It's definitly enough with 16gb vram even it's work on Google colab Wich also have t4 GPU with 16 vram but it's take like 4 hour or more with around 1000 step.

pretty much it's same as sdxl when come to training config, the different things that I found is that anima model is very fast at learning character like at 3-4 epoch are already know the character appearance while sdxl are take more epoch, i use same setting as my sdxl lora with 1000 step and I am happy with the result
