FLUX 1.1 Pro Ultra is an image generation model built by Black Forest Labs. Routed through external models — ~500 tokens per image (50% markup over upstream cost).
FLUX 1.1 Pro Ultra works well for general-purpose image generation, illustration, and product visuals. Try the sample prompts above to see its strengths.
About 5,000 tokens per image. $1 buys 750,000 tokens, and a free Free.ai account includes 10,000 signup tokens plus a daily refill, so most users can try FLUX 1.1 Pro Ultra without spending anything.
It depends on the prompt. Free.ai lets you compare FLUX 1.1 Pro Ultra side-by-side with any other model at /image/compare/ — pick a sibling from the alternatives list to see how they differ on the same input.
Yes. Free.ai does not add watermarks and the outputs are yours to use commercially. See /models/flux-pro-v11-ultra/ for the full breakdown.
On Free.ai, FLUX 1.1 Pro Ultra supports 1:1 (square), 16:9 (landscape), 9:16 (portrait), 4:3, and 3:4. Pick the ratio in the form above before generating.
Most images come back in 5-25 seconds depending on the model and current GPU load. The result appears inline; signed-in users can also Add to queue to close the tab and get notified when it lands.
Yes — pick 1, 2, or 4 in the count field. Each image deducts about 5,000 tokens. For larger batches use /image/generate/ which fans out the same prompt across multiple models in parallel.
Free.ai does not train models on your prompts. Self-hosted models stay on our GPUs. Premium models route to the upstream provider for inference. Either way we never resell your data.
Yes. POST to /v1/image/generate/ with model="premium/flux-pro/v1.1-ultra" and include your Bearer token. Full reference: /api/.
FLUX 1.1 Pro Ultra is a premium model served by an external provider, so self-hosting is not available. Free.ai exposes it with token-based pricing instead.
Free accounts get 10,000 signup tokens plus a daily pool. When that runs out, top up starting at $1 (750K tokens) — no subscription required.
