Gemma 4 31B model sees 10% speed boost with Q4_K quantization

A user on Reddit's r/LocalLLaMA subreddit shared their experience quantizing the Gemma 4 31B model. By converting the f16 MTP draft model to Q4_K quantization, they observed an approximate 10% increase in decoding speed, moving from 65 TPs to 72 TPs. The user experimented with different quantization methods, noting that Q2_K yielded worse results. AI
