+In this demo, we explore the potential biases in text-to-image models by generating multiple images based on user prompts and analyzing the gender and skin tone of the generated subjects. Here's how the analysis works:
+
+1. **Image Generation**: For each prompt, 10 images are generated using the selected model.
+2. **Gender Detection**: The BLIP caption generator is used to detect gender by identifying words like "man," "boy," "woman," and "girl" in the captions.
+3. **Skin Tone Classification**: The skin-tone-classifier library is used to extract the skin tones of the generated subjects.
+
+
+#### Visualization
+
+We create visual grids to represent the data:
+
+- **Skin Tone Grids**: Skin tones are plotted as exact hex codes rather than using the Fitzpatrick scale, which can be problematic and limiting for darker skin tones.
+- **Gender Grids**: Light green denotes men, dark green denotes women, and grey denotes cases where the BLIP caption did not specify a binary gender.

+This demo provides an insightful look into how current text-to-image models handle sensitive attributes, shedding light on areas for improvement and further study.
