GPT-6
OpenAI has not announced GPT-6 — no date, no specs, no name confirmation. The model many expected to be it shipped as GPT-5.5 in April, and GPT-5.6 (Sol · Terra · Luna) followed on July 9 — by OpenAI’s own numbering, neither counts. What’s on record: Altman says the next generation arrives faster than the GPT-4→5 gap and that memory is the centerpiece. The market’s dated odds are in the ladder above, live — and the second GPT-6 answers on the public API, ArtificialWatch fires.

New leak: August target, 1.5M+ context, a new pre-train foundation
A fresh leak — circulating under both “GPT-5.7” and “GPT-6” labels, which itself tells you how firm it is — points at an August release: a 1.5M+ token context window, an entirely new pre-training foundation beyond the old base (with 10T-scale rumors attached), and substantial agentic/reasoning gains aimed at the Mythos/Fable tier. Nothing from OpenAI itself; if it ships as 5.7, the GPT-6 market doesn’t resolve. via WinCentral · Times of AI
GPT-5.6 goes public — and it is not GPT-6
OpenAI shipped its “most capable system yet” in three tiers — Sol, Terra, Luna — as a 5.x point release. The numbering now means the digit marks the generation and the tier names persist across it, so the next numbered drop is the one this page watches. Polymarket’s rules agree: 5.x releases don’t resolve the GPT-6 market. via OpenAI · CNBC
Altman’s “extra goblins” GPT-6 post — a joke, read as a hint
Altman posted a joke prompt reading “start training GPT-6, you can have the whole cluster. extra goblins.” Widely read as a playful nod that GPT-6 is next — not an official signal, and we don’t treat it as one. via Futurism · TechRadar
GPT-5.5 ships — the model many expected to be GPT-6
Instead of a numbered bump, OpenAI released the model reportedly codenamed “Spud” as GPT-5.5 — and it absorbed much of the memory and agentic direction previously teased for GPT-6, resetting expectations for the numbered successor to H2 2026. via lifearchitect.ai (reported) · FinancialContent
Altman’s clearest GPT-6 framing: memory first, coming faster
On the record with CNBC: GPT-6 will arrive faster than the gap between GPT-4 and GPT-5, and personalization is the point — “People want memory.” Still the most concrete official statement about the model. via CNBC
The official word.
"People want memory."
