#14$10 per million input tokens and $50 per million output tokens sol is $4 / $20
2.5x more expensive than Sol.
Can expect 2.5x more usage in Codex subscription.
Sol is already brutal (even after their recent fixes, it's just a token-hungry model: I go through a full 20x account per day, on Sol Med/High standard speed, with ~2 threads). I hope the efficiency gains are true, since their token efficiency claims for Sol were bullshit.

#15I'm seeing reporting it gets 98.6% on ARC-AGI3[1] (previously like 30% with Fable) https://venturebeat.com/technology/welcome-to-the-agi-era-op...
The blog post says 99.9%. Oddly, it does better on ARC-AGI-3 than it does on version 1 or 2 of the same benchmark (though gets 95+ on all three)

Is the ARC-AGI-3 score with their custom harness? I'm guessing that is what the footnote is for? (per https://openai.com/index/how-two-settings-tripled-our-arc-ag...)

The annotation on arc-agi-3 is this:
> OpenAI's own evaluation notes say Astra uses the company's Responses API harness, while comparison models can operate under different configurations.
With this configuration gpt-5.6-sol was able to reach 38,3%. So this is misleading.

"On the current ARC-AGI-3 leaderboard, conventional frontier-model runs sit dramatically below Astra's reported 98.6% result.
But the comparison isn't straightforward.
OpenAI's own evaluation notes say Astra uses the company's Responses API harness, while comparison models can operate under different configurations."

100% on ExploitBench seems fitting given recent events.

I think we need a few writing related benchmarks.
