RotorQuant is a KV cache compression method for LLM inference that replaces full d×d orthogonal rotations with block-diagonal Clifford rotor transforms, integrated as a drop-in quantization scheme in llama.cpp. It claims better perplexity and substantially faster decode/prefill than TurboQuant at the same compression ratio.
Use cases
- compress kv cache for long-context llm inference
- speed up llama.cpp decode and prefill
- reduce gpu memory for llm serving
- quantize attention k/v vectors at 3-bit
- compare against turboquant baselines
When to choose
- you serve LLMs via llama.cpp and need lower memory or higher throughput at low bit-widths
- you want KV cache quantization with minimal quality loss (PPL) and fast kernels on CUDA or Metal
When to avoid
- you need a permissively licensed dependency - the repo has no license
- you need a framework-agnostic solution outside llama.cpp/Triton
- you require independently verified benchmarks - results come from the authors' own paper
