LLM planner ↔ implementer pairs 🤝 New tutorial from Alejandro AO introduces DuoBench, a Skill-shaped harness that runs Kimi K2.7, Kimi K2.6, GPT-5.5, and Claude
A new tutorial introduces DuoBench, a framework designed to evaluate the performance of Large Language Model (LLM) planner-implementer pairs. The system tests models like Kimi K2.7, Kimi K2.6, GPT-5.5, and Claude Opus 4.8 on coding tasks. Initial results suggest that while planning is inexpensive, the implementation phase incurs significant token costs, with Kimi K2.7 showing strong performance in terms of quality and cost-efficiency.

IMPACT This framework could help researchers and developers better understand and optimize the cost-performance trade-offs in LLM-driven coding tasks.
