OpenAI announced more than 20 products and features at its DevDay on Sept. 29, 2026, putting persistent agents, software integrations and developer tools at the center of its effort to make ChatGPT a shared surface for people and agents. The announcements include Dots, agents that can work through software interfaces, expanded plugins and APIs for narrow decisions; access ranges from current paid-plan availability to limited previews and enterprise pilots.

The most prominent consumer-facing announcement is Dots, persistent agents powered by GPT-6 Astra. Each dot has a separate cloud computer and browser, can connect to more than 4,000 apps through plugins, and can keep several projects moving. OpenAI says users can reach dots through ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls are available, while texting is described as coming later.

Dots are available to Pro and Business Premium customers in eligible markets, with the first dot included in the plan. Enterprise, Edu and Healthcare customers can use a beta when an administrator enables it; the feature is off by default. OpenAI says chatting with a dot does not count toward usage limits, but work it starts in Codex or ChatGPT Work does. The company may later offer additional dots or more speed and monthly output per dot.

OpenAI also announced plugin extensions inside ChatGPT, a revised creator and submission process, improved discovery, Sites for hosting plugins and support for MCP events that can trigger automations. The Agents API now supports computer use, with OpenAI running the Codex harness. The Decisions API, which applies GPT-6 Luna to choices from a developer-defined list, is in limited preview. Sign in with ChatGPT is available to users of 16 launch partners, allowing them to use an existing plan with those services.

How Agents Could Reach Customers

The announcements point to a change in how software companies may reach users: ChatGPT could select a service based on the task a user asks it to complete. OpenAI’s plugin system gives businesses a route into ChatGPT, Codex and Dots, while plugin discovery and permissions shape which services an agent can use. For developers, distribution may depend on whether a plugin is selected and completes the requested work, as well as on a user’s familiarity with the business behind it.

The APIs target different parts of that process. The Decisions API is designed for constrained choices, such as classifying content or routing a request, while computer use lets an agent operate software through its interface. These capabilities could help developers connect decisions and actions in existing products. The announcements do not establish how reliably they will work across tasks or what costs and limits will apply broadly.

For organizations, specialist dots are a proposed way to assign agents defined responsibilities with their own identities, credentials and IT-provisioned hardware. OpenAI is beginning pilots in procurement, invoice processing, email marketing, customer support and commercial contracting. The planned Microsoft Agent 365 integration is intended to address governance, but the announcement gives no deployment results.

From Chatbot to Agent Platform

OpenAI framed the event as a move from chatbot toward an agent platform and said ChatGPT reaches 1.2 billion weekly users. That audience figure is the company’s claim; the source material does not provide a measurement method. The announcements span consumer agents, enterprise pilots and developer tools, rather than describing a single product launch.

Plugins are central to the plan. A plugin can bundle reusable skills, connections to external services through MCP servers and an optional interface, then be published to a shared directory. OpenAI says plugin extensions can add interactive panels and file viewers in ChatGPT; Figma and Adobe demonstrated integrations. Sites are intended to let teams use the same app while keeping their own connected data and permissions in Business, Enterprise, Healthcare and Edu plans.

OpenAI also named 32 launch partners for an enterprise marketplace where eligible customers can spend part of their OpenAI commitment. The listed partners include Figma, Adobe, Salesforce, ServiceNow, Harvey, CrowdStrike and Baseten. Separately, OpenAI described GPT-6.1 Sol as offering near-Astra intelligence at one-fifth of Astra’s token prices. That is a company characterization, and the available source material provides no benchmark results or fuller model specifications.

Availability, Limits and Reliability

Access differs by product and customer type. The source material does not specify all eligible markets for Dots, a general release date for the Decisions API, or a launch timeline for several plugin features. Texting is described as forthcoming, without a date. It also remains unclear how the first dot’s included access compares with future paid options.

OpenAI warns that Dots can make mistakes. The company describes controls including Custom Rules to allow, require approval for or block actions; an Activity View for background work; and monitoring that can pause or stop a dot. Background proactive research is limited to read-only tools, and sensitive actions such as changing a password remain with the user. These controls address some risks, but the source material gives no independent evaluation of agent accuracy, security or performance at scale.

The source material also cuts off during its description of the Decisions API, so it does not provide the full set of release details. It offers no complete pricing, usage limits or technical specifications for the announced products. Claims about model performance, user reach and business impact should be read as OpenAI’s statements unless supported by separate evidence.

Rollouts and Enterprise Pilots

Users in eligible markets can try Dots on supported plans, while enterprise administrators can decide whether to enable the beta for their organizations. Developers can watch for further access details on the Decisions API and updates to the plugin creator and submission process. OpenAI has not supplied a broad-release date for the limited-preview API in the material available here.

OpenAI says it is starting specialist-dot pilots in five business areas and plans an integration with Microsoft Agent 365 for governance. The practical next milestones are whether those pilots expand, how organizations manage agent identities and permissions, and whether the integrations perform reliably in day-to-day work. The announcements describe intended capabilities; adoption and results remain to be seen.
