VerifiedINT8 quantization results in almost imperceptible precision loss, and INT4 quantization also maintains good performance on most coding tasks.76% similarUnverifiedWhether the quality degradation of 1-bit quantization is acceptable in high-demand scenarios such as complex reasoning, long-context processing, and code generation still requires real-world validation75% similarUnverifiedIt is widely recognized in the industry that quantization below 2-bit leads to significant capability degradation on high-precision tasks such as complex multi-step reasoning and mathematical computation.71% similarUnverifiedPost-training quantization solutions such as GPTQ and AWQ can control performance loss to within 1–2% at INT4 precision70% similarVerified4-bit quantization techniques (such as GPTQ, AWQ, and the GGUF format) can reduce model VRAM requirements to 1/4 of the original, but come with a certain degree of accuracy loss69% similar
