Outcome-Aware Tool Selection for Semantic Routers: Latency-Constrained Learning Without LLM Inference
🤖AI Summary
Researchers propose Outcome-Aware Tool Selection (OATS), a method to improve tool selection in LLM inference gateways by interpolating tool embeddings toward successful query centroids without adding latency. The approach improves tool selection accuracy on benchmarks while maintaining single-digit millisecond CPU processing times.
Key Takeaways
- →OATS improves tool selection accuracy from 0.869 to 0.940 NDCG@5 on MetaTool benchmark without adding parameters or latency.
- →The method works offline by adjusting tool embeddings based on historical success patterns, adding zero cost at serving time.
- →Learned extensions like MLP re-rankers only help when outcome data is dense relative to the tool set size.
- →All mechanisms operate within single-digit millisecond CPU budgets, making them practical for high-scale deployment.
- →The research addresses a critical bottleneck in LLM inference where milliseconds of latency compound across millions of requests.
