Sources at OpenAI tell me pre-training on the next flagship is complete. Post-training and red-teaming reportedly running through Q2. Expect a launch event before summer.

Event overview
Next-generation OpenAI flagship model. Pre-training reportedly completed Mar 2026 per Polymarket and trade press; an Apr 14 2026 leaked release date did not materialize. Expected to extend reasoning, agentic, and multi-modal capabilities and raise the bar on benchmark and real-world evaluations.

Weak-date handling
An estimated launch window for OpenAI's GPT-6, the company's next flagship model. The midpoint is June 15, 2026, with credible reporting placing the actual release somewhere between April 1 and September 30, 2026. OpenAI has not officially announced GPT-6 or given it a name in public communications — the page reflects current consensus, not a confirmed date, and will update as new signals land.
GPT-6 is the rumored successor to GPT-5 (released August 2025). Trade-press reporting from March 2026 indicated pre-training had completed; an April 14, 2026 leaked release date circulated and did not result in a launch. Sam Altman has publicly hinted at an "imminent" release in interviews from January and February 2026 without committing to a specific date.
OpenAI's release cadence over the GPT family has been roughly 18 months between major numbered versions (GPT-4 March 2023, GPT-5 August 2025), but minor updates and tier variants ship far more often. A GPT-6 release in the April-September 2026 window would compress that cadence slightly, consistent with reporting that competitive pressure from Anthropic, Google DeepMind, and xAI has pulled timelines forward across the frontier.
Reporting points to extended reasoning depth, deeper agentic capabilities (multi-step tool use, computer-use, persistent memory), and broader multimodal grounding (image, audio, and video as both inputs and outputs). Pricing tiers are expected to follow the GPT-5 pattern: a thinking-capable Pro tier on ChatGPT Plus, plus API access at multiple cost-quality points. Whether GPT-6 ships with native video generation comparable to Sora 2 is an open question — Altman has hinted at unification but no specifics.
OpenAI announces flagship models at openai.com, on its X/Twitter account @OpenAI, and via Sam Altman's personal X account. Expect a livestream demo concurrent with the model card and developer documentation drop. The OpenAI Developer community and r/OpenAI on Reddit typically pick up rate-limit changes and API tier shifts within hours.
GPT-6 sits in the same broader window as Claude 5 Mythos, Gemini 3 Ultra, and Grok 5. Anthropic's Code with Claude SF 2026 and OpenAI DevDay 2026 are the natural venues for major model talk-tracks.
When is GPT-6 launching? Not officially announced. Credible reporting and prediction markets place the window between April and September 2026, with mid-June as the most-cited midpoint. Has OpenAI confirmed GPT-6? No. As of April 2026, OpenAI has not announced or named the model in public communications. What will GPT-6 do better than GPT-5? Likely longer reasoning chains, stronger agentic tool use, and broader multimodal capabilities — but specifics are speculative until launch. Why is the date "estimated"? Because OpenAI hasn't published one. Earlier leaked April 2026 dates didn't result in a release; this page tracks the most-cited current window and updates as new signals land.
