AgentBaton reverses model cascade for cheaper, accurate long agent tasks

A new approach to agent task execution, dubbed AgentBaton, reverses the typical model cascade. Instead of starting with a cheaper model and escalating to a more expensive one, AgentBaton begins with a capable, costly model for complex tasks and then hands off to a less expensive model for specific verification or fix-up work. This strategy, tested across 11 model pairs on benchmarks like Terminal-Bench 2.1 and DeepSWE, resulted in an average API cost reduction of 65.9% while largely maintaining accuracy. The study found that a cheap-first handoff approach performed worse and sometimes incurred higher costs. AI

IMPACT This method could significantly reduce operational costs for complex AI agent tasks while preserving performance.
