Generate one 1024×1024 image from a short prompt (max 600 chars) with FLUX.1 [schnell] (Apache-2.0) on our Cloudflare Worker via Workers AI. Before generation we detect the medium you asked for (photo, illustration, flat vector, logo/icon, watercolor, oil painting, pencil sketch, ink, anime, comic, pixel art, 3D render, digital painting) and rewrite the prompt to honour it, with style-specific quality guidance (e.g. real lens and natural light for photos, clean 2D linework for illustrations); no medium named = natural photo. The medium is never switched and nothing unrequested is added; set style to force one, or enhance=false to use your prompt as written. Both your prompt and the final prompt go through our content screen (keyword rules + an LLM check): sexual content, minors, violence/weapons, real or identifiable people, hate and illegal content are refused with 400 and you are not charged. The image itself is not classified. Returns a base64 JPEG plus the final prompt and detected style. Capped at a small number of images per day: 503 (not charged) when used up.
