If you’re paying attention to text-to-image AI leaderboards, you may recently have noticed a mysterious model named “blueberry” topping the charts.

Well, today the cat’s out of the bag: blueberry is the codename for a new series of Flux models from our friends at Black Forest Labs.

These new models are more powerful than any other open-source image generation models out there, and they are available to run on Replicate today:

FLUX1.1 [pro] is a new model

FLUX1.1 [pro] is a new, faster, more powerful version of FLUX.1 [pro].

It generates images six times faster than its predecessor FLUX.1 [pro] with higher image quality, better prompt adherence, and more output diversity. Independent benchmarks show it generates the highest quality images compared to other open source models, as of Oct 1, 2024.

Pricing for FLUX1.1 [pro] on Replicate is $0.04 per image.

Here’s an example of how to run FLUX1.1 [pro] using Replicate’s JavaScript client:

Prompt upsampling

FLUX1.1 [pro] includes a new prompt upsampling feature. It uses a large language model to automatically expand your prompt into a longer, more detailed one. You can use prompt upsampling to get a greater variety of outputs from your prompt.

In the example below, the bottom row is generating images with the prompt “bird”, while the top row is enhancing the prompt using the upsampling feature.

The existing FLUX.1 [pro] model is now twice as fast

The existing FLUX.1 [pro] model is also getting a nice upgrade, with a new version that is twice as fast (at constant quality).

Pricing for FLUX.1 [pro] on Replicate is $0.055 per image.

Here’s an example of how to run FLUX.1 [pro] using Replicate’s JavaScript client:
