OpenAI DevDay 2026 announces Dots and GPT-6.1 Sol
What happened
On 29 September 2026, OpenAI held DevDay 2026 at Fort Mason in San Francisco. Ahead of the event, The Verge reported that OpenAI was trailing in consumer AI agents and expected it to unveil its own agent, Aeon, competing with Meta’s Muse, SpaceX’s Grok Bot and OpenClaw. OpenAI later published an official recap covering more than 20 updates across GPT-6 Astra, ChatGPT, Codex, APIs and safety, but provided only an overview. Simon Willison liveblogged the keynote. From 30 September, TechCrunch and The Decoder reported that ChatGPT plugins had expanded into app-like experiences with a sidebar entry, interactive panels and file viewers, and that Codex had introduced cloud development environments reusable across devices. ChatGPT also gained the Plugin Extensions system, shared Space, collaborative Pages and Slides, Slack and Microsoft Teams integrations, automated workflows and an enterprise marketplace. TechCrunch said colleagues in Space could collaborate with chatbots and the new agent role Dots. OpenAI announced more than 1.2 billion weekly active ChatGPT users, over 35 million combined weekly active users for ChatGPT Work and Codex, and 2.5 million enterprise customers. Latent Space reported the launches of persistent Dots agents, GPT-6.1 Sol, Ultrafast mode, the Decisions API, ChatGPT Spaces and Marketplace. Earlier reports expected Aeon, whereas later reports described Dots; the initial official recap mentioned GPT-6 Astra, while later reports named GPT-6.1 Sol.
