Rumor update: GPT-6 said to slip to September — with a 'GPT-5.7' filling the August gap
None of this is confirmed by OpenAI. The rumor mill has shifted since last week's 'GPT-6 in August' wave: leakers now claim GPT-6 has been pushed to September and that OpenAI will instead ship an upgraded GPT-5.7 in August. Prediction-market traders on Polymarket and Myriad put roughly 77% odds on a September GPT-6 arrival. Meanwhile the eye-catching numbers from the earlier rumor — 10 trillion parameters, a 1.5-million-token context window — are now disputed even within the leaker community.
Why it mattersIf you tracked last week's rumor, this is the correction cycle in action: the launch window is drifting and the wildest specs are falling away, which is exactly how overheated leaks usually deflate. The steady part of the signal is that OpenAI is preparing a major release for early autumn — worth watching, not worth betting on.
