Frequently Asked Questions

  • What does FLUX1.1 [pro] cost per image?

    Check the pricing panel on this page for today's numbers. AI Gateway tracks rates across every provider that serves FLUX1.1 [pro].

  • What pixel dimensions does FLUX1.1 [pro] produce?

    Standard FLUX.1 resolutions for this slug. See N/A for dimensions and quality tiers. Workflows that need higher resolution or raw file output should use the Ultra variant in the same generation.

  • Do existing FLUX.1 Pro prompts carry over?

    Yes. Identical prompt syntax, negative-prompt support, and generation parameters carry over. Spot-check critical prompts since quality refinements may shift outputs subtly.

  • How much quicker is it than the original FLUX.1 Pro?

    Per-image render time dropped measurably. Exact gains depend on provider infrastructure and requested dimensions. Consult available providers for provider-published benchmark figures.

  • Should a new project start here or on FLUX.2 Pro?

    If the project requires multi-reference conditioning, VLM-based scene understanding, or 4MP resolution, begin with FLUX.2 Pro. If the priority is efficient, high-volume standard-resolution generation with an established prompt ecosystem, FLUX1.1 [pro] is more economical.

  • How do I invoke FLUX1.1 [pro] through AI Gateway?

    Pass the identifier bfl/flux-pro-1.1 to generateImage from the AI SDK. The request format is shared across FLUX models on the gateway.
