Efficient Tool Use with Chain-of-Abstraction Reasoning

Silin Gao (EPFL), Jane Dwivedi-Yu (Meta AI)

Abstract

We introduce Chain-of-Abstraction (CoA), a method for efficient tool use that separates reasoning from tool execution. CoA generates abstract reasoning chains first, then fills in tool calls, reducing redundant API calls.

How this paper contributes to solving the Zone III problem (PASF-PADE)

For Zone III agents making thousands of tool calls, efficiency matters. CoA's abstraction-first approach reduces unnecessary API calls — directly reducing cost and latency in enterprise deployments.

Why AI is not sufficient for Zone III without this

Zone III refers to high-complexity, high-risk, long-running agentic workflows — the class of enterprise AI deployments where a single failure can cascade across hundreds of steps. Standard AI models, trained to predict the next token, are not inherently designed for durable, governed, multi-step execution. This paper addresses one or more of the structural gaps that make Zone III deployments unsafe without explicit architectural intervention.
