OpenAI announced more than 20 products and features at its September 29, 2026 DevDay, with a focus on turning ChatGPT into a platform for people and software agents. The announcements include persistent Dots, expanded plugins, new APIs and the GPT-6.1 Sol model; OpenAI says ChatGPT reaches 1.2 billion weekly users.
The most prominent consumer announcement was Dots, persistent agents powered by GPT-6 Astra. Each Dot has its own cloud computer and browser and can connect to more than 4,000 apps through plugins. OpenAI says Dots can keep several projects moving, learn a user’s preferences and work in the background. They are available to Pro and Business Premium customers in eligible markets. Enterprise, Edu and Healthcare customers can access a beta when an administrator enables it; the feature is off by default for those plans.
OpenAI also expanded the plugin system, which it presents as a way to bring reusable skills and connections to external services into ChatGPT, Codex and Dots. Changes include extensions inside ChatGPT, interactive panels, a revised creation and submission flow, improved discovery, hosted Sites for some organizations and support for MCP Events, which can trigger automations when something happens in a connected app. Eligible enterprise customers can use OpenAI Marketplace to spend part of their OpenAI commitment with 32 launch partners, including Figma, Adobe, Salesforce and ServiceNow.
Two API announcements target narrower developer needs. The Decisions API uses GPT-6 Luna to select from a finite set of answers defined by the developer; it is in limited preview. The Agents API now supports computer use, allowing agents to operate software through its interface, with OpenAI running the Codex harness. OpenAI also announced Sign in with ChatGPT for users of 16 launch partners, and GPT-6.1 Sol, which the company describes as offering near-Astra intelligence at one-fifth of Astra’s token prices.

The announcements connect OpenAI’s consumer reach to a broader set of tools for completing work. Dots can act across services, while plugins give developers and businesses a route into ChatGPT and its agent workflows. If customers ask ChatGPT to complete a task, a connected plugin may be selected to perform it, making discovery and successful task completion important for businesses that distribute software through the ecosystem.
For developers, the APIs offer ways to delegate bounded choices or let an agent work through existing software interfaces. That may reduce the need to build every workflow from scratch, but it also places more responsibility on developers to define permissions, check results and handle errors. OpenAI says Dots can make mistakes, and the company’s described safeguards—including approvals and monitoring—show that control remains part of the product design.
From Chatbot to Connected Platform
OpenAI framed the event as a move from chatbot toward agent platform, where ChatGPT serves as a shared surface for users and agents. The announcements span consumer access, enterprise administration, developer APIs and partner distribution. Dots are intended to carry out ongoing work; plugins connect them to services; and computer use lets agents act through software interfaces.
The product lineup also includes different levels of access. Dots are included for some eligible subscribers, while some enterprise features require an administrator to enable them. The Decisions API is in limited preview, and the Enterprise, Edu and Healthcare Dot beta is also controlled by administrators. Those distinctions mean the event’s announcements do not amount to general availability across all customers.
Access, Pricing and Safeguards
Several practical details remain unspecified in the supplied announcement. OpenAI has not provided a broad release date for the Decisions API, a complete market-by-market availability list for Dots, or detailed pricing for adding more Dots or buying extra speed and monthly output. The announcement says the first Dot is included in eligible plans and that chatting with it does not count toward usage limits, while tasks it starts in Codex or ChatGPT Work do.
The company describes controls such as separate cloud computers, custom rules, approval requirements, activity monitoring and the ability to pause or stop a Dot. It says sensitive actions, including changing a password, remain with the user. The supplied material does not give independent performance or security evaluations, or enough detail to assess how these protections work across every connected app. OpenAI also warns that Dots can make mistakes.
For GPT-6.1 Sol, the “near-Astra” description and one-fifth token-price comparison are OpenAI’s claims. The announcement material here does not include benchmark results, the full model lineup, or information needed to compare costs across particular workloads.
Rollouts and Developer Adoption
The next milestones depend on each product’s rollout. Developers can evaluate the Decisions API in its limited preview, while eligible Enterprise, Edu and Healthcare administrators can enable the Dots beta. OpenAI says eligible Pro and Business Premium subscribers in supported markets can use Dots now. The company has not given a general release schedule for the preview features in the supplied material.
Builders and business customers will also need to assess how the expanded plugin directory, MCP Events and Marketplace fit their workflows. OpenAI says it is piloting specialist enterprise Dots in procurement, invoice processing, email marketing, customer support and commercial contracting, and plans an integration with Microsoft Agent 365 for governance. The timing and scope of those pilots and the planned integration remain to be announced.
