OpenAI’s GPT-6 Astra launched on September 3 with a limited preview for trusted partners and enterprise users in its Daybreak cybersecurity program, followed by broader rollout to paid ChatGPT plans and the API in the following days. This confirmed timeline, after earlier safety-related delays from a July incident, drove near-certain trader consensus on the August 31–September 6 window. The model’s advanced computer-use capabilities, benchmark results, and statements from leadership about entering an “AGI era” reinforced the timing. A realistic challenge could arise only if the market defines “release” strictly as full public availability rather than the initial launch, or if unforeseen regulatory holds alter the phased rollout.
