不同尺寸模型文件区别

sd3_medium.safetensors 4.34GB, includes the MMDiT and VAE weights but does not include any text encoders, you need to download T5XXL text encoder yourself.

sd3_medium_incl_clips.safetensors 5.97GB, includes all necessary weights except for the T5XXL text encoder. It requires minimal resources, but the model’s performance will differ without the T5XXL text encoder.

sd3_medium_incl_clips_t5xxlfp8.safetensors 10.9GB, contains all necessary weights, including fp8 version of the T5XXL text encoder, offering a balance between quality and resource requirements.

sd3_medium_incl_clips_t5xxlfp16.safetensors 15.8GB, contains all necessary weights, including fp16 version of the T5XXL text encoder.

T5XXL is a new text encoder from Google, it has emerged as a powerful technique in natural language processing (NLP).
