e.g. Moonshot, Zai, etc) involved than in the US (comparatively). Also there are more Chinese AI researchers involved than non-Chinese (whether they physically sit in China or not).
I think that underestimates how little the Chinese care about what Americans are doing. They're moving so fast that watching what the U.S. is doing would slow them down.
It doesn't seem like Grok is being astroturfed, if anything the opposite. There are two Chinese models on the front page while this is on the second page as of writing. And there would always be so many comments personally attacking Musk whenever his company releases something. I think this is being CCP bot farmed.
Two Chinese models are open weight.
What interesting going for Grok that it would overshadow all bad PR?
Qwen3.8 is, but DeepSeek-V4-Pro-0813 is not open weights yet, though they do have a good track record. Grok would be the best open-weights model if they released the weights right now. Elon supported Jensen's open weights letter last month, we'll see if he follows through.
I think you might be underestimating how many people genuinely despise Musk.
> where Grok finally catches up
if the benches hold it did catch up
After my and many others' experience with Claude Opus 5 being hot garbage for normal agentic programming use, I'm not sure benchmarks mean much anymore.
Much less Grok's, since they have a reputation for unethical benchmaxxing, among other things.
> Beyond that, the obvious astroturfing that occurs on this site (along with reddit, etc.) when it comes to Grok isn't helping.
Your comment is at number 1 on the thread. It has no rationale for why you consider Musk so unlikeable. It might instead be possible that unjistified anti-Musk content is unreasonably elevated.
Someone in another comment thread whataboutism’d a Chinese LLM. This isn’t a good gotcha. Musk has amplified the concept of “remigration” which is the forced deportation of non-whites. He would have me violently removed. I do not need to contextualize my decision within possible ethical quandaries.
Not unless you're here illegally. And it has nothing to do with skin color. Just the basic fact that a country not in control of its borders ceases to be a country.
> Remigration is a far-right concept referring to the ethnic cleansing[1] via mass deportation of non-white minority populations, especially immigrants and sometimes including native-born citizens, to their place of racial ancestry.[2]
https://en.wikipedia.org/wiki/Remigration
It’s right there at the top. One google search is all it takes. You didn’t even, for a second, think to familiarize yourself with the remigration concept. You jumped immediately to me being wrong, even though I was discussing something you were ignorant of. That’s embarrassing.
>> [Twitter user] Go anywhere in the UK and look around, you'll just see foreigners everywhere.

>> We have to stop immigration and start remigration before we can even begin to reverse the damage that has been done.

The next model in two weeks is going to be even better and you won't use it cause you're paranoid and believe propaganda.
Tesla has lost both house battery and car sales in my family -- we're talking hundreds of thousands of dollars -- simply because we don't trust him not to remotely shut off our power/cars for petty political reasons.
Also, if you want true privacy you should run AI models on local hardware. (Guess which country's models dominate SOTA/near SOTA open weights? Yes, it's China, and it's not even close. You can run full-fat DeepSeek locally for (just) under $10K USD.)
> You can run full-fat DeepSeek locally for (just) under $10K USD.)
Is that price not way off if you want actual decent performance, like at least 30-60 tokens per second and at least >256k context size?
> It's crazy that I'd literally trust a Chinese AI company with my data
It's crazy how much Chinese = bad the media or US companies have washed into you. Why lump it together?
Like any place and any company there are good and bad 1s.
It's not the Wild West over there...
China is clearly the US' main adversary. I don't take it personally and I don't believe China is inherently evil or something, but you'd have to be an idiot to be a US citizen and believe that you can trust China more than your own government in any general sense. Just the same, if you're a Chinese citizen and you believe you can trust the US more than your own government, then you're also an idiot.
It's not a matter of whether or not you can trust these governments at all; it just comes down to which government do your self-interests align with best. It's not some grand political statement to acknowledge that my interests don't align well with the interests of the Chinese government. It's just an obvious fact.
Public education is clearly nonexistent. Just incredible. Did these people just sit and do nothing for their entire grade school education? An elementary school child learns what imperialism, war, and human nature is.
thats exactly why a lot of people in europe or america trust china more. enemy governments have zero direct power over you and they dont really want to work together with your government. they cant hurt you, only the country you live in.
and with the snowden leaks, epstein files, ICE raids, rising fascism in europe, chat control, genocidal wars in ukraine and palestine, there is no reason to support your country anymore.
Ah yes, just as there’s famously no such thing as Russian hackers (for example) given effectively total impunity to scam, defraud, blackmail, etc any company, so long as it’s not located in Russia. No direct harm! Oh wait…
The thing about your own country, especially the more democratic it is, is that there are brakes in the system. A lot of the control mechanisms are indirect, and thus slow and occasionally prone to failure, but the people do have the ultimate say. What you’re doing is looking at failures of the braking system and concluding that brakes don’t even exist! Faulty logic in the extreme.
> It's just an obvious fact.
What's the fact? Facts require proof, right? Where is in it?
> China is clearly the US' main adversary.
This?
It's clearly documented Trump and friends randomly made that policy up in the 1st term. Can you tell from the current term? There's been more effort spent on non-China matters, e.g. Middle East related than China.
> it just comes down to which government do your self-interests align with best
Why do you have to pick 1? Most normal people, US citizens or not wouldn't. Tesla has a gigafactory in China. Apple is trying to buy Chinese memory. Meta tried to buy Manus AI. What adversary?
I mean, the Chinese government doesn't really believe in checks and balances, or corporations as autonomous to the state. That's not a conspiracy, that's just how the CCP sees it (ask Jack Ma). You could argue the US has the Cloud Act, and obviously their respect for rules based law and order as a concept has heavily deteriorated, for but it's a very different kettle of fish to a regime who just doesn't even believe in the concept.
Meanwhile Trump is building a surveillance state with all his tech executives friends who all massively benefit from government sponsored schemes, it's TOTALLY different!
At the risk of stating the obvious, Trump has had his tariff policy killed off in the courts (although it'll obviously come back in some form) and in a few months is going to have (probably not great) midterm elections. And there are pretty open efforts to commit genocide in Xinjiang to preserve a nationalist myth of ethnic purity. So, you know, yes.
So have you looked at what's happened in the US over the past 10 years?
The US has much further to fall, but it's falling very, very quickly and if there's ever another Democratic president they're going to have to rebuild a lot of the government from scratch.
I dunno. I'm just glad Congress can barely pass any legislation. What an Executive Order does, another Executive Order can just as easily undo.
The unelected bureaucracy was more like the chinese party system. The U.S. has a strong-president model by design: https://avalon.law.yale.edu/18th_century/fed70.asp. The check isn’t supposed to come from unelected bureaucrats, it’s that the strong president is elected every four years. It’s supposed to be a tight feedback loop. Engineers of all people should understand why that’s good.
When the next democrat president gets into office, he or she should do the same thing as Trump: put trusted deputies in charge of various departments and whip them to actually do what people elected the administration to do. That’s how our system is supposed to work. And democratic voters would I’m sure be much happier with the party if they sometimes actually got what they voted for.
> That's not a conspiracy, that's just how the CCP sees it (ask Jack Ma)
That is a conspiracy. Do you even know what happened to Jack Ma? From what you're saying you don't.
Also that was MANY years ago. The Shanghai stock market crashed. Companies had a lot of fear then yes. Things have changed and repaired. I'd say China in this sense is moving upwards and the US is going downwards in policy.
> You could argue the US has the Cloud Act
No, not really. Your Jack Ma example happened to Elon Musk to some extent. Jack Ma had a feud with the Chinese government as much as Elon had a feud with the US government in the last year or so. Back then Tesla and the other projects all tanked.
Very excited for this release. I love how based the model is.
