Black Forest Labs 
WaveSpeed Fast text-to-image generation with flexible outputs
FLUX.2 [turbo] is an image generation model developed by Black Forest Labs, designed to convert text descriptions into images across a wide range of styles including photorealistic scenes, illustrations, concept art, and character design. The model supports resolutions up to 2K and 4MP output, with a context window of 10,000 tokens for prompt input. It accepts select and seed inputs, giving users control over style options and reproducibility of results.
The model is positioned for workflows where generation speed is a priority, producing images in approximately 10 seconds at 4MP resolution. It supports multiple aspect ratios including 1:1, 16:9, 9:16, 4:3, and 3:4, making it adaptable for different creative and commercial formats. FLUX.2 [turbo] is well-suited for graphic designers, visual marketers, and developers integrating image generation into applications via API.
