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.

txrx0000•about 1 hour ago
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?

Philpax•about 1 hour ago
I think you might be underestimating how many people genuinely despise Musk.
bryanlarsen•about 2 hours ago
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).

bmitc•20 minutes ago
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.

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.

calldacopsidgaf•about 1 hour ago
> 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.

tavavex•about 1 hour ago
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.

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.

itsdesmond•about 3 hours ago
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.
KerrAvon•about 2 hours ago
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.)

It's crazy how much Chinese = bad the media or US companies have washed into you. Why lump it together?

nater5000•about 1 hour ago
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.

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?

crimsoneer•about 3 hours ago
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.

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.

But professionals aren't asking AI tools about gender politics. They're using them to code and build businesses. I don't care if I'm using a model that has some crazy political takes that I don't agree with as long as it is good at the job it is doing.

nater5000•about 1 hour ago
This is a matter of politics; it's a matter of reputation.

I'm fine with using AI tools offered by companies like OpenAI, Anthropic, and Google despite knowing that these companies are ran by billionaires who are much more aligned, politically, to Musk than they are with me.

What I'm not fine with is handing over valuable data to a guy that has literally completely captured the US government and has shown a disdain for being perceived as someone who even pretends to follow social norms or respect societal rules. You can just look at his actions with regard to Twitter and you can see, without needing any political lense, that he's openly haphazard about this kind of technology and how he wants to use it, especially for his own personal gain, because he knows he's untouchable.

The guy just sucks at the job of being the face of these companies, and this is how sucking at that job affects the bottom-line. But, again, that doesn't matter to him because he has so much money that he can just personally bankroll past those inadequacies.

Looks like the SpaceXAI api is adding a default system prompt to all requests. 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

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.

And here:

I think polarizing is a generous way of describing the problems. My organization has outright banned Grok, because we don't trust SpaceX to hold up to contractual agreements vis-a-vis data-privacy/training. That's the level of reputational damage we're talking about here; and we use Chinese models (*hosted by US providers) for context.

causal•about 3 hours ago
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.

logancbrown•about 3 hours ago
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.
sm0ss117•about 3 hours ago
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.
causal•about 3 hours ago
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.

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?
legucy•about 1 hour ago
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.

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.
ayewo•about 3 hours ago
> 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

causal•about 3 hours ago
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.

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.

lanthissa•about 2 hours ago
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.

Jcampuzano2•about 3 hours ago
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.

this is exactly whats happening. Its funny having lived through this with snap dragons and phones.

enraged_camel•about 3 hours ago
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.

causal•about 3 hours ago
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.

What are suspicious of? If the timing is similar maybe just everyone already are of similar capabilities and got there at a similar time?

It means Anthropic had no real moat and no real lead. Is that weird to you?

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.

jorl17•about 3 hours ago
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.

cjalmeida•about 2 hours ago
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.

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".

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

Didn't need to! The harness just uploads your repository to their blob storage directly. Cheaper than asking the LLM to do it

>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.

leerob•about 3 hours ago
(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.
reilly3000•about 2 hours ago
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”?

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.

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.

You may not like Elon, but you must respect him. I don't think anyone expected 6 months ago that Grok would be at the frontier and beating openAI and anthropic. Competition is good.

The last time grok made these statement, I tried using it for my workflows and it did not perform as good as opus or even sonnet.

My guess is that xai benchmaxxes a lot but fails in actual capacity to produce good models.

j_maffe•about 3 hours ago
Why? Did Elon design Grok?
ihumanable•about 2 hours ago
Based on the discourse around Musk it seems like some people believe he's having some huge amount of input on

- Rocket Design

- Battery Chemistry

- Frontier level AI research

There's no way he's just a guy with a bunch of money paying smart people to do things.

qingcharles•33 minutes ago
At least Gates was honest that he "surrounded himself with smart people", and he has some really decent assembler code in his early years.
VariousPrograms•about 3 hours ago
There was that time Grok persistently brought up "white genocide" regardless of prompt, so I'd say Elon has a big personal role designing Grok's outputs!

dancemethis•about 3 hours ago
No, we mustn't. This improvement is in 1) merit of Cursor's team and ground-level "X-Ai" AI engineers and 2) despite Elon's meddling.

Just imagine how much he's trying to push internally that this new generation of Grok should be spouting his kind of propaganda.

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.
