OpenAI’s recent GPT-6 family releases, headlined by GPT-6 Astra on September 3, 2026, followed by GPT-6 Sol, Luna, and GPT-6.1 Sol variants through late September, anchor current trader sentiment on GPT-7 timelines. These models deliver frontier gains in coding, computer use, and agentic tasks while expanding access via ChatGPT and the API, with ongoing deprecations of GPT-4 and GPT-5 series models signaling a focus on iteration rather than an immediate next-generation leap. Historical cadence points to whole-number releases every 13–29 months, and no official GPT-7 announcements, training disclosures, or previews have surfaced despite Stargate-scale compute investments. Key near-term catalysts include further GPT-6 safety and UI updates plus any developer conference reveals that could accelerate or delay the next major model.
