The invention discloses a multi-
modal music recommendation method and device based on a
large model, equipment and a medium. The method comprises the following steps: acquiring music interaction representation information and a user interaction behavior; carrying out abstract extraction on the music interaction representation information to obtain a multi-
modal representation abstract; time division is carried out on the user interaction behavior based on the multi-
modal representation abstract, a plurality of
interaction time slices are obtained, and the
interaction time slices correspond to the multi-modal representation abstract; and performing user recommendation prediction on the multi-modal representation abstract corresponding to each
interaction time slice through a preset large
language model to obtain user recommendation music. According to the embodiment of the invention, the multi-modal representation abstract is extracted, the
interaction history, the social dialogue and the user identity data are fused into the slice preference description within the time
granularity, and the music matched with the user is predicted through the
large model, so that the music recommendation precision is effectively improved, and the user experience is enhanced.
