LLM music agent Melo improves NetEase Cloud Music recommendations

Researchers have developed Melo, an LLM-powered music recommendation agent deployed on NetEase Cloud Music. Melo utilizes a deterministic state graph and a prompt-driven orchestration policy, focusing on error detection and recovery rather than solely on the LLM's intelligence. Key innovations include inference-time entity grounding to verify interpretations against the search index and reflective retry to address failure modes like entity hallucination and long-tail degradation. An A/B test showed Melo improved playlist retention and engagement metrics, with offline analysis highlighting significant reductions in entity misidentification and effective recovery from system failures.

IMPACT Demonstrates practical application of LLMs in large-scale recommendation systems by focusing on reliability and error correction.

    Melo: A Production LLM-Powered Music Recommendation Agent

    We describe Melo, an LLM-powered music recommendation agent deployed on NetEase Cloud Music. Melo is structured as a deterministic five-node state graph over heterogeneous tools, with a prompt- and state-machine-driven orchestration policy rather than a fine-tuned controller. At …
