Study: Strong Scaffolding lets weak models rival frontier performance

A new study introduces AutoDesign, a system that automatically optimizes agent scaffolding (prompts, tools, validation checks) by running tasks and iteratively fixing failures. Results show that scaffolding benefits weak models the most, with gains of 5 to 19.6 points on benchmarks like PosterBench. The key takeaway: spend time engineering checks and retry logic before upgrading to a more expensive model.
