OpenAI DevDay 2026: The biggest news and announcements

It’s OpenAI’s turn in the fall tech events calendar. The company is hosting its annual DevDay on September 29th in San Francisco, starting with a live keynote featuring CEO Sam Altman. The company is teasing “20+ launches” with Altman saying that “we have found a new thing,“, and rumors suggest it could launch a consumer AI agent to rival Meta’s Muse. The keynote begins at 1PM ET / 10AM ET, and you can watch it on OpenAI’s website here.DevDay is happening at a tumultuous moment for OpenAI. The AI industry has been rocked by revelations of agents hacking outside companies, including OpenAI’s own models, which breached Hugging Face earlier this year. The hacks kicked off a broader conversation about a potential AI development slowdown. So in addition to new products, Altman and others at OpenAI could use DevDay to discuss the company’s latest stance on AI safety as well.You can follow all of our coverage of DevDay 2026 right here.OpenAI’s AI agents need to catch upImage: Cath Virginia / The Verge, Getty ImagesOpenAI popularized the modern generative AI chatbot, but as its 2026 DevDay event approaches, it’s fallen behind in one of the industry’s hottest categories: continuously running, consumer-facing AI agents. On Tuesday, it will likely try to capture the lead in that race. Rumors abound that OpenAI will release its own AI agent, dubbed Aeon — its answer to Meta’s Muse, SpaceX’s Grok Bot, OpenClaw, and many more.Aeon could have a shot at success, but to beat the competition, it would need to pull together the best features of several different agent platforms. The ideal system would be as useful as the open-source OpenClaw, as cheap and easy to set up as Meta’s Muse, and as simple to chat with as the up-and-coming Instinct. Conversely, it would aim to solve the serious security risks that have plagued agents since the rise of OpenClaw and only continued with Muse.Read Article >OpenAI’s DevDay 2026 has a date.Mark your calendars for September 29th.
