Tool Use (Agentic) Benchmarks

10. TAU-Bench

τ-bench actively evaluates language agents on their ability to interact with (simulated) human users and programmatic APIs while adhering to domain-specific policies. Unlike existing benchmarks that often feature simplified instruction-following setups, τ-bench emulates dynamic conversations between a user (simulated by language models) and a language agent equipped with domain-specific API tools and policy guidelines. This benchmark employs a modular framework that includes realistic databases and APIs, domain-specific policy documents, and instructions for diverse user scenarios with corresponding ground truth annotations. A key feature of τ-bench is its evaluation process, which compares the database state at the end of a conversation with the annotated goal state, allowing for an objective measurement of the agent’s decision-making.

The benchmark also introduces a new metric, pass^k, to evaluate the reliability of agent behavior over multiple trials, highlighting the need for agents that can act consistently and follow rules reliably in real-world applications. Initial experiments show that even state-of-the-art function calling agents struggle with complex reasoning, policy adherence, and handling compound requests.

τ-bench is an innovative benchmark where an agent engages with database API tools and an LM-simulated user to accomplish tasks. It evaluates the agent’s capability to gather and convey pertinent information to and from users through multiple interactions, while also testing its ability to solve intricate issues in real-time, ensuring adherence to guidelines outlined in a domain-specific policy document. In the τ-airline task, the agent must reject a user’s request to change a basic economy flight based on domain policies and then propose an alternative solution—canceling and rebooking. This task requires the agent to apply zero-shot reasoning in a complex environment that involves databases, rules, and user intents.

Language Understanding and Question Answering Benchmark
