OpenAI’s September 2026 launch of GPT-6 Astra, followed quickly by GPT-6 Sol, Luna, and GPT-6.1 Sol variants, has anchored trader views on the GPT-7 timeline. The roughly 13-month gap from GPT-5 aligns with OpenAI’s accelerating cadence and Microsoft-backed compute expansion at Stargate, pointing to a second-half 2027 flagship release as the consensus path. No official GPT-7 details or pretraining leaks have emerged, and the company continues iterating within the GPT-6 family while competitors release their own frontier models. Key swing factors for traders include any signals on the next major training run, regulatory or safety reviews that could shift timelines, and whether point releases extend the current series further into 2027.
