OpenAI DevDay 2026 Adds Agent APIs, Cloud Codex and GPT-6.1 Sol

OpenAI expands agent and model capabilities

OpenAI announced a series of product and developer updates at DevDay 2026, including GPT-6.1 Sol, computer use for the Agents API, cloud-based Codex environments, a Decisions API, new ChatGPT plugin capabilities, Dots and ChatGPT Space.

The Agents API now supports computer use, allowing applications to operate software through graphical interfaces. It incorporates multi-agent capabilities from Codex, tool search, tool calling and context compaction, with OpenAI managing the underlying execution infrastructure. The functionality is available through the API and in Codex and ChatGPT Work for selected plans.

GPT-6.1 Sol is an update to GPT-6 Sol aimed at coding, computer use and professional tasks. OpenAI says the model approaches GPT-6 Astra on several evaluations while charging one-fifth of Astra's standard input and output token prices. Cached input costs $0.10 per million tokens. The model is available through the API, ChatGPT Work and Codex.

Codex adds cloud environments and review workflows

Codex can now run in cloud environments in addition to local computers, allowing developers to start remote tasks from other devices. The Codex CLI was updated with voice input and an /agents interface for delegating and monitoring multiple tasks.

A new code-review workflow can analyze diffs and potential issues in GitHub pull requests and GitLab merge requests. Codex Security Cloud can scan repositories and new commits, investigate findings, remove duplicates and prepare fixes.

Decisions, plugins and persistent workspaces

The Decisions API is currently in limited preview. It uses the smaller Luna model to select from a predefined set of answers based on text or image context. OpenAI positions the API for classification, request routing and choosing an agent's next action.

OpenAI expanded ChatGPT's plugin system. Developers can now build sidebar experiences, interactive conversation panels and custom file viewers. Plugins can also respond to events through the proposed MCP Events specification, allowing automations to start when an event occurs in a connected application.

DevDay also introduced Dots, persistent agents that can work on ongoing tasks, and ChatGPT Space, a shared workspace where teams and agents can work with common context. Community discussion focused on the emphasis on agents and developer infrastructure. Developers highlighted computer use, cloud-based Codex and lower-cost models as practical additions, while others questioned whether the releases represented significant advances over capabilities already available across existing agent platforms.

Together, the announcements extend OpenAI's platform from individual model calls toward persistent agents that can use tools, operate software, collaborate and execute tasks remotely. The releases cover autonomous agents, lower-cost models, cloud-based coding and expanded ChatGPT integrations.
