Flux is a series of advanced generative AI models developed by Black Forest Labs, focusing on high-quality image generation and editing. Its core includes Text-to-Image (T2I) and text-driven image editing. FLUX.1 Kontext is the latest sub-series, capable of precisely modifying images through natural language, supporting complex prompts, consistency, and creative editing, with 12 billion parameters, performance comparable to or surpassing Midjourney and DALL·E 3. FLUX.1 Kontext [pro] and [dev] variants were released in May 2025, widely integrated into platforms like Replicate, supporting various call formats. - **Supports Replicate format calls**: Model prefix is black-forest-labs/, compatible with Replicate API, facilitating the deployment of image generation and editing tasks. - **Supports flux-kontext-max and flux-kontext-pro**: Professional variants of FLUX.1 Kontext, focused on text-driven editing, supporting high resolution, style consistency, and multimodal input (e.g., reference images). - **Supports OpenAI compatible Chat format calls**: For flux-kontext-max and flux-kontext-pro, supports OpenAI compatible Chat format for image generation and editing.
