On 2026-08-07 OpenAI announced Astra is its first "critical" cybersecurity model under the Preparedness Framework, citing preliminary evaluations, committing "additional controls," and stating an effort to make Astra’s advanced cyber capabilities broadly available to defenders via a linked blog post.

Why it matters

@Hesamation asserts "so Astra is basically OpenAI’s Mythos," equating Astra to OpenAI's earlier Mythos program.

Key details

  • On 2026-08-07 OpenAI said it evaluated Astra and is treating it as its first "critical" model for cybersecurity under the Preparedness Framework, adding "additional controls" and aiming to make Astra's advanced cyber capabilities broadly available to defenders (blog: "Responding to the next frontier of critical cyber capabilities").

so Astra is basically OpenAI’s Mythos.

OpenAI (@OpenAI)

After evaluating one of our upcoming models, Astra, we're treating it as our first "critical" model for cybersecurity under our Preparedness Framework.

This is a scenario we've planned for, and we're putting additional controls in place to ensure Astra's further development happens safely and securely.

We're working hard to make Astra broadly available, and get its advanced cyber capabilities into the hands of defenders.
