n separate repositories instead of variations (for example, stable-diffusion-v1-4 and stable-diffusion-v1-5). Otherwise, a variant is identical to the original checkpoint. They have exactly the same serialization format (like Safetensors), model structure, and weights that have identical tensor shapes. checkpoint type weight name argument for loading weights original diffusion_pytorch_model.bin  floating point diffusion_pytorch_model.fp16.bin v
