FLUX1.1 [pro] is the iterative successor to FLUX.1 Pro with quicker renders, tighter prompt adherence, and preserved aesthetic consistency. It's built for teams running high-volume digital image pipelines at standard resolutions.

const result = await generateImage({ model: 'bfl/flux-pro-1.1', prompt: 'A red balloon on a wooden table.'});FLUX1.1 [pro] shipped on October 1, 2024 as a targeted refinement of FLUX.1 Pro. The underlying architecture and prompt contract didn't change. The improvements are render speed and output fidelity at standard resolutions.
Render velocity matters for production pipelines. Every queued image completes sooner than on the original Pro, and that margin compounds across thousands of generations. Studios cycling through advertising variants, catalog photography, or social-media assets translate per-image savings directly into shorter pipeline runs.
Prompt fidelity improved alongside speed. Descriptions with multiple subjects, explicit spatial arrangements, and targeted lighting conditions resolve with greater consistency. The FLUX.1 visual signature carries over intact, so calibrated prompts and LoRAs trained on FLUX.1 outputs transfer without rework.
This model generates at standard pixel dimensions. If your workflow requires higher resolution output, raw file formats, or the expanded density needed for print and physical media, use the Ultra variant in the same generation.
