OpenAI DevDay 2026

San Francisco

On September 29, we're bringing developers together in San Francisco to go deep in technical sessions, test what’s new, swap notes, and bring their best questions and ideas to the teams creating OpenAI’s tools.

Applications to attend OpenAI DevDay in-person are now closed. Application statuses will be sent by late July. If invited, you will have 14 days to register before your spot is offered to someone on the waitlist. Registration is $650.

The opening keynote will be livestreamed. Sign up below and we’ll send you a reminder before it starts.
