If you’re using docker anyway, and “fast” pure GPU models, you might try a vllm container while you’re at it.
It should be much faster than even llama.cpp, albeit at the cost of context length, and it supports some exotic 4-bit quantization like SPQA.
Same with TabbyAPI. It’s quantization is SOTA, though it does not support CPU offloading, and it’s speed is somewhere between vllm and llama.cpp.
