TL;DR
At its September 29 DevDay, OpenAI announced more than 20 products and features aimed at making ChatGPT a platform for agents as well as a chatbot. The announcements include persistent Dots, expanded plugins, new agent APIs and GPT-6.1 Sol; availability varies, and some details remain limited or unspecified.
Dots are persistent agents powered by GPT-6 Astra, each with a cloud computer and browser. OpenAI says they can connect to more than 4,000 apps through plugins and work across ChatGPT on desktop, web and mobile, as well as Slack and Teams. Access to a user’s laptop requires permission. Voice calls are available; texting is planned.
OpenAI says Dots can keep projects moving and act on changing requirements. Its examples include monitoring customer feedback, updating analyses when new data arrives and preparing a sales proposal. One early tester’s Dot prepared an invoice and sent it only after the tester approved it. The first Dot is included in eligible plans, though tasks it starts in Codex or ChatGPT Work count toward usage limits. Access is rolling out to Pro and Business Premium users in eligible markets; Enterprise, Edu and Healthcare customers can use a beta when an administrator enables it.
OpenAI also expanded its plugin system, adding extensions inside ChatGPT, a creator and submission flow, improved discovery, hosted Sites for some organizations, and support for MCP Events that can trigger automations. The Agents API now supports computer use, with OpenAI running the Codex harness. A new Decisions API, powered by GPT-6 Luna, returns choices from a finite set defined by developers and is in limited preview. The company also announced Sign in with ChatGPT for 16 launch partners and GPT-6.1 Sol, which it described as offering near-Astra intelligence at one-fifth of Astra’s token prices.

The announcements put distribution and permissions at the center of OpenAI’s developer strategy. If users ask ChatGPT for an outcome and an agent selects a plugin to do the work, software companies may reach customers through the plugin directory before those customers know the company’s brand. That makes discovery, activation and task completion important measures for builders.
For organizations, agents that can use business software could automate recurring work, but they also need oversight. OpenAI says Dots have separate cloud computers, an Activity View, monitoring controls and rules to allow, require approval for or block actions. The company warns that agents can make mistakes; certain sensitive actions, such as changing a password, remain with the user.
The Decisions API targets a narrower use case: routing or classification where an application needs one answer from a developer-defined list. Computer use in the Agents API addresses a different problem, letting agents operate software through its interface. Both could reduce custom work for developers, though their practical performance and limits will depend on details not yet established in the source material.
From Chatbot to Agent Platform
OpenAI framed the event as a move from chatbot toward an agent platform. Its product announcements link ChatGPT, Codex and Dots through plugins that can package reusable skills, connections to external services using MCP servers, and optional user interfaces.
The company also announced an OpenAI Marketplace for eligible enterprise customers, allowing them to spend part of their OpenAI commitment with 32 launch partners, including Figma, Adobe, Salesforce, ServiceNow, Harvey, CrowdStrike and Baseten. Specialist Dots for businesses are beginning as pilots in procurement, invoice processing, email marketing, customer support and commercial contracting. OpenAI says it plans a Microsoft Agent 365 integration for governance.
Some features remain at early stages. The Decisions API is in limited preview, while Enterprise, Edu and Healthcare access to Dots is described as a beta that requires administrator enablement. The announcements establish what OpenAI says it is building and offering; they do not by themselves show how widely customers will adopt the tools.
Rollout and Performance Questions
The source material does not specify a broad release date for the Decisions API, beyond saying a wider release is planned. It also does not detail pricing for adding Dots, buying more speed or increasing monthly output, or identify all markets where the initial plans are eligible.
OpenAI’s descriptions of model capability, productivity examples and cost are company claims. Independent performance results, adoption figures and evidence about how reliably agents complete tasks are not provided. The material also does not explain the full safeguards or liability arrangements for errors made while agents use connected services.
Broader Access and Enterprise Pilots
OpenAI says it plans to expand Dots to Enterprise, Edu and Healthcare users through an administrator-enabled beta, while specialist Dots begin pilots across selected business functions. Developers can use the plugin creator and submission process to publish integrations, and eligible enterprise customers can access marketplace partners.
Further details to watch include the Decisions API’s broader release, availability and pricing across plans, and whether OpenAI’s planned Agent 365 integration gives organizations the controls they need. The company has not provided timing for those milestones in the supplied material.
