Open-Source Image Model FLUX.1-Krea [dev]: Breaking Free from the 'AI Look'

We're releasing the open-source version of FLUX.1-Krea [dev], our first image model trained in collaboration with Black Forest Labs. This model prioritizes aesthetic control and image quality, seamlessly integrating with the existing FLUX.1-dev ecosystem. Unlike most image models, FLUX.1-Krea was developed with specific aesthetic preferences in mind, rather than solely focusing on technical benchmarks. This technical report details the model's development, including insights into pre-training and post-training, and future research directions. The key focus is on overcoming the common 'AI look' in generated images – blurry backgrounds, waxy skin textures, etc. – achieving high-quality results aligned with human aesthetic standards through curated datasets and reinforcement learning.
