OpenAI used DevDay 2026 to announce a broad set of updates spanning models, autonomous agents, coding tools, APIs and team collaboration.

The event took place in San Francisco on 29 September and included new capabilities such as Dots, GPT-6.1 Sol, computer use in the Agents API and expanded Codex workflows.

Dots: always-on agents

OpenAI describes Dots as persistent agents that can work on a user's behalf and connect to apps and a cloud computer. They are designed for ongoing work rather than a single chat session.

Availability is plan-dependent. OpenAI says Dots are available on Pro and Business Premium in eligible markets, while Enterprise, Edu and Healthcare access is controlled through workspace-admin beta settings.

GPT-6.1 Sol

OpenAI also released GPT-6.1 Sol for complex coding and professional work. The API changelog says the model is available in the Responses and Chat Completions APIs and supports multi-agent delegation in beta.

Codex moves further into the cloud

Codex Cloud lets developers start and continue coding tasks across desktop, web and mobile using reusable environments with repositories, tools and dependencies. OpenAI also highlighted code-review and security workflows designed to make long-running software tasks easier to manage.

Computer use arrives in the Agents API

The Agents API now includes computer use, allowing agents to operate software through a hosted browser environment. Applications remain responsible for controlling website access, sign-in and verification boundaries.

ChatGPT gets more collaborative

DevDay also highlighted ChatGPT Space, Pages, team tasks, plugin extensions and collaboration features. The common theme is that ChatGPT is becoming a workspace where people, agents and connected tools can work together over longer periods.

Availability varies

Not every announcement is universally available. Some features are in beta, some are limited to specific paid plans or workspaces, and others have staged rollouts. Businesses should check product documentation before assuming a feature is ready for organisation-wide deployment.

Bottom line

DevDay 2026 showed OpenAI pushing beyond chat into persistent agents, cloud coding, tool use and shared workspaces. For developers, the most important question is no longer only which model is strongest; it is how models, tools, permissions and long-running workflows fit together safely in production.
