Model Details

Model Description

The model consists of a music encoder MERT-v1-300M, a natural language decoder vicuna-7b-delta-v0, and a linear projection laer between the two.

This checkpoint of MusiLingo is developed on the MusicInstruct (MI)-long and can answer long instructions with music raw audio, such as querying about the subjective feelings etc. You can use the MI dataset for the following demo
