Q4_K_M recommended for local LLM quantization, balancing quality and VRAM

The article recommends Q4_K_M quantization as the best balance of quality and VRAM efficiency for most local LLM users, preserving 93-96% of FP16 quality. For users with more VRAM, Q5_K_M offers a noticeable improvement in complex reasoning and creative tasks. Lower quantization levels like Q3_K_M are presented as compromises for tight VRAM, while Q6_K and Q8_0 offer diminishing returns, and Q2_K and below are considered last resorts due to significant quality degradation.
