OpenAI DevDay 2026: Unveiling Long-Running Agent Dot and GPT-6.1

Overview

At the recently held OpenAI DevDay 2026 conference, OpenAI unveiled its most extensive lineup of technological updates to date, encompassing comprehensive upgrades across ChatGPT, Codex, and foundational models. The core focus of this announcement was the introduction of Dot, an agent capable of long-term execution, alongside the significantly enhanced GPT-6.1 Sol model, marking a new stage in AI collaboration.

OpenAI emphasized that the ultimate goal of AI is to unleash human creativity, allowing people more time to focus on important matters. To this end, the company has formally opened ChatGPT as a shared platform for human-agent collaboration, enabling developers to build native experiences directly to its total user base of 1.2 billion.

Core Products and Technological Breakthroughs

This conference introduced several key products aimed at reshaping human-machine collaboration:

• Dot Agent: As OpenAI's latest long-term agent, Dot is powered by the most intelligent and best-aligned GPT-6 Astra model. It possesses an independent cloud computer capable of carrying out responsibilities continuously around the clock. Users simply need to set goals and define permissions, after which Dot can autonomously undertake tasks. In the future, multiple Dots will form teams to collaborate, available to Pro, Business Premium, and Enterprise plan users.
• GPT-6.1 Sol: This is a major upgrade to GPT-6 Sol, demonstrating exceptional performance in agent programming, computer usage, and professional work scenarios. Its ability to handle high-difficulty tasks has approached that of GPT-6 Astra, yet its token pricing is only one-quarter of the latter, significantly reducing costs for developers running complex workflows.
• Astra Ultrafast: A premium speed tier designed specifically for low-latency needs, offering speeds up to 6 times that of standard Astra in the API, and up to 8 times faster in Codex and "ChatGPT for Work," helping to maintain developer flow and enhance user experience.

Ecosystem Opening and Developer Tools

OpenAI further upheld its commitment to an open ecosystem by empowering developers and enterprise management through various tools:

1. Codex and API Upgrades: The newly launched Codex Cloud supports on-demand cross-device operation, providing reusable development environments. The Codex CLI now adds voice dialogue, an /agents view, and built-in support for working trees, significantly boosting daily development efficiency.
2. Plugin System Overhaul: The ChatGPT plugin extension feature allows developers to set up dedicated entry points in the sidebar to build interactive panels. It also supports the MCP Events specification, enabling plugins to automatically trigger automation workflows when application events occur.
3. Enterprise Collaboration: The new ChatGPT Workspace supports team-based collaborative editing of dynamic pages, presentations, and spreadsheets. Integrations with Slack and Microsoft Teams allow discussions to be initiated via @ChatGPT mentions, while meeting plugins can automatically generate meeting notes and sync them to the workspace.
4. Security and Privacy: Privacy Intelligence integrates zero-data retention and a privacy inference preview, ensuring data security for enterprises when using cutting-edge models. Additionally, Codex Security Cloud introduces Defense Factory's continuous defense methods and the Daybreak Blue model, supporting automated code scanning and vulnerability remediation.

OpenAI also simultaneously launched a new Pro tier at $500 per month and introduced the OpenAI Software Marketplace, with initial partners including industry giants such as Adobe, Figma, and Salesforce, further enriching the enterprise AI application ecosystem.
