TL;DR
OpenAI used DevDay on Sept. 29 to announce more than 20 products and features, positioning ChatGPT as a platform for people and AI agents. The briefing highlighted persistent Dots, expanded plugins, new agent and decision APIs, and GPT-6.1 Sol; availability and capabilities vary, and some details remain unclear.
OpenAI announced more than 20 products and features at its Sept. 29 DevDay, making persistent AI agents and software integrations central to its pitch for ChatGPT. The company said ChatGPT reaches 1.2 billion weekly users and presented the service as a shared workspace for people and agents, a strategy that could change how software companies reach customers and automate work.
The most prominent consumer announcement was Dots, persistent agents powered by GPT-6 Astra. OpenAI says each Dot has its own cloud computer and browser, can work across more than 4,000 apps through plugins, and can keep several projects moving. Users can access Dots through ChatGPT on desktop, the web and mobile, as well as Slack and Teams. Voice calls are available; texting is described as forthcoming.
Dots are available to Pro and Business Premium subscribers in eligible markets, according to the briefing. Enterprise, Edu and Healthcare customers can use a beta if an administrator enables it; it is off by default. The first Dot is included with the plan, but work it starts in Codex or ChatGPT Work counts toward usage limits. OpenAI says users can set rules requiring approval for certain actions, review background activity, and pause or stop an agent. The company also warns that Dots can make mistakes.
OpenAI also expanded plugins, which it describes as reusable skills and connections to outside services, with optional interactive interfaces. New features include extensions in ChatGPT, a revised creation and submission process, improved discovery, Sites for teams, and support for MCP Events that can trigger automations from activity in connected apps. The company named 32 launch partners for its OpenAI Marketplace, including Figma, Adobe, Salesforce and ServiceNow.

The announcements point toward a shift in how users find and operate software. OpenAI’s presentation framed an agent as selecting a service to complete a task, potentially before a user knows which company provides it. If that model takes hold, developers may compete for selection inside an AI assistant as well as for direct customer attention. OpenAI’s plugin directory, recommendations and permission controls would then help determine which services an agent can use.
For businesses, the appeal is automation across existing applications rather than moving every task into a single product. OpenAI says Dots can monitor feedback, update work as requirements change and prepare materials for review. These are company examples, not independent evidence of performance. The need for human approval on sensitive actions and the warning that agents can err show that oversight remains part of the product design.
From Chatbot to Agent Platform
OpenAI’s DevDay briefing described ChatGPT as a platform connecting users, agents and software. Dots are its personal-agent offering; the company also outlined specialist Dots for organizations, with separate identities, credentials and IT-provisioned hardware. OpenAI said pilots are starting in areas such as procurement, invoice processing, customer support and commercial contracting, with a planned Microsoft Agent 365 integration for governance.
The developer announcements extend the same approach. The Agents API now supports computer use, allowing agents to operate software through its interface; OpenAI says it runs the Codex harness. The Decisions API applies GPT-6 Luna to narrow choices from a list defined by the developer and is in limited preview. Sign in with ChatGPT lets users use an existing plan with 16 launch partners. The briefing also introduced GPT-6.1 Sol, which OpenAI described as offering near-Astra intelligence at one-fifth of Astra’s token prices. These are company descriptions; comparative performance details were not included in the supplied material.
Availability and Performance Details
The announcement leaves open how quickly Dots and the other products will reach broader markets. The briefing names eligible plans and says access varies by market, while enterprise-related features include betas and pilots. It does not give a complete rollout schedule, pricing for additional Dots or faster output, or details on when texting will arrive.
It is also not clear from the supplied material how well Dots perform across the many connected apps, what safeguards apply in every integration, or how GPT-6.1 Sol’s cost and capability comparison was measured. OpenAI’s examples and product descriptions are company claims; independent results and customer experience were not provided.
Rollouts and Preview Expansions
OpenAI says the Decisions API is in limited preview and that a broader release is planned, though the supplied briefing cuts off before giving a complete timeframe. Dots are rolling out to eligible subscribers, while enterprise customers can access a beta when administrators enable it. The specialist-agent pilots and planned Agent 365 integration will be important next steps for judging how the company handles organizational oversight.
Developers and customers will also be watching plugin submissions, marketplace access and MCP Events as those features reach more users. OpenAI has not supplied dates for every rollout. Availability, performance and pricing details are expected to become clearer as the products move beyond announcement, preview and pilot stages.
