You can generate up to 30 seconds of audio. We present 4 model variations: 1. Melody -- a music generation model capable of generating music condition on text and melody inputs. **Note**, you can also use text only. 2. Small -- a 300M transformer decoder conditioned on text only. 3. Medium -- a 1.5B transformer decoder conditioned on text only. 4. Large -- a 3.3B transformer decoder conditioned on text only (might OOM for the longest sequences.) When using `melody`, ou can optionaly provide a reference audio from which a broad melody will be extracted. The model will then try to follow both the description and melody provided. You can also use your own GPU or a Google Colab by following the instructions on our repo. See [github.com/facebookresearch/audiocraft](https://github.com/facebookresearch/audiocraft) for more details.
