# Quant Infos

- Requires llama.cpp [b4875](https://github.com/ggml-org/llama.cpp/releases/tag/b4875)
- LLM ONLY (No vision support)
- quants done with an importance matrix for improved quantization loss
- Quantized ggufs & imatrix from hf bf16, through bf16. `safetensors bf16 -> gguf bf16 -> quant` for *optimal* quant loss.
- Wide coverage of different gguf quant types from Q\_8\_0 down to IQ1\_S (WIP)
- Imatrix generated with [this](https://gist.github.com/bartowski1182/eb213dccb3571f863da82e99418f81e8) multi-purpose dataset by [bartowski](https://huggingface.co/bartowski).
