Δτ-Bench tests agents on ever-changing tool ecosystems
What is Δτ-Bench: Pushing Agents Toward a Moving Capability?
Δτ-Bench is an open-source benchmark that runs agents through a simulated world where the set of available tools constantly evolves. It forces agents to adapt when familiar services disappear or new, more efficient ones appear.
Who it is for
Researchers and developers building autonomous AI agents should care because it lets them measure robustness to real-world tool churn.
