OpenAI began rolling out GPT-6 Astra on Thursday, making its latest AI model available first to participants in Daybreak, its application-based cybersecurity program, before expanding access to paid consumer and enterprise accounts in the coming days.
Astra is the first model OpenAI has designated "Critical" under its Preparedness Framework. This classification reflects the company's finding that the model can autonomously discover previously unknown security weaknesses and build functional exploits against well-defended systems, without a human directing every step. OpenAI said it delayed parts of the model's development over the past several weeks to strengthen and test protections against cyber misuse before proceeding with the rollout.
