Is a reason to use SD3 when Flux is much much better, with a much better license?
I don't think so. They're going to have to do a lot better than a tutorial to win people back. That said, the two Flux models being distilled making them close to impossible to fine-tune sucks too.
People have been training great Flux LoRAs for a while now, haven't they? Is a LoRA not a finetune, or have I misunderstood something?
Last I heard, LoRAs cause catastrophic forgetting in the model, and full fine-tuning doesn't really work.
Oh well, in practice I'll just continue to enjoy this (possibly forgetful and not-fully-finetunable) model then, that still gives me amazing results 😊
quite the opposite. Lora's are very effective against catastrophic forgetting, and full finetuning is very dangerous (but also much more powerful).
kohya now supports flux fine tuning. I have seen nice examples in civitai.
Those might just be LoRA merged models, not full fine-tuning. From what I heard, fine-tuning doesn't work because the models are distilled. You'd have to find a way to undistill them to train them.
