An experiment wiring four Claude models together for the Terminal-Bench 2.1 benchmark revealed significant drawbacks to multi-model orchestration. The setup, which aimed to use a powerful model for oversight and cheaper models for tasks, resulted in the Opus model refusing valid security-related commands. Additionally, a skipped review step and inefficient delegation led to increased costs and reduced success rates compared to single-model approaches. The author found that the four-model system solved 78% of tasks at a cost of $1,178, placing it seventh overall and significantly more expensive than top-performing single models. AI
