About Krea 2 Large
Krea 2 Large is Krea's text-to-image model. It generates high-fidelity images from text with strong aesthetic quality and fine detail.
The model supports a range of aspect ratios, a creativity control that trades prompt adherence for more imaginative results, and seed control for reproducible generation. It also accepts optional image style references, which can be weighted to control how strongly they influence the output.
Krea 2 Large cannot be fine-tuned. For fine-tuning, see Krea 2 Raw, the open-weights checkpoint Krea released as a base for customization.

creativity | string | No | "medium" | Controls how loosely the model interprets the prompt. Higher means more creative results that may drift from the prompt; low or raw values stay closer to the prompt.rawlowmediumhigh |
