FLUX by Black Forest Labs
FLUX is a family of image and video generation models from Black Forest Labs, available through an API, a playground and open weights for self-hosting.
About this tool
FLUX is the model family developed by Black Forest Labs. It is known for image generation that handles complex prompts and readable text inside images, and it now also covers image editing, video clips with optional synchronised audio, and models for robotics. Many products and apps use FLUX models behind the scenes.
There are three ways to use it. You can experiment in Black Forest Labs’ playground, call the models through an API priced per generation with no subscription, or download open-weight versions and run them on your own infrastructure. Open models come with different licences, including non-commercial ones, so self-hosting requires checking the licence of each model.
What you can do
Image generation and editing
Generate images in many styles, combine references, place elements with boxes and perform targeted edits such as outpainting or erasing.
Text rendering
FLUX models are designed to render text accurately inside images, which helps for posters, packaging and mock-ups.
Video with audio
Recent models generate clips from text, images or keyframes, with optional speech, effects and ambience rendered together.
API and open weights
Use a production API billed per generation, or deploy open-weight models yourself with full control over fine-tuning.
Who is it for?
- A developer adds image generation to an app through the FLUX API.
- A design team creates poster concepts that need legible headline text.
- A company fine-tunes an open-weight FLUX model on its own servers.
Before you choose
Open-weight FLUX models use different licences, some non-commercial; confirm the licence before using a self-hosted model in a product.
Per-generation pricing is simple but scales with volume; estimate monthly usage and compare enterprise terms for high throughput.
