よくある質問

How much does the FLUX 1.1 [pro] API cost per generated image?

Standard FLUX 1.1 [pro] generation costs approximately $0.04 per image on the official Black Forest Labs API and major cloud hosts, while FLUX 1.1 [pro] Ultra (up to 4 megapixels with Raw photorealism mode) is typically priced around $0.06 per image.

Can FLUX 1.1 [pro] be downloaded for local ComfyUI offline use?

No—FLUX 1.1 [pro] is a proprietary cloud API model and requires 0 GB of local GPU VRAM. If you want local offline generation in ComfyUI or Forge, switch the calculator above to FLUX.1 [dev] or Apache 2.0 FLUX.1 [schnell] to check FP8/NF4 GPU requirements.

What is new in FLUX 1.1 [pro] compared to the original FLUX.1 [pro]?

FLUX 1.1 [pro] delivers up to 6x faster inference latency (~4 seconds per image) while improving prompt faithfulness, skin/lighting realism, and composition diversity, plus optional Ultra (4MP) and Raw candid photography modes.

Are images created with FLUX 1.1 [pro] cleared for commercial use?

Yes. Outputs generated through the official Black Forest Labs API and authorized commercial API endpoints include commercial usage rights subject to BFL's acceptable-use policy.
