OpenAI DevDay 2026 is OpenAI's annual developer conference, scheduled for September 29 at Fort Mason in San Francisco. The single-day event gathers developers building on OpenAI's APIs and models for technical sessions, hands-on demos, workshops, and direct time with the teams behind OpenAI's developer tools. Content typically spans the latest model releases, the API platform, agent-building frameworks, tooling for evaluation and fine-tuning, and guidance on deploying applications at scale. In-person attendance is by application and invitation, with a registration fee of $650; applications for the 2026 edition closed ahead of the event, and OpenAI notified applicants of their status in late July. The opening keynote is livestreamed to the public at no cost, and other sessions are recorded and posted to OpenAI's site shortly after. Alongside the San Francisco flagship, OpenAI is running DevDay Exchanges in additional cities later in the year, including Bengaluru, Tokyo, Seoul, Paris, Berlin, London, Sao Paulo, and Mexico City. Primary audiences include software engineers, AI application builders, startup founders, and product teams integrating large language models. The Fort Mason venue continues DevDay's shift toward a larger in-person developer gathering.
