FLUX 2 Klein 9BAI image generator
Small, open FLUX — cheap and quick. Pay only for the takes you keep — kill the rest for a full refund.
FLUX 2 Klein 9B is Black Forest Labs' compact FLUX 2 image model, released January 15, 2026. Klein is German for small: a 9B flow model with an 8B Qwen3 text embedder, distilled to four steps. It unifies text-to-image and image editing, and is known for photoreal stills you can iterate without a long wait.
Use it for fast drafts, volume stills, and edit passes before a heavier FLUX. Fair-use unlimited on Pro ($29/mo). One credit balance across 50+ models, from the web studio or from Claude, ChatGPT, and Cursor via Elyum's MCP server and REST API.
