FLUX
: How to use it, features, and the business problems it solves

How to Use

1. Choose how to use it

   For quick experimentation, use the official browser version "BFL Playground"; to embed it into your own service, use the API. FLUX is also available from many external services (image-generation platforms, ComfyUI, etc.).

2. Prepare an account / API key

   The Playground is available with account registration. For API use, select a project in the dashboard (dashboard.bfl.ai) and issue an API key.

3. Enter a prompt and generate

   Specify the content of the image you want in a prompt and generate it. Choose the model (FLUX.2 / FLUX.1 Kontext, etc.) according to your purpose.

4. Edit images (Kontext)

   Combine an existing image with text instructions to perform "in-context editing," such as partial edits or style changes.

5. Export and integrate

   Download the generated image, or integrate it as an API response into your own app's workflow.

Features

• High-quality text-to-image generation

  Well regarded for its photorealism and prompt fidelity, and used in professional production settings.

• Image editing (FLUX.1 Kontext)

  Input an image and text to make partial edits or style changes while maintaining consistency.

• Multi-reference, consistent generation (FLUX.2)

  Use up to 10 reference images to generate images with consistent characters and styles.

• Ultra-high-resolution output

  Supports high-resolution output up to about 4 megapixels.

• In-image text generation

  Generate crisp text within an image, supporting design use cases.

• Playground and API

  Offers a Playground you can try in your browser and an API for developers. Pricing is the same for both, billed by credits.

• Ecosystem integration

  Many external platforms and tools support FLUX, making it easy to incorporate into existing workflows.

Pricing

Pricing is current as of June 2026. It is usage-based with a credit system (1 credit = $0.01), and consumption varies with the generation content and model. Pricing is the same for the Playground and the API. Check the official pricing page for the latest information.

• Whether commercial use is allowed and the licensing depend on the model ([dev] / [pro], etc.). Always check the official license terms before use.

Pros and Cons

Pros

• High photorealism and prompt fidelity, with a strong reputation for quality
• Equipped with advanced features such as image editing (Kontext) and consistent multi-reference generation
• Easy to try in the Playground, and embeddable into your own service via the API
• Many external tools support it, making adoption easy

Cons

• The user interface (UI) and documentation are mainly in English
• Because it is usage-based, heavy generation requires cost management
• Licenses and commercial-use terms differ by model and need to be checked

Reviews and Reputation

• Both creators and developers highly praise it, saying "its photorealism and prompt adherence are top-class" and "Kontext's image editing is excellent."
• Some say "I switched to it as a successor to Stable Diffusion," and it has established itself as a staple among open-model offerings.
• On the other hand, the points noted as caveats are that "commercial use requires checking the model's license" and that it is "English-centric."
