ChatGPT Work adds open-internet code execution and a headless Chrome on $20 plans

Simon Willison pins down what ChatGPT Work actually adds over Chat: a code sandbox whose internet access defaults to open, a full headless Chrome that fills forms and runs JavaScript, and a /workspace filesystem that persists across sessions. Cloning a repo, installing its dependencies, and driving live sites with them is now available to any $20/month subscriber — well past Claude's container, which allowlists PyPI, NPM, and GitHub. Willison flags the lethal-trifecta risk and faults OpenAI for withholding the system prompts and tool descriptions that would make that risk assessable.
