LatencyPrism Delivers Zero-Intrusion Latency Sculpting System
Researchers present LatencyPrism, a zero-intrusion multi-platform latency-sculpting system for LLM inference that profiles latency without code changes or service restarts. Deployed across thousands of XPUs for over six months, it provides low-overhead, batch-level real-time monitoring with millisecond alerting, distinguishes workload-driven variations from anomalies and achieves an anomaly-detection F1 of 0.98. The system facilitates root-cause analysis and SLO adherence in heterogeneous production inference environments.
Key Points
- 1Implements zero-intrusion latency sculpting across XPUs, requiring no code changes or service restarts
- 2Detects anomalies with an F1-score of 0.98 and separates workload-driven variation from true issues
- 3Enables millisecond batch-level alerts and SLO adherence for heterogeneous production inference pipelines
Scoring Rationale
Strong practical validation and actionable tooling, limited by single arXiv preprint lacking wider peer-reviewed evaluation.
