OpenAI has not announced, previewed, or released any model named GPT-7 as of late September 2026. The current flagship remains GPT-6 Astra, launched September 3 to select partners and expanded shortly after, followed by cost-optimized GPT-6 Sol and Luna variants on September 22. Historical release gaps have shortened recently—from roughly 29 months between GPT-4 and GPT-5 to about 13 months for GPT-6—yet OpenAI has provided no official timeline or internal name for a successor. Trader consensus on prediction markets reflects this uncertainty, with implied medians clustering around late 2027 and low probabilities for anything before mid-year, driven by the absence of leaks, benchmarks, or executive comments distinguishing confirmed progress from speculation. Key near-term catalysts include further GPT-6 rollout metrics and any hints at the next major training run.
