Stop Comparing LLM Agents Without Disclosing the Harness
A new position paper argues that current methods for evaluating Large Language Model (LLM) agents are flawed. The paper introduces the "Binding Constraint Thesis," which posits that the infrastructure layer, or "harness," used to manage LLM agents significantly impacts their performance, often more than the model itself. Researchers propose a new evaluation framework that accounts for harness configuration to provide more accurate and less misleading comparisons of LLM agent capabilities. AI
