GPT 官方动态

Explore more than 20 announcements from OpenAI DevDay 2026, including GPT-6 Astra, ChatGPT, Codex, APIs, security, and new tools for builders.

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.

We believe AI can help bring about a new renaissance of creativity and discovery. It should give people more time for what matters to them, more freedom to pursue their ideas, and the ability to do things they didn’t think were possible.

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.

Here’s everything we announced.

Dots are remarkably capable, always-on agents built to handle everything.They’re a whole new way to work with AI—one that gets to know what matters to you, is always working on your behalf, and takes important work off your plate so you get more of your time and attention back.

Available on Pro and Business Premium in eligible markets. Enterprise, Edu, and Healthcare users can try the beta when their workspace admin enables it; it is off by default.Learn more⁠
