OpenAI says it has more than 20 announcements lined up, but hasn’t said what they are.

A 12-second teaser says OpenAI plans more than 20 launches in one day at DevDay on September 29. The clip names no products, so it’s too soon to tell whether that means new models, developer tools or smaller updates.

Sam Altman’s opening keynote starts at 10 a.m. Pacific time in San Francisco and will be livestreamed free. OpenAI says the event will include API and tool sessions, demos and workshops; other sessions will be posted afterward.
