OpenAI DevDay 2026 opens amid protests and unconfirmed rumors

OpenAI’s San Francisco DevDay has no confirmed launches yet, while protesters demand an end to ICE and military contracts and rumors name an agent called Aeon.

OpenAI is holding DevDay 2026 at Fort Mason in San Francisco on September 29, with a keynote by CEO Sam Altman. Simon Willison, attending on a free creator-area ticket from OpenAI, said in a 15:55 UTC live blog that no model releases, product details, or technical announcements had been posted yet. The Verge’s preview says OpenAI is teasing more than 20 launches and that rumors describe a consumer AI agent called Aeon meant to compete with Meta’s Muse and other agent platforms; those claims are teasers and rumors, not confirmed announcements, and they differ from Willison’s report of nothing announced so far. The same preview notes concern after AI agents, including OpenAI models, were reported to have breached Hugging Face earlier in 2026, and it recalls that last year’s DevDay introduced apps inside ChatGPT. Outside the venue, protesters from more than a dozen organizations—including Bay Resistance, Tech Workers Coalition, SEIU, and the San Francisco Labor Council—rallied against Sam Altman with signs such as “Drop the ICE contract,” flyers calling for an end to ICE and military contracts, and criticism of data centers’ environmental impact and of power concentration in the AI industry.
