Simon Willison provides a deep dive into OpenAI's ChatGPT Work, distinguishing between the cloud version and the local version (formerly Codex). Work offers advanced features not found in Chat:
- Model Selection: GPT-5.6 (Sol/Luna/Terra) with various reasoning levels.
- Code Execution & Internet Access: Sandbox can access the internet, install packages, and clone GitHub repos.
- Headless Chrome: Launch browsers to load pages, fill forms, and execute JS.
- Persistent Filesystem: Shared storage across sessions.
- ChatGPT Sites: Deploy static sites via Cloudflare Workers.
- Sub-agents: Parallel collaboration of multiple Sol/Luna/Terra agents.
Willison also highlights security concerns regarding the "lethal trifecta" of combining private data with external access.
