arXiv:2605.26112v1 Announce Type: cross Abstract: This paper studies the next major bottleneck in agentic AI as system scaling, not only model scaling: the design of auditable, persistent, modular, and verifiable architectures around foundation models. We refer to this shift as scaling the harness: treating the structured execution layer around a foundation model as a first-class object of design, evaluation, and optimization. Although recent large language models enable agents to use tools, retrieve information, maintain memory, and execute long-horizon workflows, evaluation remains largely m
The rapid advancement of large language models has enabled increasingly complex agentic behaviors, making the 'harness' around them the next critical challenge for robust and reliable AI systems.
This paper highlights a critical pivot point for AI development, moving beyond raw model capability to the architectural maturity required for safe, auditable, and production-ready autonomous agents.
The focus of AI research and development shifts from purely scaling model parameters to engineering robust, verifiable, and modular system architectures for agentic AI applications.
