Black Forest Labs is excited to announce the launch of the FLUX Pro Finetuning API, bringing unprecedented customization capabilities to our flagship FLUX Pro model line. Generative text-to-image models often do not fully capture a creator’s unique vision, and have insufficient knowledge about specific objects, brands or visual styles. With the FLUX Pro Finetuning API, creators can customize FLUX.1 [pro] with their own images and concepts to give them more control over the final results.
Examples of user-provided images with content that FLUX has no or limited knowledge of, such as specific persons, pets, clothing, stickers, and styles.
Trained on user-provided images, each FLUX Pro finetune is a user-customized FLUX Pro model. Each finetune maintains the generative versatility of the base model, but allows creators to easily reimagine user-provided content via text prompts. By enabling targeted finetuning of our highest quality models with as few as 1-5 example images, this new tool opens new horizons for customized content creation, and enables countless use cases including marketing, branding and storytelling.
Customized Content Creation at Unprecedented Quality
The FLUX Pro Finetuning represents the most powerful finetuning tool to date and sets a new industry standard for customized media creation with generative AI. In a user study we conducted, FLUX Pro finetuning results were preferred 68.9% of the time over other available finetuning services using FLUX.1 [dev].
Once a FLUX Pro finetune is created, it can be seamlessly applied across our entire model suite without any additional adaptation. This includes our most powerful models – FLUX.1 [pro] and FLUX1.1 [pro] and our complete FLUX Tools suite.
This versatility enables the creation of high-quality, customized content with resolutions up to 4 megapixels. Professional creatives and designers can now access AI tools that reliably preserve essential brand properties and style while maintaining character consistency across all generated content.
Combining finetuning with FLUX.1 Fill [pro] enables personalized inpainting for iterative editing of a given image.
Another possible application is combining finetuning with FLUX.1 Depth [pro] to unlock personalized content generation with structural control.
Customized FLUX finetunes can now be created via our newly available API Endpoint. Learn more about how to train your own finetune and optimally combine it with our most powerful models by following our Finetuning Guide.
