Microsoft's AutoSaddler automates AI agent harness optimization

Researchers from Microsoft have developed AutoSaddler, a novel system designed to automatically optimize AI agent harnesses. This method treats the harness as code and learns to patch it offline using failure traces. AutoSaddler iteratively runs tasks, diagnoses failures, generates structured patches for prompts and control logic, and validates these changes before updating. The system demonstrated significant improvements, achieving gains of 9.0 points on GAIA2, 9.6 on SWE-Bench Pro, and 10.0 on Terminal-Bench 2.0 compared to their base harnesses. AI

IMPACT Automates the optimization of AI agent harnesses, potentially leading to more efficient and capable AI systems.

    Impressive new paper from Microsoft and colleagues.

    Impressive new paper from Microsoft and colleagues. Harness design is still hand-tuned almost everywhere. This work present an automated loop to optimize the harness. They introduce AutoSaddler, which treats the agent harness as code and learns to patch it offline from failure …
