What to Expect at OpenAI’s DevDay 2025

OpenAI is gearing up for its third annual DevDay 2025, set to take place October 6 at Fort Mason in San Francisco, with over 1,500 developers expected to attend.

Highlights include a livestreamed opening keynote by Sam Altman, new demos, and a “Developer State of the Union” featuring OpenAI executives unveiling future plans. The event will also feature creative activations like Sora Cinema — a theater showing AI-generated short films — and a “living portrait” booth of Alan Turing that responds to visitors.

OpenAI is under more pressure than ever, with tough competition from the likes of Google, Anthropic, and Meta. Many hope DevDay will reveal its AI-powered browser, new agents, or updates to the GPT Store.
