DevDay 2026 Recap

At DevDay 2026, we’re giving people more ways to take on ambitious work and tools to build what comes next.

</>

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

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

GPT-6.1 Sol

We’re introducing GPT‑6.1 Sol, a major upgrade to GPT‑6 Sol with exceptionally strong performance on agentic coding, along with computer use, and professional work. It delivers near-Astra intelligence to everyone at a fifth of its standard input and output token prices, giving developers more flexibility to execute complex workflows within the same budget.

Available to all API, Plus, Pro, Business, Enterprise, and Edu users. Learn more⁠

Ultrafast

Ultrafast is our premium speed tier for workloads where speed matters most. Ultrafast offers up to 8× faster token generation (300 tokens per second) in Codex and up to 6x in the API.

GPT‑6 Astra Ultrafast is available today in the API⁠(opens in a new window) and in ChatGPT Work and Codex⁠(opens in a new window) on Pro 500 and Enterprise plans. GPT‑6.1 Sol Ultrafast is coming soon.

Private Intelligence

OpenAI Private Intelligence helps businesses use frontier AI with greater confidence that their data is protected. Zero Data Retention with Private Safety Processing⁠(opens in a new window) enables automated safety reviews without giving OpenAI personnel access to the underlying content. Our preview of Private Inference, coming this fall, combines confidential computing with strict, verifiable controls.

Codex in the cloud

Now developers can run Codex wherever they need it: on a computer, remotely from a phone, or in the cloud from any device. Reusable development environments help tasks start quickly and give your team a shared setup with approved settings and permissions.

Available on Plus, Pro, Business, Healthcare, Education, and Enterprise. Learn more⁠(opens in a new window)

A refreshed Codex CLI

The Codex CLI now lets you start and steer tasks with your voice. The new /agents view makes it easier to delegate work and track multiple tasks at once. We’ve also improved everyday workflows to help you edit prompts, resume sessions, and use worktrees, while a cleaner terminal UI makes longer sessions easier to read.

Available to all plans. Learn more⁠(opens in a new window)

Code Review

The new code review experience in the ChatGPT desktop app makes it easier to review changes across projects. You can read summaries, explore diffs, and ask Codex about potential issues before sharing feedback on GitHub pull requests or GitLab merge requests. With automatic reviews, Codex can also take a first pass in the cloud while you’re away.

Available on all plans. Learn more⁠(opens in a new window)

Codex Security Cloud

Codex Security Cloud gives defenders a better set of tools to harden their infrastructure. Scan entire GitHub repositories on demand or on a schedule, with ongoing checks of new commits. Codex investigates findings, removes duplicates and prepares fixes in the cloud, even with your laptop closed. It includes access to models offered through Daybreak Blue⁠ without a separate Daybreak application.

Available to all Pro, Business, Enterprise and Edu users on desktop and web. Learn more⁠(opens in a new window)

Decisions API

Decisions API enables real-time decision-making by focusing Luna's intelligence on a specific set of user-defined questions with finite pre-defined answers. Developers supply context using text or images, and get back answers they can use to classify content, route requests, or choose an agent’s next action.

Available in limited preview today with a broad release planned in the coming days.

Agents API with Computer use

The Agents API⁠ now supports computer use so developers can build agents that interact with software to complete tasks. It also brings Codex’s multi-agent capabilities, tool search, tool calling, and context compaction into your application. OpenAI runs the underlying infrastructure so your team can focus on building the application.

Available through the API and in Codex and ChatGPT Work on Pro 500 and Enterprise. Learn more⁠(opens in a new window)

Bedrock Managed Agents, powered by OpenAI

OpenAI worked with Amazon on Bedrock Managed Agents to take the core capabilities of the Agents API and add customization to work natively in AWS and integrate with AWS resources. Now you can use Bedrock Managed Agents to build OpenAI agents that run entirely in AWS. Learn more⁠(opens in a new window)

More customization in ChatGPT with plugins

Plugin extensions

We’re opening the platform we use to build ChatGPT features so developers can create their own experiences within ChatGPT. Plugin extensions let you give your plugin a home in the sidebar and build interactive panels where people can work alongside the conversation. You can also create viewers for the file types your product supports.

Available to all plans. Learn more⁠(opens in a new window)

Improved plugin creation, submission, and discovery

We’re making it easier to build plugins and help people discover them. Plugin Creator helps you build your plugin while a redesigned submission flow provides clearer feedback. Improved ranking and recommendations help people find relevant plugins in the directory and in conversations. Users choose which plugins to use and approve the access each one receives.

Available to all plans. Learn more⁠(opens in a new window)

Sites can now host plugins

You can now add supported ChatGPT plugins to the Sites you build. Teammates in your workspace can use the same app with their own connected data and permissions. We’re also making automations easier to add and manage so Sites can keep shared information up to date.

Available to Business, Enterprise, Healthcare, and Edu plans. Learn more⁠(opens in a new window)

MCP events for plugin automations

We’re adding support for the proposed MCP Events specification⁠(opens in a new window), so plugins can start automations when something happens in a connected app. For example, you can ask ChatGPT to watch for new tasks on a project board. When one comes in, ChatGPT can read the linked documents and draft a plan, even while you’re away.

Available to all plans. Learn more⁠(opens in a new window)
