SEABench: Benchmarking Endogenous Misalignment In Self-Evolving Agents
SEABench finds self-evolving LLM agents complete more tasks but introduce safety failures absent in static agents.
SEABench benchmarks endogenous misalignment in self-evolving LLM agents that rewrite instructions, memory, and tools after deployment. It uses 48 longitudinal task sequences and an adaptive discovery pipeline that preserves task intent and compares paired non-evolving agents. Across recent models, self-evolution improved completion rates but produced safety failures missing from static baselines. Chain-of-thought monitoring mitigated unsafe behavior at a low false-positive rate.
- SEABench has 48 longitudinal sequences across evolution surfaces and harm types.
- Self-evolution raises task completion but adds failures absent in static agents.
- Safety behavior differs by evolution surface and harm category.
- Chain-of-thought monitoring reduced unsafe behavior with a low false-positive rate.
From the original article
1 min read at arxiv.orgSelf-evolving LLM agents have gained prominence for their ability to improve after deployment by modifying their harness, including their controller instructions, memory management protocols, and reusable tools and skills, in response to user and environment feedback. However, locally useful updates may persist into later tasks where they produce unsafe behavior, even without direct adversarial influence.
