OpenAI announced more than 20 products and features at its Sept. 29 DevDay, centering the releases on ChatGPT as a platform where people and software agents can work together. The slate includes persistent Dots, expanded plugins, new agent APIs and the GPT-6.1 Sol model, though several offerings are limited previews or rolling out only to selected customers.

The headline consumer product is Dots, persistent agents powered by GPT-6 Astra. Each Dot gets its own cloud computer and browser and can connect to more than 4,000 apps through plugins. OpenAI says users can reach Dots in ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls are available, while texting is planned. The first Dot is included for eligible Pro and Business Premium users in supported markets; Enterprise, Edu and Healthcare customers can access a beta when an administrator enables it.

OpenAI described Dots as agents that can keep projects moving over time, rather than respond only to one prompt. Its examples include monitoring customer feedback, preparing pull requests, revising launch plans and rerunning analyses as new data arrives. The company says users can set rules, review background activity and pause or stop an agent. Some actions require approval, sensitive tasks remain under user control, and OpenAI warns that Dots can make mistakes. Tasks launched through Codex or ChatGPT Work count toward usage limits, even though chatting with a Dot does not.

Developers also get changes to plugins and agent tools. Plugins can include reusable skills, connections to outside services through MCP servers and optional interactive interfaces. New extensions can appear in ChatGPT’s sidebar and alongside conversations; OpenAI also announced updated creation and submission tools, improved discovery, plugin-hosting Sites for organizations, and support for MCP Events that can trigger automations. The Agents API adds computer use, with OpenAI operating the Codex harness. A separate Decisions API, powered by GPT-6 Luna, returns a choice from a developer-defined set of answers and is in limited preview.

The model slate includes GPT-6.1 Sol, which OpenAI described as offering intelligence near Astra at one-fifth of Astra’s token prices. OpenAI also introduced Sign in with ChatGPT for users at 16 launch partners, allowing them to use an existing ChatGPT plan with those services. For enterprise customers, the OpenAI Marketplace has 32 launch partners, among them Figma, Adobe, Salesforce, ServiceNow and CrowdStrike.

ChatGPT Becomes an Agent Distribution Channel

The announcements give OpenAI a larger role in how software work is assigned and completed. If a user describes an outcome and an agent selects a plugin to carry it out, being discoverable inside ChatGPT could matter to businesses alongside their own apps and websites. OpenAI’s plugin directory, recommendations and permission controls will shape which services users find and authorize.

For developers and companies, the changes could reduce the effort needed to connect an agent to existing tools. Dots’ separate cloud computers and the new computer-use support extend that idea to tasks performed through software interfaces. The practical reach will depend on reliability, access permissions, costs and whether customers trust agents with ongoing work. OpenAI’s descriptions of productivity are company claims and examples, not independent evidence of results at scale.

GPT-6.1 Sol’s stated price and capability positioning may also affect the cost of building AI features, while Sign in with ChatGPT creates another route for paid services to reach users. The announcements make OpenAI’s platform ambitions clearer, but adoption and commercial impact remain to be seen.

From Chatbot to Agent Platform

OpenAI framed the announcements as a move beyond ChatGPT as a conversational product. The company said ChatGPT reaches 1.2 billion weekly users and presented it as a shared surface for people and agents. That figure is OpenAI’s stated audience metric; the announcement does not provide a measurement methodology or comparison period.

The company is building on its plugin and developer ecosystem by extending plugins across ChatGPT, Codex and Dots. It also described specialist Dots for businesses: agents with their own identity, credentials and organization-provisioned hardware. Initial pilots are planned for areas including procurement, invoice processing, customer support and commercial contracting. OpenAI has also outlined a planned integration with Microsoft Agent 365 for governance.

Rollout, Reliability and Pricing Questions

Availability is uneven. Dots are initially limited by subscription tier and market, with an administrator-enabled beta for some organizational plans. The Decisions API is in limited preview; the supplied material does not state a general release date. OpenAI said a broader release is planned, but the timing was cut off in the source material. Some enterprise capabilities are pilots, and the Microsoft Agent 365 integration is described as planned.

The announcement does not provide independent evaluations of Dots’ reliability, detailed pricing for adding agents or buying more speed and output, or results from the specialist-agent pilots. It also does not explain how the stated 1.2 billion weekly-user figure was calculated. The practical limits of app access, oversight and agent performance will become clearer as customers use the products.

Preview Releases and Business Pilots

OpenAI’s next steps are to expand access to Dots and its developer tools, progress the Decisions API beyond limited preview, and run specialist-agent pilots with business customers. The company also plans to add texting for Dots and develop its governance integration with Microsoft Agent 365. OpenAI has not supplied dates for each milestone in the source material.

Developers and customers will be watching for broader availability, product documentation and evidence about how agents perform on real tasks. Those details should clarify which features are ready for routine use, what oversight they require and how costs compare with the work they automate.
