DESCRIPTION

Image generate (fast/cheap) / text-to-image / AI art. SFW, sub-5s turnaround. Four tiers backed by curated $0.01 Venice models: 'fast' (z-image-turbo, default), 'creative' (chroma), 'anime' (wai-Illustrious), 'sd35' (venice-sd35). For top-tier quality use image-generate-pro ($0.10, Flux 2 Pro / Recraft / Seedream / Qwen Image 2 Pro) or image-generate-ultra ($0.30, Google nano-banana-pro / OpenAI gpt-image-2). Returns a permanent fal-hosted PNG URL.
