## Summary

Mistral AI says Mistral Large 4 wrote a quantum chemistry SCF solver from scratch from a short prompt, validated its output, and built a 3D visualization around it. The model also chose how to break the molecule and which orbitals to display without further input.

We asked Mistral Large 4 to show what happens when you break a molecule. ⚛️

With a short prompt, it wrote a quantum chemistry SCF solver from scratch, validated its output, and built a 3D view around it. 

Le Chonk also understand chemistry enough to independently choose how to break the molecule and what orbitals to show, without further input. 🧵
