Recommended quantization gradient choices: Q8 is nearly lossless but has the largest footprint, Q6/Q5 are the sweet spot between quality and size, Q4_K_M is the default download version for most users, and the Q2/IQ series is suitable for use when the model barely fits.

UnverifiedQ8_0 is 8-bit block quantization with high precision but limited compression; Q4_K_M balances size and quality through mixed precision at the 4-bit level and is one of the commonly used default tiers for local deployment.78% similarUnverifiedQ6_K 使用 6-bit 量化并结合 K-quants 分组技术，相比 Q4 量化损失更小，相比 Q8 量化体积更小78% similarUnverified7B–9B parameter models typically occupy 5–7 GB of VRAM after Q4 or Q5 quantization.74% similarUnverifiedDifferent quantization types (such as Q4_K_M and Q8_0) each have trade-offs in size, speed and quality.74% similarUnverifiedQ5 quantization is considered by the community to be the sweet spot between quality and size, with the model size being approximately 30–35% of the original FP16, and performance loss typically within only 1–3%.73% similar
