Quantization precision recommendations: prioritize BF16 for production environments, INT4 is acceptable for test environments, and the minimum threshold should not go below INT4, as lower precision results in greater loss of model capability and output quality.

UnverifiedMixed-precision quantization applies aggressive low precision such as INT4 to backbone networks that have large parameter counts but are not precision-sensitive, while retaining INT8 or FP16 for precision-sensitive components such as text encoders and QKV projections.76% similarUnverifiedGradient checkpointing and mixed-precision training (FP16/BF16) are common memory-reduction measures.70% similarUnverifiedThe core principle of quantization is to convert model parameters from high-precision floating-point representations (such as FP32's 32-bit floating point) to low-precision representations (such as INT8's 8-bit integer or INT4's 4-bit integer).69% similarUnverifiedThe tester's initial configuration was CFG 1, Steps 40, resolution 2MP, aspect ratio 4:3, sampler Euler, scheduler Simple, with the model and text encoder using int8 quantization and the VAE at bf16 precision.69% similarUnverified在Transformer架构中，每个参数在BF16精度下占2字节，INT8精度下占1字节，INT4精度下占0.5字节67% similar
