FLUX

Editorial Review

FLUX is the rare AI-tool launch that genuinely advanced the state of the art on release. Founded by the people who built Stable Diffusion, Black Forest Labs shipped FLUX.1 in mid-2024 and FLUX.2 in November 2025 with prompt adherence and naturalism that pulled meaningfully ahead of contemporary Stable Diffusion variants. The open-weight Dev and Schnell variants made it the new default for self-hosted image generation, and the Pro variants compete head-to-head with Midjourney and Nano Banana on hosted-API quality. FLUX.1 Kontext (released 2025) added strong image-edit capabilities — given an input image, edit specific elements while preserving identity. That filled a gap the lineage previously left to ControlNet and other Stable Diffusion add-ons. For builders putting image gen in products, FLUX is the most flexible answer: open weights for self-hosting at zero marginal cost, hosted API for production scale, and quality competitive with anything closed.
