OpenAI DevDay Exchange London

OpenAI's DevDay Exchange comes to London on 3 November, starting at 14:00. It is the regional follow-on to DevDay — a working session for developers already building on the platform rather than a launch keynote broadcast. Attendance is by application and the organisers review each one; the exact venue is shared with applicants after approval, so the address is not public. Applications were still open and under review when we checked. Why go: the Exchange format puts OpenAI's own engineers in a room with the people shipping against their API, and the London stop is the only UK date. Worth the application if you are building production features on OpenAI models and want answers from the people who maintain them. Best for engineers and technical founders already past the prototype stage.
