We mainly do full finetunes on diffusion models and their text encoders like z-image, flux2 klein to adapt them to our clients visual style and train LoRas for people and products. The quality goes up immensely if the model has a better grasp of professional visual terms. Training the right kind of leather or plastic (mainly for the pattern) helps when you are scaling to 12-16k and want 99.9% reproduction, everything becomes a texture at that size and if you don't have them trained it's a mess.
