New SSR framework improves AI agent performance by optimizing task evidence selection

Researchers have developed a new framework called Successive Scale Racing (SSR) to improve the performance of AI agents by optimizing their instructions and tool usage. Existing methods suffer from performance degradation as the number of training tasks increases, due to suboptimal evidence selection. SSR addresses this by adaptively searching for optimal evidence combinations in each evolution round, constructing diverse combinations based on task quality and coverage, and efficiently evaluating candidate harnesses. SSR has demonstrated state-of-the-art results across three benchmarks, steadily improving performance with a larger task pool while reducing validation executions by 60%. AI

IMPACT This research could lead to more robust and efficient AI agents capable of handling a wider range of tasks without performance degradation.

    Forging More Tasks into Better Harnesses: Agentic Harness Evolution via Successive Scale Racing

    arXiv:2610.28815v1 Announce Type: new Abstract: Agentic harness evolution optimizes an agent's instructions, tools, and control flow by using its task execution experiences as evolving evidence. While more evolution tasks should intuitively improve performance, our preliminary st…
