AgentTrace framework identifies LLM agents' foundation models with 96% accuracy

Researchers have developed AgentTrace, a new framework designed to identify the underlying foundation model of black-box LLM agents. This method works by injecting probes that trigger serialization failures, which are then analyzed based on their temporal sequence and recovery behaviors. AgentTrace achieves 96.0% accuracy in attribution, even distinguishing between similar models like Llama 3 8B and 70B, and remains effective against adversarial prompt obfuscation and temperature scaling. AI

IMPACT This method could enhance security and trust in autonomous AI systems by providing a way to verify the origin of LLM agents.

    AgentTrace: Execution-Level Fingerprinting of Black-Box LLM Agents

    arXiv:2610.32092v1 Announce Type: cross Abstract: Verifying the provenance of autonomous LLM agents is a critical security challenge. Existing semantic attribution is easily obfuscated by system prompts, while active watermarking conflicts with schema-constrained tool generation.…
