OpenAI slows Astra development after internal evaluations cross a cybersecurity threshold
OpenAI said it slowed development of its in-progress Astra model after internal evaluations found the system had reached the company’s "critical cybersecurity threshold." The Register also reports that OpenAI pledged to add further security measures around Astra, while Anthropic was described as easing restrictions on its Fable system in a contrasting safety posture.
Why it matters: A major AI lab publicly acknowledging that a frontier model crossed an internal cyber-risk threshold is a significant safety signal. The added detail that OpenAI plans further safeguards around Astra, alongside reports of Anthropic loosening controls on a comparable system, sharpens the debate over how leading labs should gate dangerous capabilities and communicate those decisions.
