OpenAI today announced the full integration of Codex into ChatGPT, giving birth to ChatGPT Work, an AI agent capable of executing complex tasks across web, mobile, and desktop. The announcement coincides with the release of new GPT-5.6 models, named Sol, Terra, and Luna, which power this new platform.
ChatGPT Work Unifies Codex and ChatGPT into One Assistant
With this update, OpenAI has merged the Codex app with ChatGPT, creating a unified experience. ChatGPT Work can access local files and apps, use a built-in browser to navigate websites and online tools, and leverage plugins to connect to external systems. An exciting new feature is Sites, still in beta, which allows users to create interactive websites and web apps for reports and live dashboards. Tasks can be started and managed from any device, including smartphones. The agent executes multi-step tasks autonomously, using scheduling to work in the background across multiple apps.
