TL;DR
OpenAI used its Sept. 29 DevDay to announce more than 20 products and features focused on agents, plugins and developer tools. The announcements include persistent Dots, new API capabilities and GPT-6.1 Sol, though some details and availability remain limited or unspecified.
The headline consumer product 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 work across projects over time. OpenAI says users can reach them through ChatGPT on desktop, the web and mobile, as well as Slack and Teams. Voice calls are available, while texting is planned. The initial rollout covers Pro and Business Premium customers in eligible markets; Enterprise, Edu and Healthcare customers can use a beta when an administrator enables it.
OpenAI says a first dot is included with the plan and that chatting with it does not count toward usage limits. Tasks it starts in Codex or ChatGPT Work do count. The company describes controls including custom rules to allow, require approval for or block actions, an activity view, and options to pause or stop a dot. Some actions, such as changing a password, remain for the user. OpenAI cautions that dots can make mistakes. A separate enterprise offering, specialist dots, is beginning pilots in procurement, invoice processing, email marketing, customer support and commercial contracting.
Plugins are being expanded as a shared way to connect services to ChatGPT, Codex and Dots. OpenAI announced plugin extensions with interactive panels and file viewers, a creator and submission flow, improved discovery, and support for Sites that let teams use an app with their own data and permissions. Support for the proposed MCP Events specification can let a plugin start an automation when an event occurs in a connected app. The company also announced an OpenAI Marketplace where eligible enterprise customers can spend part of their OpenAI commitment with 32 launch partners, including Figma, Adobe, Salesforce, ServiceNow, Harvey, CrowdStrike and Baseten.

The announcements put OpenAI between users and a wider range of software tasks. If a ChatGPT agent can select a plugin and complete work across connected services, companies may be discovered through the job their software performs, even when users do not seek out the company by name. That could shift competition toward plugin discovery, access permissions and task completion.
For developers, the expanded APIs and plugin tools offer routes to build software that agents can operate or invoke. The same shift raises practical questions about oversight: Dots can act in the background, while OpenAI’s own description acknowledges mistakes and keeps some sensitive actions under user control. The announced safeguards and staged access will shape how useful the agents are for work that carries financial or operational consequences.

From ChatGPT to Agent Platform
OpenAI framed the event as a move from ChatGPT as a chatbot toward an agent platform shared by people and software agents. It said ChatGPT reaches 1.2 billion weekly users. That figure is the company’s stated reach; the announcements do not independently establish how many of those users will use agents or plugins.
Alongside Dots and the plugin changes, OpenAI announced the Decisions API, which applies GPT-6 Luna to questions with a finite set of answers defined by the developer. It is in limited preview. The Agents API now supports computer use, allowing agents to operate software through its interface; OpenAI said it runs the Codex harness for developers. Sign in with ChatGPT will let users bring their existing plan to 16 launch partners. The model slate includes GPT-6.1 Sol, which OpenAI described as offering near-Astra intelligence at one-fifth of Astra’s token prices.
Availability and Performance Details
OpenAI has not provided full rollout dates for every announcement in the source material. Dots are available only to specified plans and eligible markets, and the enterprise beta requires an administrator to enable it. The Decisions API is in limited preview, while the broader release timing is not specified. Texting for Dots is described as coming, without a date.
Details also remain open on how GPT-6.1 Sol performs across independent evaluations, what workloads will count toward usage limits beyond the examples given, and how the announced safeguards will work in practice. OpenAI’s examples of agents completing tasks are company descriptions, not independent evidence of reliability.
Rollout and Developer Access
Developers and customers can expect staged access to the announced tools, including the limited-preview Decisions API and the Dots beta for eligible institutional plans. OpenAI says it plans a Microsoft Agent 365 integration for governance of specialist dots. The company has not given a date for that integration or for the planned texting feature.
The next indicators will be broader availability, developer documentation and evidence of how agents perform on real tasks. The announcements establish OpenAI’s direction; adoption, reliability and the practical reach of the new marketplace remain to be seen.
