Summary
This is the full opening keynote from OpenAI DevDay 2026, covering a broad slate of product and model announcements for developers and ChatGPT users. The talk opens with recent Codex updates, including Linux support, multi-folder projects, and a mobile app, before turning to its headline launch.
That launch is Dots, an always-on agent that follows a user’s access permissions and has its own cloud computer. The keynote presents it as able to take on responsibilities such as monitoring bug reports, drafting pull requests, migrating an app off a legacy API, and handling everyday tasks like scheduling and planning. Texting and calling a dot are described as coming soon, and a future in which users work with a team of dots is previewed.
On the model side, OpenAI announces GPT-6.1 Sol, positioned as a balance of cost and capability with intelligence close to Astra. It also introduces UltraFast mode across the API, ChatGPT, and Codex, described as reaching roughly 300 tokens per second, along with a new Pro 500 tier and a reopened Pro 200 plan. The Decisions API, which runs the Luna model over predefined options for near-instant responses, is also unveiled, and the keynote closes with an update on OpenAI’s AI research intern milestone.
