TL;DR
At its Sept. 29 DevDay, OpenAI announced more than 20 products and features aimed at making ChatGPT a platform for people and software agents. The major announcements include persistent Dots, expanded plugins, APIs for decisions and computer use, and Sign in with ChatGPT; availability varies, and several details remain limited or unannounced.
OpenAI described Dots as persistent agents powered by GPT-6 Astra, each with its own cloud computer and browser. The company says a Dot can work on ongoing projects, connect to more than 4,000 apps through plugins and be reached through ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls are available, while texting is described as forthcoming. The first Dot is included with eligible Pro and Business Premium plans in supported markets; Enterprise, Edu and Healthcare customers can access a beta if an administrator enables it.
OpenAI also expanded its plugin system, adding extensions inside ChatGPT, a creator and submission flow, improved discovery, Sites for sharing plugins within organizations and support for MCP Events that can trigger automations. The company said eligible enterprise customers can use OpenAI Marketplace to spend part of their OpenAI commitment with 32 launch partners, including Figma, Adobe, Salesforce and ServiceNow.
For developers, the Decisions API applies GPT-6 Luna to choices drawn from a finite list set by the developer; it is in limited preview. The Agents API now supports computer use, with OpenAI operating the Codex harness. Sign in with ChatGPT lets users use an existing ChatGPT plan with 16 launch partners. OpenAI also announced GPT-6.1 Sol, which it described as offering near-Astra intelligence at one-fifth of Astra’s token prices.

The announcements put software discovery and task completion at the center of OpenAI’s developer strategy. If users ask ChatGPT to complete a task and a plugin connects the service that performs it, businesses may reach customers through an agent interaction rather than a direct visit to their own app. That could change how companies attract users and how developers assess whether integrations are being selected and completing work.
Dots extend that approach to work that continues over time. OpenAI says agents can monitor updates and act across connected services, while the new computer-use support gives agents another way to operate existing software. These capabilities could reduce manual handoffs, but also make permissions, oversight and reliable execution central concerns for organizations adopting them.

From ChatGPT to Connected Agents
OpenAI framed ChatGPT as a shared interface for people and agents, citing 1.2 billion weekly users. That figure is the company’s stated reach; the announcement material does not provide a measurement period or methodology beyond describing it as weekly users.
The DevDay package links consumer-facing agents with developer infrastructure. Plugins provide connections and interfaces, while APIs let developers hand off specific decisions or software interactions. OpenAI also described specialist Dots for enterprises, with distinct identities, credentials and IT-provisioned hardware. Initial pilots are planned in procurement, invoice processing, email marketing, customer support and commercial contracting, alongside a planned Microsoft Agent 365 integration for governance.
Access, Controls and Performance Details
Availability differs by product and customer type: Dots are initially limited by plan and market, enterprise and education access requires an enabled beta, and the Decisions API is in limited preview. The source material does not specify a broad release date for that API, beyond saying one is promised, and gives no complete rollout schedule for the announcements.
OpenAI cautions that Dots can make mistakes. It describes controls including Custom Rules, approval requirements, an Activity View and options to pause or stop an agent; sensitive actions such as changing a password remain with the user. The announcement does not establish how these safeguards will perform across all integrations, or provide independent evidence for GPT-6.1 Sol’s stated price and capability comparison.
Rollout Moves Into Previews and Pilots
OpenAI’s immediate next steps are to make Dots available to eligible subscribers and begin enterprise pilots, while developers can explore the limited-preview Decisions API and the expanded plugin submission process. The company has also described a planned Microsoft Agent 365 integration for enterprise governance. Broader release dates and further details on access, pricing for additional Dots and API availability were not specified in the source material.
