llama.cpp PR #30517 Delivers Big CUDA Speedup for Low-Bit Q2_K/Q3_K Quantization
jacek2023 · reddit · 2026-10-17
llama.cpp merged a CUDA optimization PR (#30517) by am17an that speeds up MMVQ kernels for low-bit quantization types.
- Impact: a big speedup, but only for specific quantization formats such as Q2K and Q3K.
- Relevance: users running local LLMs at aggressive low-bit quants get directly faster inference on these popular formats.
The PR carries +125/-59 lines of changes with 9 comments and 2 reviews so far.
