Understanding ChatGPT Work
Simon Willison meticulously dissects OpenAI's "ChatGPT Work," a product he deems both confusing and powerful. The article clarifies its key differentiating features, including internet-enabled code execution, persistent filesystems, and website deployment, which are crucial for advanced AI agent use. This deep dive is essential for paid subscribers navigating the poorly documented nuances of OpenAI's latest offering.
The Lowdown
Simon Willison's article aims to demystify OpenAI's "ChatGPT Work," which he labels as "extraordinarily confusing and very powerful." He distinguishes between "Work Cloud" (web/mobile) and "Work Local" (desktop app, formerly Codex), focusing primarily on the former to provide clarity on its unique capabilities and how it differs from regular ChatGPT Chat.
- Exclusivity and Models: ChatGPT Work, in both iterations, is accessible only to $20/month and higher subscribers. It offers distinct model selection options (GPT-5.6 Sol, Luna, Terra with varied reasoning levels) not found in Chat, and billing may differ from Chat sessions.
- Internet-Enabled Code Execution: A standout feature, Work's code execution environment can now access the internet, allowing installation of software, interaction with websites, and APIs. This is a significant leap beyond ChatGPT Chat's sandboxed limitations.
- Headless Chrome Browser: Work includes a full headless Chrome instance capable of loading websites, filling forms, taking screenshots, and executing JavaScript against the DOM. It also securely handles credentials for sign-ins.
- Persistent Filesystem: Unlike Chat's ephemeral storage, Work provides a persistent, shared filesystem, allowing users to access files created in previous sessions across multiple Work sessions.
- ChatGPT Sites: A novel feature enabling Work to build and deploy entire websites using Cloudflare Workers, supporting HTML, JavaScript, and server-side functionalities, including stateful features.
- Sub-Agents and Automations: Work supports the use of sub-agents (Sol, Luna, Terra) for complex, multi-agent projects and offers scheduled prompt automations for recurring tasks, which can be combined with other Work-exclusive features like updating ChatGPT Sites.
Willison raises critical questions about the safety of such a system, citing his "lethal trifecta model" that warns against combining private data access, untrusted content, and information exfiltration. He ultimately critiques OpenAI for its opaque documentation, suggesting that transparent system prompts and tool descriptions would greatly reduce user confusion.
The Gossip
Clarifying the Confused Codex
Commenters generally appreciate the article for demystifying the convoluted distinctions between ChatGPT Work and Chat, and particularly for highlighting the power of Work Local (formerly Codex). Many express frustration with OpenAI's unclear product segmentation and budget allocation, noting that Work's billing against the Codex allowance makes it a non-starter for some users who prioritize their existing Codex budget. There's a sentiment that while powerful, the product's structure is unnecessarily complex.

Pricing Pains and Plan Particulars
Discussion around subscription tiers reveals that 'Extra High' and 'Pro' levels are available through ChatGPT for Teams ($25/seat, min 2 seats), not exclusively the $100+ tier, clarifying a point in the article. However, concerns are raised that these Team benefits might soon be restricted to even higher-priced 'Premium Seats,' signaling potential future pricing adjustments.
