OpenAI DevDay 2026: Dots agents, GPT-6.1 models, 1.2B weekly ChatGPT users
What happened
On September 29, 2026, OpenAI held its annual DevDay at Fort Mason in San Francisco, with CEO Sam Altman hosting the keynote. It announced more than 20 products and features, centered on making ChatGPT a work operating system. The headline item is Dots, a persistent agent that handles tasks on its own, such as fixing bugs reported in Slack and sending forgotten invoices. It starts with paid ChatGPT Pro, Business Premium and Enterprise subscribers, opening in ChatGPT for eligible Pro and Business Premium users from Tuesday, launched from Codex or ChatGPT, with interaction through Slack, Teams and other platforms; SMS support is coming. On the driving model, reports say Dots runs on GPT-6 Astra, while other reports say the high-end GPT-6.1 Astra was held back over safety concerns, alongside a cheaper GPT-6.1 Sol. For Codex and the API, OpenAI added reusable cloud development environments and Codex Security Cloud repository vulnerability scanning, a code review view in the ChatGPT desktop app, and voice launch plus an /agents view in the Codex CLI. ChatGPT gained Plugin Extensions, shared workspaces called Space, collaborative Pages and Slides, Slack and Microsoft Teams integrations, automated workflows and an enterprise marketplace. OpenAI also shared usage figures: over 1.2 billion weekly active ChatGPT users, more than 35 million combined weekly users of ChatGPT Work and Codex, 2.5 million businesses using its products, and annualized revenue approaching $70 billion. On opening day, more than ten organizations protested outside the venue, chanting "People over profit" and holding signs reading "Drop the ICE contract" and "No killer robots for ICE." Later reports noted that with Codex cloud environments, agents keep working after users close their laptops, and that the environments are reusable with preloaded repositories, dependencies, scripts and settings. Analysis also argues that Dots, the new models, in-app ChatGPT recommendations and plugin extensions together push against the traditional app store model.
