| About the model: Riffusion is a latent text-to-image diffusion model capable of generating spectrogram images given any text input. These spectrograms can be converted into audio clips. | |
| <br />— | |
| <br />The Riffusion model was created by fine-tuning the Stable-Diffusion-v1-5 checkpoint. | |
| <br />— | |
| <br />The model is intended for research purposes only. Possible research areas and tasks include | |
| generation of artworks, audio, and use in creative processes, applications in educational or creative tools, research on generative models. | |
