DevDay 2026: computer use comes to the Agents API, plus a Decisions API for routing
OpenAI's developer event was heavy on agent plumbing: GUI-driving agents, cloud Codex environments, a classification endpoint billed on input only, and a plugin event spec.
OpenAI used DevDay 2026 to ship a batch of developer updates aimed squarely at teams building agents, according to InfoQ's recap.
What shipped
- GPT-6.1 Sol: a model aimed at coding, computer use, and professional tasks, with cached input priced at $0.10 per million tokens. Available in the API, ChatGPT Work, and Codex.
- Agents API with computer use: applications can now operate software through graphical interfaces, with multi-agent orchestration, tool search, and tool calling handled by OpenAI's infrastructure.
- Cloud Codex environments: tasks can run remotely and be kicked off from other devices. The CLI added voice input, an /agents interface for delegating work, GitHub pull-request review, and repository security scanning.
- Decisions API (limited preview): uses the smaller Luna model to pick from a predefined set of answers given text or image context. AI Weekly reports it returns typed answers with confidence scores and charges only for input tokens at $0.10 per million.
- ChatGPT plugins: sidebar experiences, interactive panels, custom file viewers, and support for the proposed MCP Events spec for event-driven automations.
- Dots (persistent agents for ongoing tasks) and ChatGPT Space (a shared team workspace with common context).
What it means for your stack
DiscussTried a computer-use agent on a legacy app? Tell the thread what broke.The Decisions API is the sleeper here. A cheap, typed classification endpoint with confidence scores is exactly the primitive most routing and triage pipelines hand-roll today. Computer use in the Agents API, meanwhile, moves "drive the legacy app with an agent" from a research demo to something you can budget for, which is also when governance questions get real.
GPT-6 lands in ChatGPT with an interface that builds itself
OpenAI is rolling out GPT-6 Sol and Luna with "Intelligent UI," which answers with buttons, charts, and small working tools instead of a wall of text. Here is what changes for teams that standardised on ChatGPT.
