PACE: A Proxy for Agentic Capability Evaluation

arXiv:2607.02032v1 Announce Type: cross Abstract: Evaluating LLM agents on benchmarks like SWE-Bench and GAIA can be expensive, time-consuming, and requires complex infrastructure. A single evaluation can cost thousands of dollars and take days to complete. In contrast, non-agentic LLM benchmarks that test individual capabilities (e.g., reasoning, code generation) are fast and cheap to run. In this paper, we investigate whether performance on expensive agentic benchmarks can be accurately predicted by the performance on a small, carefully selected subset of atomic evaluation instances. We intr

Why this matters
Why now

The rapid development and increasing complexity of LLM agents necessitate more efficient and cost-effective evaluation methods to accelerate progress and adoption.

Why it’s important

The high cost and time required for evaluating LLM agents are critical bottlenecks preventing faster iteration and broader integration, making efficient evaluation a key enabler.

What changes

A more efficient and accessible proxy for evaluating agentic capabilities could significantly lower the barrier to entry for LLM evaluation, speeding up research and development.
