FLUX.1 [schnell] is a state-of-the-art text-to-image generation model designed to create high-quality images from textual descriptions. With a robust architecture of 12 billion parameters, it leverages advanced techniques to produce images that rival those generated by leading closed-source models.
FLUX.1 [schnell] is ideal for applications in graphic design, digital art, and rapid prototyping where high-quality image generation is required. It is suitable for both individual creators and commercial developers looking to integrate advanced image synthesis capabilities into their projects.
API Pricing:
The model primarily supports English but can handle text prompts in multiple languages, depending on the complexity of the input.
FLUX.1 [schnell] employs a hybrid architecture combining multimodal and parallel diffusion transformer blocks. This innovative structure allows for effective flow matching and enhances the model's ability to generate detailed images that align closely with user prompts.
The model was trained on a diverse dataset sourced from various online platforms, ensuring a broad representation of visual styles and concepts. The exact size of the dataset is not specified, but it includes millions of images paired with descriptive text.
FLUX.1 [schnell] utilizes a large-scale dataset that emphasizes diversity, which is crucial for generating a wide range of images. The model's training data is designed to cover various contexts, styles, and scenarios to improve its robustness.
The model's knowledge is current as of August 2024, which impacts its understanding of contemporary references and trends.
While efforts have been made to ensure a diverse training dataset, the model may still reflect existing societal biases inherent in the data. Users are encouraged to apply ethical considerations when deploying the model.

Flux Schnell takes image, text as input and returns image.
Flux Schnell is priced at $0.0039 / MP (variable).
Flux Schnell is billed per generation — a fixed charge per output rather than by prompt length.
Yes, Flux Schnell accepts image input as well as a text prompt.
Flux Schnell was built by Black Forest Labs.
Send a request to https://api.aimlapi.com/v1/images/generations with flux/schnell as the model id.
Yes. Flux Schnell is served through AI/ML API, so the same key and endpoint format used for other models applies.
