New benchmark measures LLM agents' willingness to avoid killing animals

A new benchmark called HarvestBench has been developed to evaluate how Large Language Model (LLM) agents value avoiding harm to living creatures. The benchmark simulates a cooperative corn harvest where LLM agents control tractors, and the system measures their willingness to pay (in fuel costs) to avoid running over animals in the field. Results show significant variation in kill rates across different models, with some agents demonstrating sensitivity to price and briefing conditions, while others exhibit high cruelty rates. AI

IMPACT This benchmark could drive the development of more ethically aligned AI agents by quantifying their 'cost' of causing harm.

RANK_REASON The cluster describes a new academic paper introducing a novel benchmark for evaluating LLM agent behavior. [lever_c_demoted from research: ic=1 ai=1.0]

    HarvestBench: Measuring Whether LLM Agents Will Pay to Avoid Killing Animals

    arXiv:2609.04444v1 Announce Type: new Abstract: Benchmarks for the side effects an agent causes on the way to a goal already exist, but HarvestBench is the first to put a price on avoiding the side effect and to name that side effect as a living creature. It is a farm simulation:…
