To a vapid any goalpost moving on such a critical issue as AGI.

Can we all agree in advance what kind of Pelican would convince us it’s actually AGI.

For me it’s refusing to make a pelican.

Between the higher capability level and the change in reasoning tokens (supposedly using "neuralese"[0], which makes the monitoring more difficult), it seems we've entered a new frontier.

I wonder if this is going to be one of those days where you'll be like: Oh yeah I remember where I was when the first version of AGI launched

Probably not. It's probably just gonna do tickets better and that'll be about it.

Fair point - hopefully you're wrong though ;)

ARC AGI-3 saturated by Astra! https://arcprize.org/leaderboard

I think it could indicate that "semi-private" dataset likely leaked to their training data.

It says "Provider Adapter" so presumably they put some manual work in to make this work.

Hmm, 61 on ArtificialAnalysis, effectively matching GPT-5.6 and trailing the new Meta model. How is that possible along with the other metrics they shared? Insanely jagged intelligence?

Idk, this means the benchmark has bigger problems ... no way Astra will be worse than Opus 5

Only thing I would trust is the what X/Twitter crowds are saying about a model after 2-3 weeks of its launch. But before that I would already tried the model and have my own conclusion.

I really wish it was called chain of instruction. Because it's definitely not thought.

Just two days ago, a preprint by Julia Stadlmann went up on arXiv [0] improving the prime gap from 246 to 240. Now OpenAI announces Astra has shown a gap of 186 [1]. That must really blow. [0] https://arxiv.org/abs/2608.31126 [1] https://cdn.openai.com/pdf/51126fac-1b68-4128-9666-c908bcc16...

Such a result should be considered worthless: the proof is 10MB of Lean. ( https://github.com/openai/PrimeGaps186 ). I can't think of a single mathematical proof being anywhere close to ten million characters. For all you know, 90% of the proof could be useless, 8% would be writing out Shakespeare, and 1% abusing another bug in Lean. Humanity gets zero value from that, aside from "some bot seems to think it's 186". U…

You talk about modern math and worthlessness at the same time? That’s brave.

GPT 6 Astra benchmarks https://cdn.thenewstack.io/media/2026/09/358eb84a-screenshot... Performance is significantly higher than Fable 5.1 Source: https://thenewstack.io/openai-gpt6-astra-benchmarks/

> Performance is significantly higher than Fable 5.1

That's not clear. Need to see independent benchmarks first.

$10 per million input tokens and $50 per million output tokens sol is $4 / $20

It seems to use less than half the tokens for the same task compared to sol, and in some benchmarks closer to 2/3 less tokens. So the actual cost may be roughly the same or cheaper overall.

You’re not seriously suggesting that the model is secretly sandbagging its performance on GDPval and long context reasoning, while making huge and obvious progress on ExploitBench, ARC and science benchmarks, in order to tank its AA composite score, so it can conceal its true power level?

Why would benchmarks be an adversarial setting anyway?

Could it be possible that OpenAI may have had some other motive for saying their model “strategically underperforms”, other than just an innocent reporting of a truth it happened to discover?
