The model can generate up to 30 seconds of audio in one pass. It is now possible to extend the generation by feeding back the end of the previous chunk of audio. This can take a long time, and the model might lose consistency. The model might also decide at arbitrary positions that the song ends. **WARNING:** Choosing long durations will take a long time to generate (2min might take ~10min). An overlap of 12 seconds is kept with the previously generated chunk, and 18 "new" seconds are generated each time. 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.
