OpenAI will hold OpenAI DevDay 2026 in San Francisco on September 29 US time, with CEO Sam Altman's keynote livestreamed free at 10:00 am, which is 2:00 am Japan time on September 30. OpenAI says it will show new APIs, tools, and technologies in development. Reports point to an agent that keeps working in the background, a "Managed Agents" system, and a possible $500 Pro Max plan.
OpenAI has said the keynote will cover new APIs, tools, and technologies in development, and the pre-announcement reporting has settled on agents rather than a new GPT model as the likely center of the event. Traces of an unannounced feature called "O" were reportedly found inside ChatGPT, alongside information about a "Managed Agents" system for centrally managing AI agent execution environments, Skills, Plugins, and more. Traces of a higher-tier plan called "Pro Max" at $500 per month have also been found. Fortune reports OpenAI plans a cybersecurity-focused model, "GPT-6 Cyber," within a few weeks. Whether any of it appears on stage is unconfirmed.
