How does Exllama rank among these? Heard good things about it.
- helloericsf 2y agoSeems interesting! https://github.com/turboderp/exllama https://github.com/turboderp/exllama "A more memory-efficient rewrite of the HF transformers implementation of Llama for use with quantized weights."
- helloericsf 2y ago4-bit quantization tends to come at the cost of output quality losses. https://github.com/ggerganov/llama.cpp/issues/9 https://github.com/ggerganov/llama.cpp/issues/9
- ssheng 2y agoQuality loss with quantization is expected. It seems like with GPTQ the loss is within acceptable range based on the perplexity score shown.
