Can Claude Sonnet 4 write x86 assembly? I ran an experiment today and got Claude plus Claude Code to build, run and debug a pleasing Mandelbrot fractal in assembly, compiled via Docker on my Mac Full details, including prompts and Claude Code transcript, here: simonwillison.net/2025/Jul/2/m...

A family member was having trouble getting Claude to write assembly inlined in C, took more than a few retries. Was this a one shot?

I shared my exact prompt sequence - not quite one shot but close The key is having a tool like Claude Code that can run the compiler in a loop and fix its own errors
