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.
