OpenAI announced more than 20 products and features at its September 29 DevDay, presenting ChatGPT as a platform where people and software agents can work across connected apps. The announcements include persistent Dots agents, upgraded plugins and new developer tools, while the company said ChatGPT reaches 1.2 billion weekly users.

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 connect to more than 4,000 apps through plugins, and can keep several projects moving over time. Users can reach Dots in ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls are available, while texting is described as forthcoming.

OpenAI said the first Dot is included for Pro and Business Premium subscribers in eligible markets. Enterprise, Edu and Healthcare customers can access a beta if an administrator enables it; the feature is off by default. Chatting with a Dot does not count toward usage limits, but tasks it starts in Codex or ChatGPT Work do. OpenAI says users can set rules that allow, require approval for or block actions, review background work, and pause or stop an agent. It also warns that Dots can make mistakes.

For developers, OpenAI expanded plugins, which can combine reusable skills, connections to external services through MCP servers, and optional user interfaces. New plugin extensions can appear in ChatGPT’s sidebar and provide interactive panels. OpenAI also announced a creator and submission flow, improved discovery, Sites for hosting plugins, and support for MCP Events that can trigger an automation when something happens in a connected app.

Agents Become a Route to Customers

The announcements point to a bid by OpenAI to make ChatGPT a place where software gets selected and work gets done, as well as a conversational product. If users ask an agent for an outcome and a plugin supplies the service, companies may reach customers through that interaction even when users do not seek out the company’s brand directly. That puts pressure on developers to make integrations useful, trusted and easy for agents to select.

For businesses, persistent agents could take on recurring tasks that currently require people to check multiple apps and update work as information changes. OpenAI’s examples include tracking customer feedback, revising a launch plan, updating a sales proposal and rerunning scientific analysis. Those are company examples, not evidence of typical performance. The safeguards and approval controls matter because an agent acting over time can affect business records and communications.

OpenAI also announced specialist Dots for enterprise pilots in procurement, invoice processing, email marketing, customer support and commercial contracting. The company says these agents will have their own identity, credentials and IT-provisioned hardware. It plans an integration with Microsoft Agent 365 for governance. If adopted, such tools could extend automation into more defined business responsibilities, though deployment and oversight arrangements will shape their practical use.

From ChatGPT to Agent Platform

OpenAI framed the event as a shift from ChatGPT as a chatbot toward a shared surface for people and agents. It presented the product’s reported 1.2 billion weekly users as the reach for that strategy. That figure is OpenAI’s claim in the supplied event material; no measurement method or time-series comparison was provided.

The plugin changes support that direction. Businesses can publish an integration once to a shared directory, while users choose which plugins to connect and approve access. OpenAI says eligible enterprise customers can also use an OpenAI Marketplace featuring 32 launch partners, including Figma, Adobe, Salesforce, ServiceNow, Harvey, CrowdStrike and Baseten. The company also introduced Sign in with ChatGPT for users to bring an existing plan to 16 launch partners, a setup that could support free core apps with paid upgrades.

The API announcements target different kinds of work. The Decisions API applies GPT-6 Luna to questions with a finite set of permitted answers, allowing applications to classify material, route requests or choose an agent action. It is in limited preview. The Agents API now supports computer use, letting agents operate software through its interface; OpenAI says it runs the Codex harness for developers. OpenAI also announced GPT-6.1 Sol, which it described as offering near-Astra intelligence at one-fifth of Astra’s token prices.

Availability and Agent Limits

Several details remain unsettled. The Decisions API is in limited preview, and the supplied material does not specify its broad release date, eligibility criteria or pricing. Dots availability depends on plan and market, with enterprise access requiring an administrator to enable the beta. OpenAI has not provided a general rollout schedule for every announced feature.

The announcements describe intended capabilities and company examples, but do not establish how reliably Dots will complete tasks across different apps or how much human review customers will need. The material also does not provide independent evidence for the model performance comparison or the weekly-user figure. The planned Microsoft Agent 365 integration and forthcoming Dot texting feature have no stated delivery dates.

Previews, Pilots and Rollouts

Developers and eligible customers can begin evaluating features as access becomes available: the Decisions API is in limited preview, and enterprise Dots are in beta for organizations whose administrators enable them. OpenAI says it is piloting specialist Dots across selected business functions and plans a Microsoft Agent 365 integration.

Further milestones include broader API availability, rollout of plugin tools and discovery changes, and the arrival of Dot texting. OpenAI has not provided dates for these steps in the supplied announcement material. For now, builders will need to check feature access and terms for their accounts while assessing whether agent-driven workflows fit their applications.
