Anthropic's https://claude.ai/ grew a new feature today: an equivalent of OpenAI's ChatGPT Code Interpreter mode, where the chatbot can write and then execute code in order to help answer questions (e.g. to run calculations that are beyond a next-token-predicting LLM)
OpenAI use server-side Python for this, but Anthropic instead chose to use client-side JavaScript running in a Web Worker.
Here are my notes so far on the new feature: https://simonwillison.net/2024/Oct/24/claude-analysis-tool/

So you can literally ask - "freeze my webbowser".
