 # Distilgpt2 Stable Diffusion Model Card
-Distilgpt2 Stable Diffusion is a text-to-text model used to generate creative and coherent prompts given any text.
+Distilgpt2 Stable Diffusion is a text-to-text model used to generate creative and coherent prompts for text-to-image models, given any text.
 This model was finetuned on 2.03M stable diffusion prompts from [Stable Diffusion discord](https://huggingface.co/datasets/bartman081523/stable-diffusion-discord-prompts), [Lexica.art](https://huggingface.co/datasets/Gustavosta/Stable-Diffusion-Prompts), and (my hand-picked) [Krea.ai](./krea.ai.txt). I filtered the hand-picked prompts based on the output results from Stable Diffusion v1.4.
 
+Compared to other prompt generation models using GPT2, this one runs with 50% faster forwardpropagation and 40% less disk space & RAM.
