ChatGPT app splits into Chat, Work, Codex — all on GPT-5.6
OpenAI has restructured its desktop ChatGPT app. The old desktop app has simply been renamed '' — it is not a new model. The new desktop app, called just 'ChatGPT,' merges three previously separate pieces: Chat, ChatGPT Work, and Codex.
Classic keeps getting model updates and security fixes and can still be used, but some new agent features are exclusive to the new app. The new app splits by role: Chat handles normal conversation, search, and question-answering; Work handles long-running like business documents, research, apps, and file workflows; Codex handles software development against code , files, terminals, and Git. ChatGPT Work runs on GPT-5.6, and Codex is also getting GPT-5.6-powered upgrades.
Work is rolling out first to Pro, Enterprise, and Edu users on web and mobile, then to Plus and Business over the following days. The new desktop app itself — with Chat, Work, and Codex all included — is available globally on Mac and Windows, even for Free users, though specific features and vary by plan. GPT-5.6 is not a single model but a family that includes Sol, Terra, and others.
