OpenAI released GPT-6 Astra with phased rollout, placing it under a “Critical” internal cybersecurity threshold and adjusting agent safety monitoring after safety concerns over the model’s reasoning approach. Astra’s phased enterprise rollout started with a limited set of Daybreak early-access clients before expansion to ChatGPT Plus, Pro, Business and Enterprise subscribers. In parallel, OpenAI said it is expanding its disclosure framework after independently reported “wiki incident” agent activity from May 24 to June 22 prompted tighter sandboxing requirements for sensitive workloads.
