DecisionBench introduces benchmark for agentic workflows
Researchers have launched DecisionBench, a new benchmark designed to measure delegation within long-running agentic workflows. It evaluates the ability of AI agents to effectively delegate tasks between different models.

What happened?
DecisionBench is a new benchmark focusing on emergent delegation within long-running agentic workflows. It includes a fixed set of tasks from GAIA, tau-bench, and BFCL, as well as a model pool consisting of eleven models from seven provider families. The benchmark employs a delegation interface based on "call_model" and "read_profile" to simulate task delegation.

”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”
Why it matters
The development of DecisionBench aims to objectively measure and characterise how AI agents delegate tasks. This is essential for understanding how agentic systems perform in complex scenarios, where efficient task distribution between various specialised AI models can improve outcomes in quality, cost, and latency. The benchmark enables the evaluation of adaptive profiles and multi-step delegation.
Who is affected?
This benchmark primarily affects AI researchers, developers of agentic systems, and companies using or planning to implement AI agents for complex tasks. By providing a standardised evaluation method, developers can compare and optimise their delegation strategies.
What else you should know
Three main findings at the benchmark level emerged, where average quality was statistically indistinguishable between four of the five evaluated conditions.
