FLUX.1 Krea [dev] utilizes a two-stage content security strategy. In the pre-training phase, all training data is carefully screened to remove NSFW and illegal content; in the post-training phase, the developer further reduces the risk of inappropriate content generated by the model through fine-tuning techniques.
