Researchers introduce NTILC, a neural framework that replaces in-context tool registry lookups with learned latent retrieval for language model agents. The approach reduces context token consumption by over 95% and inference latency by up to 74% while maintaining selection accuracy through signature-aware optimization.
Researchers propose a reinforcement learning framework that enables medical AI agents to achieve synergistic tool use by selecting appropriate diagnostic and treatment tools on a per-instance basis rather than relying on single fixed tools. The approach addresses the critical challenge that individual medical tools frequently fail on difficult cases, which conventional task-level selection cannot overcome, potentially improving safety and reliability in clinical AI systems.
Researchers propose Bits-over-Random (BoR), a chance-corrected metric to determine optimal tool shortlist sizes for LLM agents, and develop a reinforcement learning approach that dynamically adjusts how many tools to show per query. Testing across benchmarks with 20-3,251 tools demonstrates that adaptive shortlists significantly improve both tool retrieval and LLM selection accuracy while reducing cognitive overload.
Researchers propose Causal Minimal Tool Filtering (CMTF), a training-free method that improves LLM agent reliability by exposing only necessary tools at each step rather than entire tool menus. The approach reduces token usage by 90% and tool exposure from 100 to 1 per step while maintaining task success rates.
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.
