OpenAI announced more than 20 products and features at its DevDay on Sept. 29, 2026, positioning ChatGPT as a platform where people, agents and third-party software can work together. The announcements include persistent Dots agents, expanded plugins, new developer APIs and a sign-in option for partner apps, with access and availability differing across products.

OpenAI described Dots as persistent agents powered by GPT-6 Astra, each operating with its own cloud computer and browser. The company says a Dot can work across several projects, retain preferences over time and connect to more than 4,000 apps through plugins. Users can access Dots in ChatGPT on desktop, the web and mobile, as well as Slack and Teams. Voice calls are available, while texting is still to come.

Availability is tiered. OpenAI says the first Dot is included for Pro and Business Premium customers in eligible markets. Enterprise, Education and Healthcare customers can use a beta if an administrator enables it; the feature is off by default. Chatting with a Dot does not count toward usage limits, but tasks it starts in Codex or ChatGPT Work do. OpenAI says users may later add Dots or purchase additional speed and monthly output for each one.

The company also expanded the plugin system, adding extensions inside ChatGPT, interactive panels, file viewers, a creator and submission flow, improved discovery and the ability for Sites to host plugins. Support for the proposed MCP Events specification lets plugins trigger automations when events occur in connected apps. Separately, the Decisions API, now in limited preview, uses GPT-6 Luna to select from a developer-defined set of answers. The Agents API gains computer use, with OpenAI running the Codex harness. “Sign in with ChatGPT” lets users bring an existing plan to 16 launch partners, according to the source material.

Agents Move Into Daily Software

The announcements could change how software companies reach customers and automate routine work. OpenAI says Dots can monitor feedback, revise work as requirements change and prepare outputs such as pull requests or sales proposals. Those are company examples, not independently established performance results. If customers ask ChatGPT to complete a task and a plugin carries it out, businesses may be selected based on whether their integrations can complete that task, rather than on whether a user already knows their brand.

For developers, plugins become a distribution route as well as a way to connect services. Better discovery and in-conversation integrations may help users find tools, while approval controls give users a say over what each plugin can access. The Decisions API offers a narrower route to automation: an application can ask a model to choose among permitted outcomes for routing or classification. Its limited-preview status means wider availability and performance remain untested publicly.

Persistent agents also raise practical questions about oversight. OpenAI says Dots run on separate cloud computers, can use saved passwords without exposing them to the model, and limit background proactive research to read-only tools. Custom Rules can allow, require approval for or block actions, and users can monitor or stop work. The company still warns that Dots can make mistakes, and says sensitive actions such as changing a password remain with the user.

From ChatGPT to Agent Platform

OpenAI framed the event as a shift from ChatGPT as a chatbot toward a shared surface for people and agents. It cited 1.2 billion weekly users for ChatGPT; the source material does not provide a measurement period or comparison baseline for that figure. The event included a broader slate of product and model announcements, but the supplied details focus on agents, plugins and APIs.

The plugin expansion links ChatGPT, Codex and Dots to external services through integrations that can include reusable skills, MCP server connections and optional user interfaces. OpenAI also announced an enterprise Marketplace where eligible customers can spend part of their OpenAI commitment with 32 launch partners, including Figma, Adobe, Salesforce, ServiceNow, Harvey, CrowdStrike and Baseten. Sites hosting plugins are aimed at organizations where staff use a shared app with their own data and permissions.

For businesses, OpenAI described specialist Dots as agents with separate identities, credentials and IT-provisioned hardware. Initial pilots are planned for procurement, invoice processing, email marketing, customer support and commercial contracting. OpenAI also plans a Microsoft Agent 365 integration for governance. The supplied material does not give a date for that integration.

Access and Rollout Remain Limited

Several details remain unsettled. The Decisions API is in limited preview, and the source material cuts off before the promised broad-release timing. Texting with Dots is described as forthcoming without a date. Eligibility for consumer access depends on plan and market, while enterprise beta access requires an administrator to enable the feature.

OpenAI’s examples of Dots completing work are company descriptions, and the supplied material does not include independent results on reliability, time saved or error rates. It also does not specify how much later Dots, additional speed or monthly output will cost. The longer-term availability of specialist Dots and the Microsoft Agent 365 integration is not dated.

Previews and Pilots Set the Pace

The next milestones are the expansion of the Decisions API beyond limited preview, the arrival of Dot texting and further rollout to eligible customer groups. OpenAI says specialist Dots will begin with pilots across five business functions and has plans for governance integration with Microsoft Agent 365. No launch dates or pilot results are provided in the source material, so the timing and scope of broader access remain open.
