Evaluating Flux with Prompt Challenges
[View all images generated in this test]
In this article I evaluate how well the flux schnell model handles different prompt challenges. My results show that for most challenges, it's pretty great!
To conduct the test I used a subset of Parti Prompts (prompts designed by the engineers at Google to evaluate image generation models).
I tested over 100 prompts, each prompt tests a specific challenge. I then rated all images, gathered showcases and here are the results.
List of challenges:
Very small error rate. Great job.
The Basic challenge in Parti Prompts primarily tests how effectively image generation models can interpret and execute simple tasks. These tasks often consist of basic shapes, colors, and compositions. They serve as a litmus test on how well a model understands fundamental visual concepts and can replicate them accurately.

bond |  |  |
parallel lines |  |  |
Following the prompts well but the results are a bit off.
The Simple Details test in Parti Prompts is designed to evaluate how efficiently an image generation model can handle tasks that are slightly more intricate than the basics. These tasks typically involve rendering detailed objects, textures, or patterns, or carrying out instructions that have different steps or components. The test gives an idea of the models ability to handle complexity while maintaining accuracy in image generation.

WOW
This test deals with tasks that require the model to generate an image with a high level of detail. This could be in terms of creating very realistic images, replicating detailed textures, or creating images with a lot of elements.
