Flux 1.1 Pro — AI Image Generator
Photographic realism at a sensible cost. The generation that made prompt adherence reliable — it follows multi-clause instructions closely and produces convincing skin, fabric and natural light.
Flux 1.1 Pro is made by Black Forest Labs. The generation that made prompt adherence reliable — it follows multi-clause instructions closely and produces convincing skin, fabric and natural light.
Where it struggles: Superseded by the Flux 2 family for the hardest prompts, and it renders text no better than any other model of its generation.
Reach for it when the job is photographic realism at a sensible cost. For anything else, the model directory has a comparison of the alternatives — picking by job rather than by version number is most of what separates a good result from an expensive one.

Prompting Flux 1.1 Pro
- Front-load the subject and describe the light. This model responds to photographic vocabulary — focal length, time of day, direction of light — more than to adjectives.
- Put the subject in the first few words — every model here weights the start of a prompt most heavily.
- Describe the lighting explicitly. It is the change that most reliably moves output towards the photographic.
- Generate at the aspect ratio you need rather than cropping afterwards, which costs you pixels and composition.
