OpenAI announced 25 named releases and updates at DevDay in San Francisco on 29 September 2026, according to its event recap. The largest changes are dots, agents designed to keep working on a person’s behalf; GPT-6.1 Sol, a lower-priced model for complex work; and new tools for developers building agents and software. The rest of the programme reaches across Codex, plugins, shared workspaces and subscription plans.

The event programme set Sam Altman’s opening keynote for 10am Pacific time, followed by technical sessions, workshops and a closing session. OpenAI’s published recap is the record for the announcement list below. Availability varies sharply: some products are rolling out today, others are in preview, and several are due later.

During a question-and-answer session, Altman said OpenAI was investing more in agent safety, security and monitoring, the Associated Press reported. The agency also reported that OpenAI had paused a separate advanced model’s release after researchers raised security concerns the day before DevDay.

Dots can keep working between conversations

Dots are OpenAI’s new agents for ongoing work. Each has its own cloud computer and can use connected apps to pursue tasks over time. A user can inspect the computer, give feedback and set permissions. OpenAI says a dot’s background research uses connected tools with read-only access; actions with wider effects are governed by rules and review controls described in its dots announcement.

Dots are rolling out to Pro and Business Premium users in eligible markets. Enterprise, Education and Healthcare workspaces can try a beta when an administrator enables it. OpenAI also previewed specialist dots for organisations, with separate identities and defined responsibilities, and said it is working with Microsoft to bring their governance into Agent 365.

GPT-6.1 Sol costs $2 per million input tokens

GPT-6.1 Sol is available from 29 September in the API, ChatGPT Work and Codex. OpenAI’s model announcement lists standard API prices of $2 per million input tokens, $0.10 per million cached input tokens and $10 per million output tokens. The company says the model approaches GPT-6 Astra on several coding, computer-use and professional-work evaluations at about one-fifth of Astra’s standard token price. Those are OpenAI’s reported test results, and the performance difference depends on the task and evaluation setting.

The model is available to Plus, Pro, Business, Enterprise and Education users in Work and Codex. OpenAI says GPT-6.1 Sol is due in Chat later. A separate Ultrafast tier offers up to eight times faster token generation in Codex and six times in the API for selected workloads: GPT-6 Astra Ultrafast is available today in the API, Work and Codex on Pro 500 and Enterprise, while the Sol version is coming soon.

Developers received new agent tools

OpenAI added tools for building agents that make defined choices and operate software. Decisions API uses a user’s finite set of answers to classify or route inputs. The Agents API now supports computer use and adds multi-agent capabilities, tool search, tool calls and context compaction. OpenAI also announced an Amazon collaboration that brings those capabilities into Bedrock Managed Agents for AWS users.

Announcement What OpenAI says it does Availability
Decisions API Answers bounded, user-defined questions from text or image context. Limited preview now; broader release planned in the coming days.
Agents API with computer use Lets developers build agents that interact with software and coordinate tools. API access; also in Codex and ChatGPT Work on Pro 500 and Enterprise.
Bedrock Managed Agents Runs OpenAI-powered agents within AWS with AWS integrations. Announced with Amazon.
Private Intelligence Adds privacy controls for business AI work, including automated safety review under Zero Data Retention. Private Inference preview planned for autumn 2026.
Ultrafast Premium speed tier for Astra, with Sol to follow. Astra available now on eligible API and subscription plans.

These descriptions and rollout terms come from OpenAI’s recap. The key distinction for a developer is which features can be used immediately and which require a preview or higher plan.

Codex gained cloud work, review and security tools

OpenAI expanded Codex from a local coding interface into cloud and remote workflows. Developers can run tasks from a computer or phone, use reusable development environments and review changes in the ChatGPT desktop app. The CLI gained voice input, an agents view and workflow improvements. Codex Security Cloud can scan repositories and prepare investigated fixes.

Announcement What changed Availability
Codex in the cloud Tasks can run remotely from any device with shared development environments. Plus, Pro, Business, Healthcare, Education and Enterprise.
Refreshed Codex CLI Voice input, an agents view, improved prompt editing, session resume and worktrees. All plans.
Code Review Desktop review of changes and cloud first-pass reviews for GitHub and GitLab work. All plans.
Codex Security Cloud Repository scans with investigated findings and proposed fixes. Pro, Business, Enterprise and Education on desktop and web.

Plugins gained a place in the interface

Plugin extensions can now add sidebar homes, interactive panels and file viewers to ChatGPT. OpenAI also announced a revised Plugin Creator, a clearer submission process, and ranking and recommendations to help people discover plugins. Supported plugins can run inside Sites, while proposed MCP Events support would let connected app events start automations. The plugin releases and availability are set out in the DevDay recap.

Announcement What it adds Availability
Plugin extensions Sidebar entries, interactive panels and file viewers. All plans.
Plugin creation and discovery Updated creator, submission flow and directory recommendations. All plans.
Plugins in Sites Shared site experiences with each teammate’s connected data and permissions. Business, Enterprise, Healthcare and Education.

ChatGPT gained shared workspaces and documents

ChatGPT Space is a shared workspace for people, ChatGPT and dots to build on team knowledge. Pages are documents people and agents can edit together; interactive collaborative slides are planned. OpenAI also introduced team tasks, @ChatGPT in Slack and Microsoft Teams, a Meetings plugin, shareable profiles and Sign in with ChatGPT for outside tools.

Announcement What it does Availability
ChatGPT Space Shared knowledge and projects for teams and dots. Pro, Business and Enterprise on desktop and web; mobile can find, read and share pages.

OpenAI’s published list also includes a Pro 500 plan, with a usage allowance described as 25 times the ChatGPT Plus allowance, and an OpenAI Marketplace programme through which eligible enterprise customers can apply part of an existing OpenAI commitment to approved partner software. The company names 32 initial marketplace partners.

The day adds several ways for people to assign work to AI and for developers to put agents into applications. What a reader can use today depends on the product, country, subscription and whether a preview has opened.
