Flux 1.1 Pro Is Now Supported In Flux Labs AI

You can now access Flux 1.1 Pro in Flux Labs AI.

It’s only been two months since Black Forest Labs was launched to develop advanced state-of-the-art (SOTA) generative AI models for media such as images and videos and to push the boundaries of creativity, efficiency, and diversity.

We believe that generative AI will be a fundamental building block of all future technologies. By making our models available to a wide audience, we want to bring its benefits to everyone, educate the public and enhance trust in the safety of these models. — BFL

When I first tried Flux, I was really impressed with the level of quality, speed of image generation, prompt coherence, and its ability to render text accurately. The fact that it’s open-weight makes it an even more enticing image model for startups and indie developers like me.

In my opinion, Flux surpasses some of the most popular and powerful closed-source image generators out there, like Midjourney and Dall-E 3.

What is Flux?

Flux is a family of image models that are open-weight, meaning you can download the weights and run them locally on your PC. These models define a new state-of-the-art (SOTA) in image detail, prompt adherence, style diversity, and scene complexity for text-to-image synthesis.

Here are the four Flux model variants:

• Flux 1.1 Pro: The latest and improved version of Flux 1. It’s six times faster and with improved image quality than its predecessor.
• Flux 1.0 Pro (legacy): This is the flagship model. It delivers top-notch prompt coherence, quality, and a wide range of output diversity.
• Flux 1.0 Dev: A distilled version of Flux 1 Pro, achieving similar quality and prompt adherence while being more efficient for smaller-scale applications.
• Flux 1.0 Schnell: The fastest model. It is designed for local development and personal use, offering quick generations with moderate quality.

All public Flux 1 models employ a mix of multimodal and parallel diffusion transformer blocks and are equipped with a staggering 12 billion parameters. These models surpass earlier diffusion models by using flow matching, a method for training generative models that improves both speed and quality.

What’s New in Flux 1.1 Pro?

Flux 1.1 Pro offers a significant performance boost, delivering six times faster generation speeds than its predecessor while also improving image quality, prompt adherence, and overall diversity.

For businesses and indie developers like myself, who rely on Flux models for image generation and fine-tuning capabilities in our products, this update is a huge deal.

Check out some of the sample images generated with Flux 1.1 Pro below:

Black Forest Labs also updated the Flux 1.0 Pro model to generate the same output as before, but two times faster.

Access Flux 1.1 Pro in Flux Labs

There are many ways to generate images with Flux image models. One of them is on Flux Labs AI — a platform that lets you train image models with your own photos to generate unlimited custom images.

After you login with your Google account, head over to the image generation page and set the Flux Model to Flux 1.1 Pro.

These are the settings you can adjust to tweak the resulting image:

• Aspect ratio: Define the dimensions of your image by selecting an aspect ratio. Options include square (1:1), portrait (4:5), landscape (16:9), and more.
• Steps: This integer value controls how many iterations the AI goes through to create your image. More steps generally lead to higher-quality images but will increase computation time.
• Guidance: Also known as the Classifier-Free Guidance (CFG) scale, this parameter determines how closely the AI follows your text prompt. A higher guidance value means the AI will adhere more strictly to your description, while a lower value allows for more creative interpretation.
• Seed: Specify a numerical seed to initialize the image generation process. If you use the same seed number and prompt, the AI will produce similar images each time. Leaving it blank will generate a random seed for each image, resulting in different outputs.
• Output format: You can choose the file format of the output image between JPG, PNG, and Webp.
• Output quality: Adjust the quality of your image between 0 and 100. Higher values result in better image quality but require more processing time and may increase the file size.

In the prompt field, describe the image you want to generate. Here’s an example:

Prompt: POV shot, a photorealistic photo of a female blowing a kiss at the camera, set against Italian street background

Pretty cool, right? You can also view the images under the creations page.

Here’s another example:

Prompt: An image of a cute dog lying on a fluffy circle pillow, smiling for a photoshoot

Awesome! The generation speed is fast, and the result looks absolutely impressive. The details are sharp, the colors are vibrant, and the images look like they were taken by a professional photographer.

An Interesting Trick with Flux 1.1 Pro

Here’s an interesting little trick to trigger Flux 1.1 Pro to generate a photorealistic image. If you add the keyword “IMG_1025.HEIC” into the prompt, you’ll get an incredibly realistic image.

Check out this example:

Prompt: IMG_1025.HEIC an image of a woman taking a selfie

Here are some of the results:

This is really impressive. The prompt also works with subjects other than people.

Final Thoughts

In my four years of experimenting with AI image generators—both open-source and closed-source—I've never been as impressed as I am with the Flux models. Even though Flux has only been around for a few weeks, it’s already proving to be the king of all image models.

I wholeheartedly encourage you to test Flux 1.1 Pro on Flux Labs AI. When you sign up, you’ll receive 10 free credits, which should allow you to generate three free images with Flux 1.1 Pro. If you like the tool, you can always subscribe to the paid tier to generate more images and be able to try the model training.

I’m thrilled and proud that Flux Labs AI is now supporting the latest Flux model. The API is straightforward to integrate, and the cost per generation is quite affordable, making it accessible for projects of all sizes.

Black Forest Labs is already planning to release a text-to-video soon. Once this comes out, it will also be integrated into Flux Labs, and I can’t wait for that day to happen.
