Use cases

Production image generation and editing is a documented use case for FLUX.2 Pro Preview, which is described as Black Forest Labs’ recommended default for production image generation and editing.

Multi-reference editing is another documented use case, including combining two reference images in a single composition.

It is also documented as suitable for image generation tasks using text prompts, and the preview endpoints are described as the best place to start for such use cases.

Reproducible PNG output for downstream editing pipelines is a documented use case as well, with seeded generation and PNG output called out explicitly.
