FLUX.2 — Photoreal Image Generation & Multi-Reference Editing
FLUX.2 is Black Forest Labs' image model: photoreal detail, accurate text rendering, and multi-reference editing that keeps characters, products, and styles consistent across up to 8 images. Two tiers — Pro for fast production, Flex for max quality — and you call FLUX.2 through reApi's OpenAI-compatible API.

What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Advertising creatives with on-brand text
FLUX.2 renders photoreal scenes and the headline copy together — a sports campaign, a product hero, a launch poster — with the text spelled right and laid out where you asked. Write the scene and the line in your prompt, pick the aspect ratio, and FLUX.2 composes a finished, brand-ready creative in one generation.

Photorealism in any era or style
From a grainy 1990s film snapshot to a clean studio shot, FLUX.2 nails the look — lens, lighting, grain, and color of the era you describe. It is convincing enough for stock-style imagery, period scenes, and lifestyle photography, so the output reads as a real photo rather than a render.
Multi-reference editing, kept consistent
Attach up to eight reference images and FLUX.2 keeps the same character, product, or style across the result — swap a scene, combine elements, or restyle while staying on-model. Paired with its sharp in-image text, it is built for campaigns and catalogs where consistency and legible type both matter.

Why reAPI
Photoreal, with text that holds up
FLUX.2 pairs convincing photorealism with accurate in-image text — fine typography, infographics, UI layouts, and small fonts that stay sharp. It is the combination most image models miss, and it ships through the same request to /api/v1/images/generations.
Multi-reference consistency
Combine up to 8 reference images and FLUX.2 keeps characters, products, and styles consistent across the output. Text-to-image and image-to-image run on the same surface — attach input_urls to edit, omit them to generate.
Pro and Flex, async-first
Pick Pro for fast, stable, lower-cost production or Flex for maximum quality. 1 credit equals $0.001 USD and you pay per image by tier and resolution. Submit a FLUX.2 task, poll until complete; the JSON matches the OpenAI image-generations contract, so adding FLUX.2 is a model-id change.

Integrate FLUX.2 in three steps
- step 01
Create an API key
Sign up at reApi and grab an API key. Free signup credits cover plenty of FLUX.2 generations — start on the Pro tier before you top up.
Open - step 02
Submit a generation
POST to /api/v1/images/generations with model: flux-2 (or flux-2-flex), a prompt, and optional aspect_ratio / resolution / input_urls. FLUX.2 returns a task_id immediately — add input_urls to edit instead of generate.
Open - step 03
Poll the result
GET /api/v1/tasks/:id until status is completed. The FLUX.2 response carries the image URL; mirror it to your own storage if you need it long term, since generated links expire.
