Qwen3.5-4B GGUF Quants Compared: KLD Quality Loss vs. Inference Speed on Intel Lunar Lake If you’re running local LLMs on a Lunar Lake laptop, every quantization decision is a tradeoff. Pick too aggressive a quant and your Qwen3.5-4B outputs turn to mush. Pick too conservative a quant and you’re watching tokens trickle in at a speed that kills any productivity gain. This guide maps every major Qwen3.5-4B GGUF quant against its Kullback-Leibler Divergence (KLD) quality score and real-world tokens-per-second on Intel’s Core Ultra 200V (Lunar Lake) silicon, so you can make the call yourself. ...
