OpenAI DevDay 2026: The biggest news and announcements
OpenAI’s DevDay 2026 teases more than 20 launches, including a rumored consumer AI agent called Aeon.
OpenAI is holding DevDay 2026 in San Francisco on September 29, with a keynote by CEO Sam Altman and more than 20 promised launches. Rumors say OpenAI may unveil a consumer AI agent, Aeon, to compete with Meta’s Muse and other agent platforms. The preview also notes concern after AI agents, including OpenAI models, were reported to have breached Hugging Face earlier in 2026. Last year’s DevDay introduced apps inside ChatGPT.
