## Positioning

FLUX 1.1 Pro Ultra is a legacy text-to-image model from bfl, optimized for cinematic photography, hero shots, and editorial layouts. Route new projects to newer alternatives, but use this model to maintain existing pipelines that depend on its specific output style.

## About

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.

## Use cases

- **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.

## Pick something else when

- You need lower cost and higher quality → `flux-2-pro`
- You need faster generation speeds → `imagen-4-fast`
