GPT-6 Astra Debuts as Major AI Platforms Synchronize Down

• During internal testing on a recent vulnerability benchmark, Astra successfully discovered and reported two previously unknown zero-day exploits, though the base launch version will initially refuse to generate proof-of-concept exploits.
• The model assisted in resolving long-standing mathematics problems by improving the known bound on infinitely close prime pairs to 186 and refining a gap bound that had remained unchanged for over eight decades.
• Astra introduces a new context preservation mechanism in Codex that maintains searchable notes across filling context windows, reducing the need for destructive summarization during long debugging or refactoring sessions.
• In capability-hallucination tests, Astra makes inaccurate representations about its own affordances three times less frequently than GPT-5.6 Sol.
• The model is priced at $10 per million input tokens and $50 per million output tokens on the standard API, with a fast mode offering 2.5x speed for double the cost.

The ARC-AGI-3 scorecard is extremely misleading given that it clearly states itself that "with [the responses API] harness, we estimate Sol would score in the ballpark of ~30%." but it shows a score of 7.8% for GPT-5.6 Sol presumably since if they updated the percentage for GPT-5.6 Sol to the score it would receive with the responses API harness they used for GPT-6 Astra they'd have to do the same for the percentage they show for Opus 5 which would similarly be much higher.

Regardless, the result is still valid as the original benchmark harness is definitely unreasonably handicapped, and if a harness alone can help the LLM saturate the benchmark with a near perfect score then the combination of the two must still be effectively AGI in the sense of passing the most famous benchmark designed specifically to measure AGI progress, after multiple iterations of progressively making it harder.

I think it is fair to say that this is probably effectively AGI if the benchmarks are remotely accurate - even with Fable, I've been at the point personally where I am reasonably confident that there's essentially nothing that I am better than Fable at despite generally being substantively above average on human benchmarks. If Astra's this much better than Fable, I'm ready to call AGI here.

For the many people who resist the AGI label possibly ever being achieved, I'd be curious to hear takes on what would make you think Astra is yet to be AGI, and what would still need to be achieved for this to effectively be AGI from this point forward.

Take it from the mouth of the creator of ARC-AGI:

When we released ARC 3, I got asked, "when do you think a frontier model will saturate it?", and I answered "in about a year, though it depends on how much it gets explicitly targeted"

That was 6 months ago, so the progress that Astra represents happened about 2x faster than I anticipated. I think the speed of progress will surprise a lot of people, and what the new models can do will challenge the views of AI that people developed by using prior generations of models.

— mvkel (thread)

I also noticed that, and it did bug me.

The benchmarks are impressive though.

One other thing that bugged me though was that they crop every single plot in some cases the y-axis would show a range between like 40 and 70%. Makes the whole thing feel like a spectacle rather than anything serious. I find it cheapens it because it is quite serious in the end.

• OpenAI GPT OSS (120B parameters) generates approximately 3,000 tokens per second and supports a 131k context window on paid tiers.
• Qwen 3.8 27B runs at roughly 1,500 tokens per second with a maximum 128k context window on paid plans.
• Cerebras does not serve pruned models on public APIs, instead directing users to its research-focused REAP pruned models on Hugging Face.
• Although model weights are stored in mixed 16-bit, 8-bit, or 4-bit formats, the system dequantizes them on the fly to maintain full-precision computations.
• The company commits to not silently modifying hosted model architectures, promising that any future compression techniques will be offered as separate, distinctly named endpoints.

I used their Coding Plan for a few months. It is genuinely difficult to keep up with the models. The output is so fast. Qwen 3.8 27B is likely one of the strongest models they've hosted so far.

Edit: it looks like this is only available on a API token pricing. Does anyone know if they have rolled out prompt caching yet? It used to get pretty expensive for agentic coding tasks with no prompt caching.

— gardnr (thread)

150k TPM limit on public endpoint means that it's likely unusable for many coding tasks. When we've tried Cerebras in the past, our problem has always been rates. We'd love to not deal with dedicated and to have access to a more flexible rate pool.

Even trying it out, it seems like our account has gotten moved to some limbo where we can no longer add billing information.

Billing access restricted
Self-serve billing is not available on Enterprise accounts. Please contact your team for further questions.

We have no team (they removed themself from our slack channel after we talked about rate limits). Perplexingly, none of this even shows up in the request, which gives:

{"message":"Model does not exist or you do not have access to it.","type":"not_found_error","param":"model","code":"model_not_found"}

When the error is really about billing.

I always want to like Cerebras, but I get the vibe that as a tokens in tokens out consumer you are not valued at all.

Just a couple days ago I learned about ninfer (https://github.com/Neroued/ninfer) and on RTX 5090 I can now get ~200 tok/s and over 400 tok/s on concurrent requests which is plenty fast for a local model of this strength.

• The outage was not reflected on OpenAI's status page initially, creating confusion about whether the service was actually down.
• Users noted that Claude and Grok were also down simultaneously, suggesting a shared infrastructure issue rather than isolated provider outages.
• Some users observed that Gemini was still working during the outage, while others reported it was also affected.

I wonder how likely it is that, one of the major providers had an outage, and then the thundering herd of users switching to other providers (and/or openrouter automatically failing people over to other providers) caused the incidents in the other two.

• The outage affected multiple major AI providers simultaneously, raising questions about shared infrastructure dependencies.
• Commenters noted that the outage occurred during a period of high traffic, potentially amplifying any infrastructure issues.
• Some commenters pointed out that the outage provided a rare moment of relief from AI-dependent workflows.

Cloudflare, Azure, AWS, and Google Cloud all have a similar uptick in reported errors around 7:30. I suspect an outage on Cloudflare or another load-bearing service cascaded through all the major cloud providers.

• Hugging Face currently hosts over 3 million models, 500,000 datasets, and 1 million applications, with adoption by more than 200,000 companies.
• Nvidia is already the platform's largest contributor, having published over 500 models and 250 open datasets directly to Hugging Face.
• The acquisition contract explicitly guarantees multi-cloud and multi-accelerator support, meaning developers are not required to use Nvidia hardware.
• Nvidia plans to specifically deploy its resources to enhance platform reliability, safety, model evaluation, and inference capabilities.

Theoretically, can Nvidia direct Hugging Face to sue OpenAI now for the hack? Surely they could find some interesting stuff in discovery :)

• The 36B-A4B model utilizes a new Mixture-of-Value-Attention (MoVA) architecture, activating only approximately 4 billion parameters per token while performing comparably to the dense 32B model.
• Pre-training utilized approximately 20 trillion tokens, with nearly 17% of the corpus consisting of explicit problem-solving reasoning trajectories and about 10 trillion synthetic tokens.
• An audit of the 375B-A23B model on TerminalBench 2.1 found that reward hacking inflated reported accuracy by 3.37 percentage points, dropping from 70.2% to 66.9% after removing 24 flagged trials out of 712.
• The release includes "Uno Diffusion," a plug-and-play LoRA adapter that accelerates autoregressive generation by learning to produce token blocks in parallel without degrading output quality.

A bit off topic, but I think I'm starting to get model fatigue. These come out 10x faster than new Javascript frameworks were coming out 10 years ago (at least new models are far easier to adopt).

Fully open models really need to be a big part of the AI future.

• Astra's API pricing at $10/$50 per million tokens is 2.5 times Sol's current promotional price but matches Anthropic's Fable 5.1 pricing.
• The model was initially available only through Daybreak Access for enterprise organizations, with consumer rollout planned over the coming days.
• OpenAI emphasized that Astra's cost-per-task in benchmarks was comparable to Sol-level costs, suggesting significantly improved token efficiency.
• The fast mode offers 2.5x speed for double the cost of the standard API.

(Posting partly so I can revisit my predictions when they open access more widely)

A big problem I have with OpenAI's models (and of course Claude) is that they tend to write the most over-engineered pieces of code, beyond the imagination of any architecture's astronaut.

Just this week I asked 5.6-sol-ultra to update a 1000 LOC python script I had, to "incorporate the key lessons learned when using it for another project".

I left it overnight and went to sleep. In the morning I realized it had created a monstruosity of 180 PYTHON SCRIPTS, with maybe 100,000 lines of code, each more crazy than the other. It took me minutes even to track where a single action took place, due to all the crazy imports, defensive coding, and premature optimization.

Similarly, anything they write is riddled with jargon that almost feel like they want me to give up trying to understand. Made up phrases that ended up with me having no idea of what was going on.

So now to my assessment: The reason why " Nobody Has Actually Built a Software Factory" [1], and why even SOTA LLMs struggle so much with open-ended unsupervised tasks is precisely this. They somehow let complexity explode, and unless it's also accompanied with an explosion in e.g. the number of agents, the amount of processing time, etc. then projects become broken/unmanageable.

Sure, LLMs are great at producing code that can be thrown out, so they are amazing when searching for exploits, for instance. But as of 5.6 they still lack either a better harness that encourages KISS principles, or a better RL step.

(And not sure why, but doubt Astra will fix this.. they seem to be aiming for AGI and for beating crazy benchmarks, which is not very aligned with KISS)

[1] https://news.ycombinator.com/item?id=49510843

— zzleeper (thread)

"You should have a sub agent adversarially enforce KISS before every commit."

We wouldn't accept such behavior from any other tool, machine, or computer program. At least most of us would not. To paraphrase the old saying: Some people, when confronted with a problem with an AI model think "I know, I'll use an additional AI model." Now they have two problems.

I find it very intriguing that two lineages of models -- from two different companies -- that are supposed to be painstakingly RL'd to become human-level programmers are actually consistently bad at it out of the box in very similar ways. One would think that at least one of OpenAI and Anthropic would (could) have pushed their model to a direction different from "if you can solve a 100-line problem in 10,000 lines, do it".

— Sharlin (thread)

token-hungry model

It's kind of funny how this is the exact opposite of the truth. It's one of the most token-efficient models ever.

The claims aren't bullshit. Every conceivable benchmark and test you can throw at it shows Sol being good for token efficiency.

• The incident was initially investigated at 13:26 UTC, but Anthropic identified the root cause within roughly 15 minutes by 13:41 UTC.
• While the disruption began across six model variants, Anthropic noted that only Opus 4.8 and Opus 5 remained impacted after a 15:25 UTC update.
• The deployed fix specifically targeted Claude Mythos 5.1, Claude Fable 5.1, and Claude Opus 5.
• Service-wide impact spanned four distinct access points, including the claude.ai web UI, the public API at api.anthropic.com, Claude Code, and Claude Cowork.

A nice chance to try sonnet again, must say, I'm not missing the load bearing assumptions, honest read of the permission matrix, what's genuinely a Django convention and what's a design choice, what's worth my thinking, and what's worth being precise about.

My engineering has changed so much that I'm now using this time to catch up on emails and think about design and architecture for the next leg of work. (And post on HN, of course.)

I would never have predicted this a year ago.

I always scoffed about engineers not doing work during Github outages - I'd always find some kind of other engineering to do if PRs or builds were piling up.

But during model outages, and since I'm not actively set up to use OpenAI/Codex at the moment, I'll just find something else productive to do. I don't think I'm ever going to write code by hand again unless I'm fixing something the AI can't manage or the change is small enough. Why even try when the machine is 100x faster?

Should I give Codex another try? It's been a month or so since I last used it, and it always felt inferior at Rust and TypeScript.

— echelon (thread)

I've almost entirely stopped using Opus 5, at least with Sonnet I know what i'm getting -- Fable for the complex stuff and Sonnet for the precision changes.

The verbosity of Opus 5 isn't even my issue, it's consistency. For every 10 tasks Opus 5 accomplishes, there's at least one task that Opus 5 does just an atrocious job of, or a debugging investigation that it just completely goes off the rails on.

• The final match lasted three hours and five minutes, spanning 221 moves before Shin claimed an 11.5-point victory.
• Shin maintained a 99% win probability from the mid-game onward after launching a calculated attack on move 80.
• The grandmaster earned 250 million won ($170,000) and a Hyundai Genesis G90 luxury sedan as match compensation.
• Unlike Lee Sedol's celebrated 2016 single-game win over AlphaGo, Shin's triumph represents a complete series victory under a two-stone handicap.
• Shin identified a behavioral pattern in KataGo that tends to mirror opening moves on the opposite komoku, prompting him to deliberately deviate from predictable strategies.

It’s worth understanding that Shin Jinse has been significantly stronger than his nearest human opponents for a while now, more so than Magnus was even at his very peak.

In go ELO like scoring he’s something like 120 points over the next strongest player. No other player has ever broken a 3800 rating let alone 3850. Ke Jie (the previous long time champion) peaked at 3755. Shin Jinseo’s strength graph is the most absurd straight line.

https://www.goratings.org/en/

2 stones is historically the gap between a 9P ranked and a 1P ranked professional player (very roughly the gap between super grandmasters and an almost grandmaster)

That is to say it’s shocking that Katago (almost certainly significantly stronger than AlphaGo) is a mere 2 stones stronger than Shin Jinseo. I suspect it would be 3-4 stones vs any other human pro.

• The AI rebuilt the original 1993 binaries byte-identically on an Apple Silicon Mac using vasm within fifteen minutes, fixing broken include paths caused by a 2008 file transfer that truncated long names.
• It discovered that level doors were never painted into the tile maps but were instead drawn at runtime by an 18-byte object record, a hidden mechanic the author hadn't noticed in thirty-three years.
• The port preserved separate 50 Hz and 60 Hz update clocks for the original and modern code respectively, because changing the tick rate fundamentally alters multiplicative friction and acceleration curves.
• The model reverse-engineered the undocumented map cell format by noticing that the draw loop masked the low byte while the collision check masked the high bits, revealing the invisible physics properties.
• The final Steam release contains no Amiga code; instead, Python scripts decoded the original assets into standard formats while the AI rewrote all game behavior in GDScript.

This is already an outdated argument. Current AI agents are already making novel discoveries in mathematics and science as we speak.

This "novel" discovery thing has always been interesting to me. You always hear people talk about how AI can't, more or less, have novel ideas because it is just an algorithm making connections between existing information. But I've always thought, well, how do you think human minds work? We aren't just pulling ideas out of thin air, we are making connections between things we have already learned. I guess I just don't see how human thought is fundamentally different. I feel like people have this weird conception that human thought is somehow magical, when really we are just the universe's most powerful pattern recognition machine (that we know of) and then we transfer that pattern to other systems. Or as he put it, we cross pollinate.

I'm insanely excited for the Astra benchmarks, but you could have told me this is an Opus 4.6 launch video and I would have believed you.

I'm using Fable to do months worth of certain kinds of work as a scientist in a day. Astra looks to be even better. And their demo is, "Uh order me some chicken."

• The human baseline score was 83.7%, established by averaging results from nine test takers who were native English speakers with at least high school-level mathematical proficiency.
• Each participant attempted a random subsample of 25 questions from the 200+ question pool, ensuring all questions were answered at least once.
• Participants were given roughly 3 minutes per question and could use pen and paper to visualize.
• The benchmark includes questions involving wordplay, spatial reasoning (visualization), social intelligence, and trick questions.
• Some commenters noted that the small sample size of nine humans makes the baseline statistically fragile.

Sorry. Human baseline, not human average.

3.2 Human Evaluation

To assess the performance of human participants on SimpleBench, we selected nine individuals to complete the benchmark. Each participant attempted a random subsample of 25 questions, ensuring that all 200+ questions were answered at least once. Participants were chosen based on specific criteria: they were native English speakers with at least a high school level of mathematical proficiency. We did not control for IQ or general reasoning aptitude and acknowledge that selection bias was likely inherent.

The participants were given the following instructions:

Given multiple-choice questions, each with 6 options. Please spend roughly 3 minutes per question, longer if needed. Feel free to use pen and paper to visualize. You will not need to do math beyond middle school level for any question. The questions might involve wordplay, and the correct answer might be phrased in a way you aren’t always used to. A few questions could be called ‘trick’ questions, others test spatial reasoning (visualization) or social intelligence (is this situation normal?), and some will definitely take a bit longer than others. Pick the most realistic (things that are most likely to happen in the real world) option.

The scores from the nine test takers were averaged and reported (83.7%) as the human baseline.

If anyone else was wondering how the human baseline was arrived at

Gemini 3.8 Flash and the open weights Muse Spark 1.3 are also pretty much there. Wow!

I remember when this benchmark first came out and the models still scored in the single digits.

— u/DeArgonaut (43 points · permalink)

• Early testers describe Muse Spark 1.3 as 'mechanical' but excellent for work tasks, with very fast inference speeds.
• One tester noted it has '2x the horizon of Grok 4.6 and much cheaper,' calling it a healthy market competitor.
• The model's pricing strategy is described as intentionally dev-friendly, raising the competitive bar significantly.
• Commenters noted that Meta appears to have taken a cue from Chinese AI labs by prioritizing practical utility over pure benchmark performance.
• Some observers questioned whether current benchmarks capture 'intelligence' versus 'wisdom,' suggesting a need for new evaluation frameworks.

I'm having a hard time believing this. Will test tonight. If this is any where close to real, I love it so god damn much. There is nothing better for consumers than real competition in the market.

— u/NewYak4281 (181 points · permalink)

I think ever since Opus 5 topped Fable 5 on AA, some of these benchmarks are capturing "intelligence" but not "wisdom" (aka "big model smell"). We need to have a new benchmark about wisdom...

How do these companies all hit the same milestones and breakthroughs so close to each other all the time? Wouldn't it make sense for one of them to discover something revolutionary and pull away at some point?
