Black Forest Labs is enabling updates to the Flux AI image generator

Black Forest Labs has quickly made a name for itself as the first high-quality open source AI image generation startup – even surpassing the quality models offered by Stability AI, where the founders of Black Forest Labs previously worked. It soon became the default image generator in the Grok xAI language module as well.

Today Black Forest Labs takes this a step further, announcing the release from the FLUX Pro Finetuning APIa tool that empowers creators to customize generational AI models using their own images and concepts.

Designed for professionals in marketing, branding, storytelling and other creative industries, the API enables the personalization of the company's flagship. FLUX Pro and FLUX Ultra models with an easy-to-use approach.

Customization at a distance

The FLUX Pro Finetuning API allows users to fine-tune generative text-to-image models with five to 20 training images, optionally with text descriptions.

This process results in customized models that maintain the generational flexibility of the basic FLUX Pro models while aligning products with specific creative visions. The tool supports several modes, including “character,” “output,” “style” and “general,” making it adaptable for a wide variety of use cases.

The sophisticated models can integrate quickly with endpoints such as FLUX.1 Fill, Depth, Canny and Redux, as well as with high-resolution generation capabilities of up to four megapixels. Whether it's to create brand-consistent marketing images or detailed character art, the API enhances accuracy and flexibility in AI-generated content.

Practical applications and use cases for brands, marketers and more

Using the FLUX Pro Finetuning API, professionals can create customized models that preserve essential design elements, character consistency or brand characteristics. A survey conducted by Black Forest Labs showed that 68.9% of users preferred FLUX Pro's neat products over competing services.

Some notable applications include:

• Painting: Using FLUX.1 Web for iterative edits to update images

• Structural control: Integrates with FLUX.1 depth to enhance image generation with precise structural adjustments

• Visual branding: Ensure consistency across marketing materials and campaigns

Partnership with Burda Verlag

Black Forest Labs has partnered with Burda Verlaga leading German media and entertainment company, to demonstrate the potential of the FLUX Pro Finetuning API. BurdaVerlag's creative teams are using the tool to develop custom FLUX models suitable for their brands, such as the children's publication Lissy PONY.

With this integration, BurdaVerlag's design teams can create visuals that reflect each brand's identity while exploring new creative directions. The API has accelerated their production workflows, enabling the generation of high-quality content at scale.

Affordability and accessibility

The FLUX Pro Finetuning API is now available via API endpoints via the Flux.1 (dev) module. Prices for all FLUX modules on the Black Forest Labs API are as follows:

• FLUX 1.1 (pro) Ultra: $0.06 per photo

• FLUX 1.1 (pro): $0.04 per photo

• FLUX.1 (pro): $0.05 per photo

• FLUX.1 (dev): $0.025 per photo

Getting started is a cinch

The miniaturization process requires very little user input. Training images in supported formats (JPG, JPEG, PNG or WebP) are uploaded, with resolutions set at one megapixel for the best results. Advanced configuration options allow precise control of the training process, including feed counts, learning rates, and prompts for quick and detailed integration.

Black Forest Labs has also provided extensive resources, including a Beta Tuning Guide and Python scripts for easy implementation. Users can monitor progress, change parameters, and test results directly through API endpoints, ensuring a smooth and efficient workflow.

By combining flexibility, ease of use and professional grade results, the FLUX Pro Finetuning API sets a new benchmark for custom content creation in generational AI. With the tool now available, Black Forest Labs aims to transform the way individuals and organizations approach personalized media generation, unlocking creative possibilities on an unprecedented scale. .
