Could you build this?
No Mathematically lossless 5-bit LLM compression requires novel mathematical research in information theory and weight tensor decomposition.
What it would actually take: A lossless compression scheme targeting neural network weights requires novel entropy coding algorithms, custom quantization matrix optimizations, and custom CUDA/Triton kernels for near-zero decompression overhead during inference. This is cutting-edge academic research in numerical analysis and systems ML that cannot be vibe coded.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
