Getting any performance improvement over vLLM is just a bonus although the RAM reductions are very nice. The main point is that we find deploying Python based projects to be a pain. I can't imagine how you know what files are unreachable in a dynamic language, but in any case that doesn't begin to solve issues like PyTorch requiring a C++ compiler at runtime to generate optimised CPU code. This isn't exactly embedded device friendly.

Having said that if you know of some magic bullet to fix the problems with the Python ecosystem (that vLLM and Pytorch are apparently unaware of) then I will be happy to try it because our CI is constantly blocked by Python related issues.
