RotorQuant: 10-19x Faster Quantisation Alternative Using Clifford Algebra

Following Google's TurboQuant research, a community developer has invented RotorQuant, a novel quantisation approach leveraging Clifford algebra that achieves dramatic speedups over existing methods. By reducing parameter overhead by 44x while delivering 10-19x faster inference, RotorQuant represents a meaningful advancement in making large models practical for consumer hardware. The dual implementation in CUDA and Metal shaders ensures broad hardware compatibility.

Available on GitHub, RotorQuant demonstrates how novel mathematical approaches can unlock efficiency gains in local inference. For practitioners running models on limited hardware, this technique could enable deploying larger or faster models within existing memory and power budgets. The open-source availability means this optimization can be widely integrated into frameworks like llama.cpp and vLLM.
