Clarifying the Differences Between ChatGPT Work Cloud and Local Versions

Developer Simon Willison analyzed OpenAI's "ChatGPT Work" product, clarifying that it consists of two distinct versions: a cloud-based version ("Work Cloud") and a local desktop application version ("Work Local"). The cloud version offers advanced capabilities like persistent filesystems, headless Chrome, and specific model selections including GPT-5.6 Sol, Luna, and Terra. As OpenAI expands its product ecosystem, understanding the distinction between standard chat interfaces and task-oriented "Work" environments helps paid subscribers leverage specialized features like sub-agents and code execution. This distinction highlights OpenAI's shift toward agentic workflows and developer-focused tools for mainstream business users. ChatGPT Work is restricted to paid subscribers ($20/month and above) and introduces model options like GPT-5.6 Sol, Luna, and Terra with varying reasoning levels. Additionally, "Work Local" is a rebranded version of the OpenAI Codex desktop application, allowing direct file access and program execution on the user's computer.
