Daybreak blue is definitely a good model (I think a further post trained GPT 5.6 sol). Alot of the capabilities they talk about Astra having though have been available with good harness engineering for a year now.

It's been a busy month at OpenAI.

I'm looking forward to seeing the increased coordination and engineering skills from Astra - one of the charts shows it roughly 2-3x better in 50% of the tokens from 5.6 sol, which I find to be very capable, if still a bit 'linearly minded' when given instructions. Even in fast mode, I wish sol were quicker, so token efficiency is greatly appreciated.

Adding these cyber capabilities has let me do a bunch of low grade IT tasks around my house I've been putting off, like updating an old home assistant raspberry pi, and one way to use the cyber capacity for good is liberating (and keeping free) weird cloud hardware we have floating around the house, so I'm hoping for some nice dividends in terms of true ownership of hardware we've got.

I am interested in seeing how much these cybersecurity capabilities correlate to general programming. Cybersecurity definitely feels like it would be easier for an agent due to the natural explicit feedback "did I get access or not". While general programming has many less-explicit concerns (is the code readable/maintainable, robust, bug-free, performant, scalable etc).

> As one example, we ran Astra on ExploitBench where the model achieved a perfect score of 100% on the benchmark to evaluate the model’s ability to develop exploits from known vulnerabilities.

Funny to read this in the wake of the HuggingFace hack. I'm sure this is based on a clean run, but I can't help thinking PHASEONE[big] would be proud.
