FLUX.1 API - the state-of-the-art image generation model API!

The open source FLUX.1 suite of models (FLUX.1-Pro, FLUX.1-Schnell, and FLUX.1-Dev) from the Black Forest Labs are state-of-the-art text-to-image generative AI model. And now PiAPI is providing Flux-dev API and Flux-schnell API for developers around world at peak performance and cost effective rates!

Features

Image-to-Image Generation!
PiAPI will be the first to offer image-to-image generation for the FLUX APIs - allow developers and users greater flexibility when generating visuals for a variety use cases.
Seed parameter supported
Num_outputs is a useful parameter that can be used to control the number of outputs to generate. If left unused, the API will use 1 output as the default value.
Aspect_ratio parameter supported
Developers can use this parameter to vary the aspect ratios of output images, making the outputs more suitable in a variety of different use cases!
Asynchronous API Calls
The API will be designed to allow for asynchronous calls, allowing developers to "submit and forget" tasks, and fetch for the task when completed.
Accelerated Hardware Infrastructure
Our accelerated hardware infrastructure is specifically optimized for latent diffusion model inference work, ensuring workloads to be executed with maximum efficiency and minimum latency.
Custom Inference Frameworks
Our custom inference framwork used for latent diffusion model workloads focus on optimized runtime performance and resource management, preventing bottlenecks from traditional framework.
Bulk Generation Available

The perfect generation option for developers to populate their websites/apps/projects with large quantity of custom pictures from custom prompts. Contact us on Discord with your prompts and we will get back to you with a pricing and a timeline!

Simple and Flexibe Payment Plans

Our Pay-as-you-go option allows developers to test the API with free credits, and purchase credits for consumption, and manually or automatically top-up their credits as their usage varies.

Commercial Use
Given the Apache2.0 license of the FLUX.1-schnell model, all images generated from our API using that model will be available for commercial use as needed by the developers or the end-users.

Frequently asked questions

What are the FLUX.1 model suite?

The FLUX.1 model suite is developed by Black Forest Labs or (BFL for short), is led by Robin Rombach, Patrick Esser, and Andreas Blattmann, who were the original co-creators of the Stable Diffusion models. BFL is invested by A16zand other notable angel investors in the field of generative AI. BFL is on a mission to build the world's best open-source generative image and video visual models for developers, and FLUX.1 model is the first step!

There are three versions within the FLUX.1 model family: FLUX.1-pro, FLUX.1-dev, and FLUX.1-schnell.

FLUX.1-dev is open weight, guidance-distlled, efficient model for non-commercial applications. Whereas FLUX.1-schnell is openly available under the Apache2.0 license and best suited for local development and personal use.

What is the FLUX API?

The FLUX API are offered by PiAPI based on the FLUX.1-dev model and FLUX.1-schnell model. Given our accelerated hardware infrastructure and custom-developed inference framework, PiAPI is able provide APIs for these two models at very market competitive costs while maintaining performance and minimizing latency!

What type of images can I generate with FLUX.1 API?

With the recent ELO score information for the FLUX-dev and FLUX-schnell model both exceeding than that of Midjourney, the possibility of using API for image generation is quite endless. It is expected that it would be significantly impacting industries ranging from entertainment, education, product design all the way to scientific visualization.

Can I use videos generated from the FLUX-dev API for commercial purposes?

Given the Apache2.0 license of the FLUX.1-schnell model, all images generated from our API using that model will be available for commercial use as needed by the developers or the end-users. However, images generated from the API for FLUX.1-dev model will not be available for commercial use since BFL has limited that model to non-commercial use only.

Are there refunds?

No, we do not offer refunds. But when you first sign up for an account on PiAPI‘s Workspace, you will be given free credits to try our API (specifically the "Pay-as-you-go" service) before making top-ups!
