Black Forest Labs is a frontier AI research lab building state-of-the-art generative image models under the FLUX brand. Its core offering spans multiple model tiers — from the production-grade FLUX.2 series with 4MP photorealistic output and multi-reference control, to the ultra-fast FLUX.2 [klein] family designed for sub-second inference on capable hardware. Each model is engineered for high visual quality, precise prompt following, and creative control across both text-to-image generation and advanced image editing.
The platform is accessible in three primary ways. Developers and teams can integrate directly via a simple REST API that supports production workloads at any scale, using a credit-based pay-as-you-go pricing model starting from $0.014 per image. For experimentation and rapid iteration, the browser-based Playground allows users to test models and transform images without writing code. Organizations requiring full infrastructure control can download open weights models and deploy or fine-tune them on their own hardware under Apache 2.0 or commercial license terms.
The FLUX model lineup includes FLUX.2 [max] and [pro] for production workflows, FLUX.2 [flex] for maximum quality with adjustable controls, FLUX.1 Kontext for advanced editing and generation via natural language prompts, FLUX1.1 [pro] Ultra for ultra-high-resolution up to 4MP, and FLUX.1 Fill for targeted inpainting and outpainting. Enterprise plans are available for larger organizations seeking custom licensing, dedicated support, and integration of the FLUX API and open weights into their products and services.
- Generate photorealistic images from text prompts using production-grade FLUX models
- Edit existing images by changing objects, colors, or styles with natural language instructions
- Perform targeted inpainting to modify specific areas of an image seamlessly
- Expand images beyond their original boundaries using text-driven outpainting
- Build image generation features into applications via the FLUX REST API
- Fine-tune open weights FLUX models on custom datasets for domain-specific outputs
- Deploy FLUX models on private infrastructure for full control and no API rate limits
- Create multi-reference image compositions using up to 10 reference images simultaneously
- Experiment with different FLUX model variants in the browser playground without coding
- Generate ultra-high-resolution 4MP images for high-fidelity creative and commercial work
- Integrate AI image generation into enterprise products via custom licensing agreements
