New metrics quantify LLM agent behavioral similarity and convergence

A new paper introduces two metrics, Response Pattern Similarity (RPS) and Action Graph Similarity (AGS), to quantify how similar the tool-use behaviors of different AI agents are. These metrics aim to distinguish between essential task-related actions and non-essential behavioral patterns that emerge from model distillation. The research found that models from the same provider exhibit more similar tool-use habits than those from different providers, and highlighted Kimi-K2's high similarity scores. AI
