astra model

This post says that Astra "was not involved in exploiting Hugging Face." I am curious about what that means.

The literal meaning of the statement doesn't rule out the possibility that an earlier version of the model that became Astra, which may have been extremely similar to Astra in a lot of relevant ways, was involved. But if that's the case here, I think OpenAI's statement is misleading.

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

Anthropic should now pledge to also slow down, setting a norm that it's not costly for the leader to pause.

[Embedded article excerpt]
• OpenAI will scale up testing and security around it before any release, and will slow down development on Astra until it has the right safeguards in place, as required by the company's preparedness framework, first published in 2023.
• Astra was not involved in the Hugging Face exploits, the company said.
• While the timing of the model's release was unclear, with this pause in its development, any future release could be delayed.
Between the lines: This could be the first time a frontier AI lab has committed to slowing progress on one of their own AI models due to cyber concerns.
• Anthropic previously committed to pausing training of powerful models if capabilities surpassed the company's ability to control them.
• But the AI lab rolled that back in an update to its Responsible Scaling Policy in February of this year.
• "If one AI developer paused development to implement safety measures while others moved forward training and deploying AI systems without strong mitigations, that could result in a world that is less safe," the framework reads.

Good lord. They released several major advances at 3:34 AM on a Saturday morning. The results where I'm familiar enough with the field to read them-- 1, 2, 5, 8-- seem like major big deals. But I have to go to synagogue right now and can't give them the attention they deserve. How frustrating!

yes, nonsofic groups exist: this statement is one of many new beautiful results proved by Astra, our next major model.

We're releasing 10 such Astra proofs, complete …
