      Freely prompt artist models / concepts with open controls for size, inference steps, seed number etc. Text prompts need to manually include artist concept / model tokens which can be found in the welcome tab and beta tab (ie "an alien in the style of <ahx-model-12>"). You can also mix and match models (ie "a landscape in the style of <ahx-model-14> and <ahx-beta-4307f62>>"). To see example images or for more information see the links below.

# Old Text --> This tool allows you to run your own text prompts into fine-tuned artist concepts from an ongoing series of Stable Diffusion collaborations with visual artists linked below. Select an artist's fine-tuned concept / model from the dropdown and enter any desired text prompt. You can check out example output images and project details on the project's webpage. Additionally you can play around with more controls in the Advanced Prompting tab. <br> The images you generate here are not recorded unless you choose to share them. Please share any cool images / prompts on the community tab here or our discord server!

      This tool allows you to test out newly trained beta concepts trained by artists. To add your own beta concept see the link below. This uses free access to Google's GPUs but will require a password / key that you can get from the discord server. After a new concept / model is trained it will be automatically added to this tab when the app is redeployed.
