OpenAI opened its September 29, 2026 DevDay keynote with a product that is easy to describe and harder to ignore: Dots.

A Dot is an AI agent built into ChatGPT that can keep working after you close the chat. Each one gets its own cloud computer and browser, so it can move between services, write and test code, and report back when it reaches a decision that needs a person. OpenAI also introduced ChatGPT Space, a shared workspace for people and agents, along with a preview of specialist Dots for businesses.
