TL;DR
At its Sept. 29 DevDay, OpenAI announced more than 20 products and features, including persistent Dots agents, expanded plugins and APIs for agent tasks and bounded decisions. The announcements point toward ChatGPT becoming a platform where people and agents use connected software, though access, pricing and rollout details vary by product.
Dots are persistent agents powered by GPT-6 Astra, each operating through its own cloud computer and browser. OpenAI says they can connect to more than 4,000 apps through plugins and can work across ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls are available, while texting is still planned.
Dots are available to Pro and Business Premium customers in eligible markets, according to the announcement. Enterprise, Edu and Healthcare customers can access a beta if an administrator enables it; the feature is off by default. The first dot is included with a plan. OpenAI says conversations with a dot do not count toward usage limits, although tasks it launches in Codex or ChatGPT Work do. The company also described specialist dots for business pilots in areas such as procurement, invoice processing and customer support.
OpenAI also expanded plugins, which can combine reusable skills, connections to external services through MCP servers and optional interactive interfaces. New plugin extensions can appear in ChatGPT’s sidebar or alongside conversations. A revised creator and submission process, improved discovery, sites that host plugins and support for MCP events are among the changes. MCP events can trigger automations when something happens in a connected service, such as a new project-board task.
Two API updates target specific agent tasks. The Decisions API uses GPT-6 Luna to select from a developer-defined list of answers, based on text or image context; OpenAI says 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 16 launch partners, allowing users to bring an existing plan to participating apps.
The model slate includes GPT-6.1 Sol. The source material describes it as offering near-Astra intelligence at one-fifth of Astra’s token prices. OpenAI also named Ultrafast and Pro 500, but the material available here does not give their specifications. Eligible enterprise customers can also spend part of their OpenAI commitment through a marketplace with 32 launch partners, including Figma, Adobe, Salesforce and ServiceNow.

The announcements connect agents, software integrations and developer tools inside ChatGPT. If users ask an agent to complete a task, plugins could determine which outside service handles it. That gives developers and businesses a new potential distribution channel, while making plugin discovery and permissions consequential: users choose which plugins to enable and approve their access.
For companies, persistent agents could take on recurring work across connected tools. OpenAI’s examples include tracking customer feedback, updating proposals and rerunning analyses as new data arrives. Those examples describe intended uses, not independently verified performance. The extent to which organizations adopt the tools will depend on reliability, oversight, access controls and costs as well as convenience.
The product also extends OpenAI’s reach beyond ChatGPT itself. Specialist dots, enterprise marketplace access and a planned Microsoft Agent 365 integration suggest a push into workplace operations and governance. The event’s reach claims and product announcements do not, by themselves, show how much work agents can safely complete in practice.

From Chatbot to Connected Agents
OpenAI framed DevDay around a shift from ChatGPT as a chatbot toward a shared surface for people and agents. Its announcement said ChatGPT has 1.2 billion weekly users; the source material does not specify the measurement method or period behind that figure.
The plugin updates build on existing connections between ChatGPT and outside services, adding interactive interfaces and event-triggered workflows. OpenAI’s developer materials also list conversion specifications for tasks such as restaurant reservations, quote requests and product checkout, and a guide for submitting a Claude Code plugin. These details indicate an effort to make the plugin directory work across more kinds of agent-driven tasks.
OpenAI described Dots as autonomous but subject to user controls. Custom Rules can allow, require approval for or block actions; an Activity View displays background work; and users can pause or stop monitoring. OpenAI says background proactive research is limited to read-only tools, sensitive tasks such as password changes remain with the user, and Dots can make mistakes.
Rollout, Pricing and Reliability Questions
Several details remain open. The source material does not give a general release date for the Decisions API, which is in limited preview, or fuller specifications for Ultrafast and Pro 500. It also does not explain how GPT-6.1 Sol’s stated price comparison was measured, or provide benchmark results supporting the description of its capabilities.
OpenAI has not established how reliably Dots will handle long-running work, what expanded use will cost, or how broadly the features will be available across markets and plans. The announcement says users may later add Dots or buy more speed and monthly output per Dot, without providing prices. The extent of the stated 1.2 billion weekly reach and the terms for partner integrations also need further detail.
Previews and Partner Rollouts
OpenAI’s next steps include expanding access to Dots and plugin features, continuing the Decisions API limited preview, and bringing Sign in with ChatGPT to its 16 launch partners. Enterprise pilots for specialist Dots are starting in selected business functions, with a Microsoft Agent 365 integration planned for governance.
Developers and customers will be able to judge the announcements as release details, pricing, partner availability and product documentation emerge. OpenAI has not provided a full public timeline for those rollouts in the source material.
