OpenAI DevDay 2026 Announcements: Dots Agents, ChatGPT Space and GPT-6.1 Sol
OpenAI just wrapped its biggest product event of the year. At DevDay 2026 in San Francisco on Tuesday, September 29, the company unveiled more than 20 new announcements — headlined by Dots, its new always-on AI agents, a shared ChatGPT workspace called Space, and a new GPT-6.1 Sol model. The OpenAI DevDay 2026 announcements signal the company’s most aggressive push yet beyond the chatbot window: AI that keeps working while you are not looking.
Meet Dots: OpenAI’s always-on AI agents
The flagship launch of the keynote is Dots — personal AI agents OpenAI describes as “remarkably capable, always-on agents built to handle everything.” Unlike ChatGPT or Codex, which wait for a prompt, Dots are designed to pursue user-defined goals continuously in the background with minimal oversight. TechCrunch reports that Dots run on GPT-6 Astra, OpenAI’s most advanced model, and each dot gets its own cloud computer and browser.
According to OpenAI’s announcement, users start with a primary dot they can name and personalize, with “teams of Dots” envisioned over time. Dots connect through the company’s plugin ecosystem to more than 4,000 applications and can be reached through ChatGPT, Slack and Microsoft Teams, with text-message support coming soon. OpenAI is also piloting specialist Dots with their own organizational identities, credentials and system access for specific business responsibilities — from procurement and invoice processing to customer support. VentureBeat notes the company is working with Microsoft to integrate these agents into Microsoft’s Agent 365 security controls.
ChatGPT Space, Pages and slides: a direct run at the office suite
Paired with Dots is ChatGPT Space, a shared workspace inside ChatGPT where coworkers can collaborate with the chatbot, Codex and their Dots. “Your pages and files all live together in Space, like they would in a drive,” CEO Sam Altman said during the keynote, “but spaces feel alive.” Space replaces ChatGPT’s existing Library for Pro, Business and Enterprise users and acts as a home for Pages, files, presentations and spreadsheets, as VentureBeat reports.
OpenAI also introduced Pages, a new document type it calls “built for human and agent collaboration” — its answer to Google Docs and Microsoft Word — where users can write, research, generate charts, create images or visualize information, and which can stay synchronized with connected tools. And there is collaborative slides, OpenAI’s answer to PowerPoint: slides created simply by talking in ChatGPT, with multiple workers and agents able to co-edit and comment. As TechCrunch puts it, OpenAI is increasingly going after Microsoft’s bread and butter — workplace software — even as Microsoft tries to become more like OpenAI.
For developers: GPT-6.1 Sol, the Agents API and Codex in the cloud
Developers got a major upgrade too. GPT-6.1 Sol is a major upgrade to GPT-6 Sol aimed at agentic coding, computer use and professional work, offering near-Astra intelligence at a fifth of the standard input and output token prices, according to OpenAI — giving developers more room to run complex workflows within the same budget. It is available now to API, Plus, Pro, Business, Enterprise and Edu users, Thurrott reports.
OpenAI also launched the Agents API, a managed agent runtime with environments, sessions, tools, MCP support, context management and multi-agent capabilities. And Codex moved into the cloud: developers can now access Codex from any device with reusable development environments and team settings, plus new CLI controls and an UltraFast tier OpenAI says generates up to 300 tokens per second in Codex.
Why this matters: the battle for the personal agent
Dots is not arriving in an empty market. It is OpenAI’s direct answer to Meta’s Muse, the personal AI agent launched on September 8 that has been breaking adoption records — TechCrunch cited Sensor Tower data estimating more than 3.4 million downloads by September 24, topping US app-store charts. As Barron’s noted, Meta’s stock rose after the Dots announcement while Salesforce and ServiceNow shares slipped, as investors weighed how always-on agents might disrupt enterprise software.
The deeper shift, as VentureBeat frames it, is from AI that answers questions to AI that owns workflows: employees delegate objectives and standards, and the agent monitors systems, manipulates software and responds as circumstances change. That turns the competitive question from whose model gives the best answer into which agent a person or business trusts with continuous access to the machinery of their work.
Who gets what, and when
Dots are rolling out now inside ChatGPT for Pro and Business Premium users in eligible markets, launchable from Codex or ChatGPT, with wider onboarding to follow. ChatGPT Space is available to Pro, Business and Enterprise tiers. GPT-6.1 Sol and the Agents API are available to developers and across paid plans starting today. OpenAI says Dots’ background “proactive research” tools are read-only by default, with Custom Rules, an Activity View and an auto-review system governing consequential actions — and sensitive operations such as password changes remaining human-only.
What to watch next
The announcements are only hours old, and the real test begins now: how Dots behave in real workplaces, how quickly developers adopt the Agents API, and whether the office-suite push turns ChatGPT from a tool into a platform. With persistent personal agents becoming the next major interface battle in AI, DevDay 2026 may be remembered as the day OpenAI officially entered the fight.
