Flux

FLUX is Black Forest Labs' image generation model, currently considered the state-of-the-art for photorealistic AI images. Open weights for FLUX.1-dev (research/personal use) and FLUX.1-schnell (Apache 2.0 license, fully open). Generally beats Stable Diffusion XL on photorealism and prompt adherence. Available via API on Replicate, Together AI, <a href="https://fal.ai" target="_blank" rel="noopener noreferrer">fal.ai</a>, or run locally with sufficient VRAM (24GB recommended for full quality). Best for: photorealistic outputs, professional product photography, headshots, and any use case where image realism matters more than artistic style.
