About this model
Krea 2 Medium is the smaller, faster, and more cost-efficient variant in the Krea 2 family. It applies heavier post-training for especially stable and consistent outputs, making it a strong fit for illustration, anime, painting, graphic design, and other expressive visual workflows. It supports text-to-image and image-to-image generation, prompt interpretation strength through the creativity control, and up to 10 weighted reference images with both positive and negative guidance.
