Krea 2 LoRA quick starting guide

Use 15 to 20 good-quality images, train at 1024 resolution, use a 0.0001 learning rate, and start around 700 to 1000 steps.

Real person or woman character: about 700 steps
Cartoon character: about 1000 steps
Art style: about 1000 steps
Use a unique trigger word

These are proven starting settings, not fixed rules. Lower the steps if the LoRA overtrains, or increase them if the result is too weak.
