fp8mixed.safetensors - Are there any code of how to convert a Diffusion model into Mixed FP8 which is better than Scaled FP8 right?

Hello. With FLUX first time we see Mixed FP8

As far as I understand it is better quality than even Scaled FP8

Are there any code, script of how this model was generated from BF16 version?

Converting Diffusion models into FP8 Scaled is being really helpful and it exists like Tensor Wide but this Mixed FP8 looks like next stage
