Features

FLUX.2 [pro] — Text-to-Image

Production-ready text-to-image with studio-grade quality and zero parameter hassle. FLUX.2 [pro] is the flagship model in the FLUX.2 family, tuned so that a good prompt is all you need—no guessing guidance scales, no step-count experiments—just reliable, campaign-ready images.


Where FLUX.2 [pro] shines

  • Always-on production pipelines

  • High-volume generation with strict brand rules

  • API and backend integrations

  • Teams that want predictable quality, not parameter juggling

  • Hero shots, key art, and other detail-critical deliverables


Key benefits

  • Ready-to-use studio quality

Produces professional-grade images without configuring steps, schedulers, or guidance values—the model’s internal optimisation makes those calls for you.

  • Stable across large batches

Delivers predictable results across many prompts and jobs, making it well suited for automated workflows, API usage, and brand-safe pipelines.

  • Frictionless iteration

A streamlined setup lets teams move quickly from prompt idea to usable creative, shortening review cycles and experiment loops.

  • Format-ready outputs

Supports JPEG for lightweight web assets, fitting both digital campaigns and print preparation.

  • Consistent reruns

Seed control allows you to recreate a previous result or explore controlled variations without touching low-level inference parameters.

  • Prompt-smart generation

Built-in prompt handling helps the model interpret complex instructions more clearly, improving coherence on multi-object, multi-character, or layout-heavy prompts.


Pricing

  • $0.03 per generated image

Parameters

Task Submission Parameters

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The positive prompt for the generation.
sizestringNo1024*1024256 ~ 1536 per dimensionThe size of the generated media in pixels (width*height).
seedintegerNo-1-1 ~ 2147483647The random seed to use for the generation. -1 means a random seed will be used.
enable_sync_modebooleanNofalse-If set to true, the function will wait for the result to be generated and uploaded before returning the response. It allows you to get the result directly in the response. This property is only available through the API.
enable_base64_outputbooleanNofalse-If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API.
