All images used to train Chroma (Perchance T2i model) are tagged with the 'aesthetic' tag

Source: https://huggingface.co/lodestones/Chroma/discussions/72

Chroma (Perchance Text to image model) is trained on 5 million images

The tagging system for all these images include the word 'aesthetic' in the training prompt , used in this manner :

'aesthetic 0' , 'aesthetic 1' , .... 'aesthetic 10' , 'aesthetic 11' are labels used to denote the visual style in the training data

Where 'aesthetic 11' denotes (good) AI-images used for training data

Thats all we know.

This system isn't 100% accurate , but it is highly recommended you use the term 'aesthetic' at least once (preferably often) to mimic the training prompt(s) in the Chroma model.

Check the HF page for Chroma in the future on further info regarding training data / prompts you can use while generating images on the perchance website.

TLDR; use the word 'aesthetic' in your prompt to improve them for perchance text-to-image generation

Cheers!
