FLUX
FLUX by Black Forest Labs is a fast, high-quality image generation family known for photorealistic output and excellent prompt adherence. Variants span free-tier dev models to ultra-resolution Pro outputs.
FLUX is one of the most popular open-weight image generation architectures. FLUX.2 is the latest base model with improved quality over the original FLUX.1 — fast and lightweight, ideal for everyday drafts. FLUX.2 Pro adds enhanced detail and coherence for professional use. FLUX [dev] Krea is a community-tuned variant with distinctive aesthetic qualities. FLUX1.1 [pro] delivers ultra-high resolution outputs for production work. All variants excel at photorealism, text rendering, and following complex multi-part prompts accurately. On Astorie, FLUX integrates with FLUX Kontext for character consistency workflows — generate a hero image with FLUX.2 Pro, then use Kontext to produce variations that maintain the same subject identity across an entire campaign.
