 This repository is a fork of [llama.cpp](https://github.com/ggerganov/llama.cpp) with better CPU and hybrid GPU/CPU performance, new SOTA quantization types, first-class Bitnet support, better DeepSeek performance via MLA, FlashMLA, fused MoE operations and tensor overrides for hybrid GPU/CPU inference, row-interleaved quant packing, etc.
 
+>[!IMPORTANT]
+>Do not use quantized models from Unsloth that have `_XL` in their name. These are likely to not work with `ik_llama.cpp`.
