Verified4-bit quantization reduces model size to 1/8 of the original at the cost of approximately 1–3% accuracy loss.78% similarUnverifiedint8量化将参数从16位压缩至8位，理论上减少约50%显存占用；int4将显存占用降低至原始的25%左右74% similarUnverifiedThe lower the quantization bit depth, the more likely the model is to show degraded performance on detailed reasoning, but for most tasks at quantization levels above 4-bit, the experiential difference is not obvious to ordinary users.73% similarUnverified通过INT8或INT4量化，可将模型显存占用降低50%至75%71% similar
