OpenAI pauses Astra model over critical cyber capabilities

OpenAI paused 'internal activities' on Astra after evaluations showed 'significant advancements in agentic coding and cybersecurity,' concluding it 'cannot rule out critical cyber capabilities' under its Preparedness Framework. The model was 'not involved' in the recent Hugging Face breach; OpenAI added 'universal monitoring' for risky actions across agentic applications.
