FLUX.1 Krea 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.

FLUX.1 Kontext
FLUX.1 Kontext is a collection of generative flow matching models created by Black Forest Labs that empowers users to both generate and modify images through the use of text and image prompts. This innovative multimodal system streamlines in-context image generation, allowing for the effortless extraction and alteration of visual ideas to create cohesive outputs. In contrast to conventional text-to-image models, FLUX.1 Kontext combines immediate text-driven image editing with text-to-image generation, providing features such as maintaining character consistency, understanding context, and enabling localized edits. Users have the ability to make precise changes to certain aspects of an image without disrupting the overall composition, retain distinctive styles from reference images, and continuously enhance their creations with minimal delay. Moreover, this flexibility opens up new avenues for creativity, allowing artists to explore and experiment with their visual storytelling.

FLUX.2
FLUX.2 advances the FLUX model family with major improvements in realism, prompt adherence, and world knowledge, enabling it to produce coherent lighting, spatial logic, and accurate material properties. It offers multi-reference generation with support for up to 10 images, allowing creators to maintain continuity across characters, products, and environments. The model reliably handles complex text, detailed typography, and branding requirements, making it suitable for marketing, design, and enterprise workflows. Editing capabilities reach resolutions up to 4 megapixels, preserving fine structure and stylistic fidelity. FLUX.2 is built on a latent flow matching architecture, combining a Mistral-3 based vision-language model with a rectified-flow transformer to unify generation and editing. Its variants—FLUX.2 [pro], FLUX.2 [flex], FLUX.2 [dev], and the upcoming FLUX.2 [klein]—offer a full spectrum of performance and control for teams of all sizes. Developers can self-host open weights, integrate via API, or tune generation parameters for full-stack customization. In every configuration, FLUX.2 is designed to radically improve productivity while lowering the cost of high-quality image creation.
