Krea 2 Raw - Oxen.ai

Try Krea 2 Raw in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: krea-2-raw Krea 2 Raw is the undistilled open-weights checkpoint of Krea’s Krea 2 text-to-image model, taken from mid-training and released specifically as a base for fine-tuning, LoRA training, and post-training. Because it has no distillation or post-training applied, it is diverse and malleable: train a LoRA on it to capture a specific aesthetic such as product photography, architectural renders, or editorial illustration. It can be deployed for dedicated inference (of the base model or a fine-tuned checkpoint); for always-on hosted inference the distilled Krea 2 Large model is the better fit.

Metric	Value
Parameter Count	12.9 billion
Mixture of Experts	No
Context Length	Unknown
Multilingual	Unknown
Quantized*	No

*Quantization is specific to the inference provider and the model may be offered with different quantization levels by other providers.
