Fun fact, I needed JPEG XL support for my C++ pipeline and I didn't feel like including any official libraries. Roughly $500 tokens later I had a fully working optimized JPEG XL spec compliant en/de/coder that outperformed the official codepaths (both cpp and rust) by 70% (lower runtime). Took literally 5 hours to build out. Can someone tell me what Google is doing?

So do you think your implementation is better? Or there are finer parts of the spec it’s missing?

Your llm has JPEG xl programs in the training data. You copied from GitHub.
