WeMusic-Agent: Efficient Conversational Music Recommendation via Knowledge Internalization and Agentic Boundary Learning
Leveraging AI for Personalized Music Recommendation
Traditional Conversational Recommendation Systems (CRS) often struggle with deep user preference understanding and balancing specialized domain knowledge with flexible tool integration, leading to inefficiencies or outdated recommendations. WeMusic-Agent introduces a novel framework that integrates knowledge internalization and agentic boundary learning, enabling intelligent decision-making for internal knowledge usage versus external tool calls, significantly enhancing both efficiency and personalization.
Quantifiable Business Impact
WeMusic-Agent's innovative approach delivers substantial improvements in key performance indicators, ensuring more accurate, personalized, and efficient music recommendations.

Our Token-Soft-Scoring approach during Continual Pretraining significantly enhances the model's ability to memorize music-related entities and attributes, outperforming standard next-token prediction and RHO-1 filtering methods.
Case Study: Agentic Boundary Learning in Practice
The WeMusic-Agent system learns to intelligently decide when to use its internalized knowledge versus calling external tools through a structured, multi-stage process:
- Specialized LLM Training: Two models, one for internalized knowledge (Minternal) and one for tool calling (Magent_zero), are independently trained to capture distinct capabilities.
- Agentic Trajectory Sampling: Real-world user queries are used to identify Minternal's knowledge boundaries (in-distribution vs. out-of-distribution samples). Negative samples are then augmented with Magent_zero's tool-calling responses.
- Agentic Boundary Learning (SFT & RL): A curriculum learning approach, starting with single-turn and progressing to multi-turn dialogues, trains the final WeMusic-Agent-M1 to achieve high accuracy in tool calling while maintaining robust conversational capabilities. This ensures optimal efficiency and effectiveness in handling diverse user requests.
