New probe method detects LLM tool-calling errors

Researchers have developed a probe-based method to detect errors in how large language models (LLMs) use external tools. This technique analyzes the LLM's internal states to identify incorrect tool calls, even those missed by standard logging. The study, which evaluated 18 LLMs on the Berkeley Function Calling Leaderboard, found that probe effectiveness depends on factors like model size and post-training methods. The probes demonstrated an ability to generalize to new error types, suggesting potential for real-world deployment. AI

IMPACT This research offers a new method for improving the reliability and safety of LLMs that interact with external tools.

    The Calls are Coming from Inside the Model: Investigating Probe-based Detection of Tool-Calling Errors in LLMs

    arXiv:2608.27750v1 Announce Type: cross Abstract: The hidden states of large language models (LLMs) are known to capture rich information relating to model knowledge and behavior that can be hard to extract from examination of input and output alone. As LLM-based systems increasi…
