Description

FLUX.1 Krea [dev] is a cutting-edge, open-source diffusion transformer with 12 billion parameters, developed through the collaboration of Krea and Black Forest Labs, aimed at providing exceptional aesthetic precision and photorealistic outputs while avoiding the common “AI look.” This model is fully integrated into the FLUX.1-dev ecosystem and is built upon a foundational model (flux-dev-raw) that possesses extensive world knowledge. It utilizes a two-phase post-training approach that includes supervised fine-tuning on a carefully selected combination of high-quality and synthetic samples, followed by reinforcement learning driven by human feedback based on preference data to shape its stylistic outputs. Through the innovative use of negative prompts during pre-training, along with custom loss functions designed for classifier-free guidance and specific preference labels, it demonstrates substantial enhancements in quality with fewer than one million examples, achieving these results without the need for elaborate prompts or additional LoRA modules. This approach not only elevates the model's output but also sets a new standard in the field of AI-driven visual generation.
