OpenAI DevDay 2026 releases Dots agent and GPT-6.1 Sol

OpenAI introduced features at Dev Day that turn ChatGPT into a place to discover, launch, and use software, directly challenging traditional app stores. ChatGPT will recommend apps in conversations and support using them inside ChatGPT. Its extension architecture now supports interactive components that developers can build. Sign in with ChatGPT lets users bring their AI credits into third-party apps, with 16 launch partners.

GPT-6.1 Sol is now generally available on Amazon Bedrock, offering stronger reasoning for agentic coding, computer use, and professional workloads. OpenAI says it matches GPT-6 Astra on DeepSWE v1.1 at about one-fifth the cost per task, and scores 6.4 percentage points above GPT-6 Sol’s best result.

In a September 29 post, Simon Willison discussed GPT-6.1 Sol’s near-Astra intelligence at about one-fifth the price. The original post did not disclose specific model parameters, benchmark scores, or pricing figures.

OpenAI shared new usage figures at DevDay: ChatGPT has more than 1.2 billion weekly active users; ChatGPT Work and Codex have over 35 million weekly active users; and 2.5 million businesses use OpenAI products.

At DevDay, OpenAI launched personal agent Dots, powered by GPT-6 Astra and designed to run users’ goals continuously in the background without relying on specific hardware or an interface. Dots became available that day in ChatGPT to Pro and Business Premium users. It can be started from Codex or ChatGPT and supports interaction through Slack, Teams, and other platforms; SMS support is coming soon.

In its DevDay keynote, OpenAI launched Dots, an always-on AI assistant powered by GPT-6 Astra. It can use its own cloud computer to access a browser and more than 4,000 supported apps, and can be controlled through a text-like interface or voice calls.

At DevDay 2026, OpenAI launched always-on agent Dots, which can autonomously handle tasks such as fixing bugs reported in Slack and sending forgotten invoices. It also introduced the cheaper GPT-6.1 Sol; its higher-end GPT-6.1 Astra was held back over safety concerns.

At DevDay 2026 in San Francisco, OpenAI announced Codex and API expansions: Codex adds reusable cloud development environments and Codex Security Cloud repository vulnerability scanning; the ChatGPT desktop app gains a code review view; and Codex CLI has been redesigned with voice-based task initiation and control.

OpenAI has released GPT-6.1 Sol, saying it approaches the flagship GPT-6.1 Astra—which was delayed over safety concerns—in agentic coding, computer use, and office tasks, at about one-fifth the cost.

OpenAI held its annual DevDay in San Francisco on September 29, unveiling Dots, an AI agent product positioned against Meta's recently launched Muse. Initially, Dots is available only to paying ChatGPT Pro, Business Premium, and Enterprise subscribers.

Simon Willison live-blogged the OpenAI DevDay 2026 keynote at Fort Mason in San Francisco. OpenAI unveiled Dots, a personal agent powered by Astra, ChatGPT Space, GPT-6.1 Sol, and an Ultrafast mode reaching up to 300 tokens per second.

OpenAI's DevDay 2026 recap covers more than 20 launches spanning GPT-6 Astra, ChatGPT, Codex, the API, safety, and new developer tools.

OpenAI has released dots, a proactive assistant that can keep work moving on complex projects and everyday tasks. The company says dots lets users retain control as tasks progress.
