OpenAI's own list of what it launched at DevDay on 29 September, in five parts. New ways of working: dots, always-on agents powered by GPT-6 Astra with a cloud computer of their own, on Pro and Business Premium first; GPT-6.1 Sol, which OpenAI says comes close to Astra at a fifth of its price; Ultrafast, a speed tier up to eight times faster in Codex; and Private Intelligence for businesses. For developers: Codex in the cloud, a Codex CLI you can steer by voice, code review in the desktop app, Codex Security Cloud, a Decisions API built on Luna, and computer use in the Agents API, which Amazon also runs as Bedrock Managed Agents. For plugins: extensions that live in ChatGPT's sidebar, a new submission flow, plugins inside Sites, and MCP events that start automations. For teams: ChatGPT Space, Pages, shared slides, team tasks, @ChatGPT in Slack and Teams, a Meetings plugin and shareable profiles. For subscribers: Sign in with ChatGPT across 16 partner tools, a Pro 500 tier at 25 times the Plus allowance, and an OpenAI Marketplace where an enterprise's OpenAI commitment can pay for partner software.
From OpenAI
DevDay 2026 is our biggest yet, with more than 20 major announcements across ChatGPT, Codex, our models, and entirely new forms of working with AI.
Today, we introduced agents that can take on ongoing responsibilities and new ways for people and AI to work together. We also expanded our commitment to an open ecosystem by opening up ChatGPT as a shared surface where humans and agents can collaborate and where developers can directly launch new native experiences to our collective 1.2B weekly users.
