Saw this cool thread and was inspired to add eigh and svd to jax-js, via Jacobi iteration!
It runs in your browser, on GPU compute shaders or Wasm backends. It ain't crazy fast like these CUDA kernels, but it finally works: https://jax-js.com/pca
Happy July 4 :D

GPT 5.6 Sol autoresearch on the GPUMODE eigh problem is... different
Compared to Opus:
- Progressing much slower - Many more failures (trying harder things) - Explores fewer ideas (doesn't give up) - 5x less lines of code - Simpler C++ (reminds me of my own) - Fewer comments
