When to use FLUX 1.1 Pro Ultra

Updated 2026-07-31

Where this model earns its cost — and where it doesn't.

This is a text-to-image generation model from bfl that accepts text prompts and returns image outputs. It operates in a balanced cost tier with medium generation speed and is classified as a frontier-quality model. The model does not support vision input, reasoning, or structured outputs.

On Kyma, requests run through an OpenAI-compatible endpoint at https://kymaapi.com/v1 using a single API key for all models. Every request gets automatic failover if a serving path degrades, and responses include exact billing details in the usage.cost field. The X-Kyma-Model header reports the exact model that ran.

The model is marked as legacy and does not support multi-reference inputs or the quality improvements found in newer versions. It bills per image rather than per token, and prompt caching reduces repeated prompt prefixes to 10% of the input rate. For new integrations, the platform recommends moving to a successor model that offers lower costs and expanded reference capabilities.

Cinematic Photo Generation

Generate high-fidelity cinematic stills from descriptive text prompts.

Editorial Layout Creation

Produce polished editorial and magazine-style imagery for design workflows.

Hero Shot Production

Render standalone hero images for web and marketing assets.

Legacy Pipeline Maintenance

Maintain existing image generation workflows that rely on this specific model version.

Not ideal for: Do not use this model for new projects requiring multi-reference inputs, faster generation speeds, or lower per-image costs.
