TL;DR
OpenAI used its Sept. 29 DevDay to announce more than 20 products and features, including persistent Dots agents, expanded plugins and new developer APIs. The announcements point toward ChatGPT becoming a platform where users and software agents can access services and carry out tasks, though availability varies and several details remain unclear.
OpenAI announced more than 20 products and features at its Sept. 29 DevDay, including persistent agents called Dots, expanded plugins and new APIs for software developers. The launch advances the company’s effort to make ChatGPT a platform where people and agents can connect to apps and complete work; access to several features is limited or staged.
OpenAI describes a Dot as an always-on agent powered by GPT-6 Astra, with its own cloud computer and browser. Dots can connect to more than 4,000 apps through plugins and are available through ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls work now, while texting is described as forthcoming. OpenAI says the first Dot is included with eligible Pro and Business Premium plans in supported markets. Enterprise, Edu and Healthcare customers can use a beta when an administrator enables it; the feature is off by default.
The company’s examples include monitoring customer feedback and preparing tested code changes, updating a sales proposal as requirements change, and rerunning a scientific analysis as new data arrives. OpenAI says tasks initiated in Codex or ChatGPT Work count toward usage limits, while chatting with a Dot does not. Users can set rules to allow, require approval for or block actions, review an Activity View and pause or stop background work. OpenAI cautions that Dots can make mistakes, and says certain sensitive actions, such as changing a password, remain under user control.
OpenAI also announced plugin extensions inside ChatGPT, a new creator and submission process, improved discovery and support for MCP Events, which can trigger automations when something happens in a connected app. Sites can host plugins for teams using Business, Enterprise, Healthcare and Edu plans. The company said eligible enterprise customers can spend part of their OpenAI commitment through a Marketplace with 32 launch partners, including Figma, Adobe, Salesforce and ServiceNow.

The announcements could change how software companies reach customers. With plugins available to ChatGPT and Dots, an agent may select a service because it can complete a requested task, even when the user has not searched for that company by name. That makes plugin discovery, permissions and task completion consequential for businesses seeking work through ChatGPT.
For developers, the new APIs and plugin tools offer routes to build software that can classify content, route requests or act through existing interfaces. OpenAI says its Agents API can now support computer use, with OpenAI running the Codex harness. These features could broaden the tasks agents can attempt, but the announcements do not establish how reliably they will work across different applications or what costs will apply at scale.
OpenAI’s pitch also brings questions of control into routine software work. Dots can run in the background and connect to external services, while users and administrators set permissions and review activity. How well those controls work in practice will matter to organizations considering agents for tasks involving customer data, finances or business communications.
From Chatbot to Agent Platform
OpenAI framed DevDay around ChatGPT as a shared surface for people and agents, saying it reaches 1.2 billion weekly users. That figure is the company’s stated reach; the announcement does not provide a measurement method or comparison period. The broader product slate includes tools aimed at both individual users and organizations, rather than a single model release.
Alongside Dots and plugin changes, OpenAI introduced a Decisions API using GPT-6 Luna. Developers define a question and a finite list of allowed answers, then provide text or images as context; the model returns a selection that an application can use for tasks such as classification or routing. The API is in limited preview, and OpenAI said a broader release is planned, though the source material does not specify a date.
OpenAI also said users could bring an existing ChatGPT plan to 16 launch partners through Sign in with ChatGPT. The source describes this as a way for partner apps to offer a free core product with paid upgrades. On models, OpenAI announced GPT-6.1 Sol and described it as offering near-Astra intelligence at one-fifth of Astra’s token prices. That performance and price comparison is OpenAI’s claim; no independent evaluation is included in the announcement material.
Rollout, Costs and Reliability Questions
OpenAI has not provided a full availability schedule for the announcements. Dots are limited by plan and market, enterprise access depends on an administrator, and the Decisions API remains in limited preview. Texting is described as coming, without a date in the supplied material.
Several operating details are also not specified, including pricing for additional Dots or higher output, the practical limits on their tasks, and how performance varies across connected apps. OpenAI’s examples describe intended uses, not independently verified results. The source material does not provide benchmarks for GPT-6.1 Sol or detail the basis for its price comparison with Astra.
Wider Access and Developer Rollout
OpenAI says broader access to some tools will follow the initial rollout, but the supplied announcement does not give firm dates for most features. Developers and organizations will be able to assess the APIs and plugin workflow as preview access expands and more integrations become available.
OpenAI also plans a Microsoft Agent 365 integration for governance of specialist enterprise agents, which are being piloted in areas such as procurement, invoice processing, customer support and commercial contracting. The timing and capabilities of that integration remain unspecified.
