DecisionBench: A Benchmark for Emergent Delegation in Long-Horizon Agentic Workflows

arXiv:2605.19099v1 Announce Type: new Abstract: We introduce DecisionBench, a benchmark substrate for emergent delegation in long-horizon agentic workflows. The substrate fixes a task suite (GAIA, tau-bench, BFCL multi-turn), a peer-model pool (11 models, 7 vendor families), a delegation interface (call_model plus an optional read_profile channel), a deterministic skill-annotation layer, and a multi-axis metric suite covering quality, cost, latency, delegation rate, routing fidelity-at-k, vendor self-preference, and a counterfactual-delegation ceiling. The substrate is agnostic to how peer inf

Why this matters
Why now

The proliferation of advanced AI models necessitates robust benchmarking for emergent capabilities like delegation in complex agentic workflows, moving beyond simpler task evaluations.

Why it’s important

A strategic reader should care because this benchmark directly measures the efficacy and risks of autonomous AI agents in real-world scenarios, impacting future AI development and deployment strategies.

What changes

The introduction of DecisionBench offers a standardized, multi-faceted evaluation framework for emergent delegation, enabling more rigorous comparison and development of agentic systems.

Winners
  • · AI Agent developers
