[Official FAQ] Corrections and follow-up questions welcome.

These are different ecosystems. GGUF pairs naturally with llama.cpp/Ollama-style workflows. GPTQ/AWQ appear more in Transformers/vLLM/TGW stacks on NVIDIA.

Rule of thumb:

  • Simple cross-platform / CPU / Apple: start with GGUF.
  • High-throughput multi-user NVIDIA serving: check vLLM’s supported formats (AWQ/GPTQ/FP8/etc.).
  • Equal “4-bit” labels are not interchangeable across loaders.

Quality is empirical—compare on your prompts.
