TL;DR
At its Sept. 29 DevDay, OpenAI announced more than 20 products and features, with persistent Dots, expanded plugins and new agent APIs among the main developments. Several offerings are available only to certain plans or in limited preview, and the source material does not give complete details on the model lineup or broader rollout dates.
OpenAI announced more than 20 products and features at its DevDay on Sept. 29, presenting ChatGPT as a platform used by people and software agents. The announcements include persistent Dots, expanded plugins and new APIs that could let businesses delegate routine work to agents, though access and availability vary by product.
The most prominent consumer announcement is Dots, persistent agents powered by GPT-6 Astra. Each Dot has its own cloud computer and browser, can connect to more than 4,000 apps through plugins, and is intended to keep working on goals over time. OpenAI says users can reach Dots through ChatGPT on desktop, web and mobile, as well as Slack and Teams. Voice calls are available, with texting described as coming later.
Access is limited by plan and market. The first Dot is included for Pro and Business Premium users in eligible markets. Enterprise, Edu and Healthcare customers can use a beta if an administrator enables it; the feature is off by default. OpenAI says chatting with a Dot does not count toward usage limits, while tasks it starts in Codex or ChatGPT Work do. Users may later add Dots or pay for more speed and monthly output.
OpenAI also expanded its plugin system, adding extensions that can appear in ChatGPT’s sidebar and provide interactive panels or file viewers. A revised creator and submission process, improved discovery, and support for MCP Events—which can trigger an automation when something happens in a connected app—were among the changes. Sites can host plugins for teams using Business, Enterprise, Healthcare or Edu plans. An OpenAI Marketplace lets eligible enterprise customers direct part of their OpenAI commitment to 32 launch partners.
Two API announcements target specific kinds of work. The Decisions API applies GPT-6 Luna to choices drawn from a finite set of answers defined by the developer; it is in limited preview. The Agents API adds computer use, allowing agents to operate software through its interface, with OpenAI running the Codex harness. Separately, Sign in with ChatGPT lets users bring an existing plan to 16 launch partners, a setup that could support free core apps with paid upgrades.

The announcements could change how software companies reach customers. OpenAI’s presentation describes a model in which a user asks ChatGPT for an outcome, and an agent selects a plugin to do the work. In that arrangement, the agent may choose a service before the user knows its brand. Developers could need to pay close attention to whether their plugins are discovered, activated and able to complete tasks.
For businesses, Dots and specialist agents could take on recurring work such as processing invoices, handling customer support or revising proposals. OpenAI says each consumer Dot operates on its own cloud computer, and gives users controls to allow, approve or block actions. Those features address questions about oversight, but do not establish how reliably agents will perform across real-world tasks. The company warns that Dots can make mistakes.
The commercial reach is also uncertain. OpenAI says ChatGPT has 1.2 billion weekly users, giving the platform a large potential audience for plugins and partner apps. The announcement material does not specify how that figure was measured or how many users will adopt agents, so it does not show the likely customer base for any individual developer.
The DevDay Platform Push
OpenAI’s Sept. 29 event brought together consumer agents, enterprise tools, developer APIs and partnerships under a broader ChatGPT platform pitch. The company says plugins can combine reusable skills, connections to external services through MCP servers and optional user interfaces, then be published to a shared directory. Dots use that ecosystem to connect with outside apps.
For enterprise customers, OpenAI described specialist Dots with their own identities, credentials and IT-provisioned hardware. Initial pilots cover procurement, invoice processing, email marketing, customer support and commercial contracting. The company also plans an integration with Microsoft Agent 365 for governance. The source material does not give dates for those pilots or the planned integration.
OpenAI also named GPT-6.1 Sol, which it described as offering near-Astra intelligence at one-fifth of Astra’s token prices. The supplied source refers to additional model announcements, including Ultrafast and Pro 500, but ends before explaining them. Their capabilities, pricing and availability cannot be assessed from the available details.
Availability and Reliability Questions
The announcements leave open when many features will reach wider availability. Dots are limited to specified plans and eligible markets, while the Decisions API is in limited preview. The source does not provide general-release dates for the expanded plugin tools, computer use or Sign in with ChatGPT.
OpenAI has not supplied performance figures in the material for how often Dots complete tasks successfully, how they handle mistakes, or what added Dots and higher output will cost. The descriptions of invoice processing, customer feedback and research work are examples from OpenAI, not independent evaluations. The precise terms and safeguards for the 16 sign-in partners are also not provided.
The model slate is only partly described in the supplied material. It gives a price comparison for GPT-6.1 Sol but no underlying benchmark, token-price figures or release details, and it names other models without explaining them. Those gaps make it difficult to compare the models or judge the scope of the pricing claim.
Rollouts and Developer Adoption
Near-term developments include access to Dots for eligible Pro and Business Premium users, and beta access for enterprise, education and healthcare organizations whose administrators enable it. Developers can watch for broader access to the Decisions API and computer-use support, but the source material gives no target dates for general release.
OpenAI says it is beginning specialist-agent pilots in several business functions and plans a Microsoft Agent 365 integration. Plugin creators will also have a new submission flow and discovery features to work with. How quickly partners adopt these tools—and whether users choose agent-selected services—will become clearer as rollouts progress.
