τ-Bench (tau2-bench) is a Python benchmark for evaluating LLM agents on tool-agent-user interaction in real-world domains like retail, airline, telecom, and banking. It scores agents on conversations with simulated users, tool calls, knowledge retrieval, and policy adherence, including voice full-duplex evaluation, with a live public leaderboard.

Use cases

  • benchmark my llm agent on tool calling and customer service tasks
  • evaluate how reliably an agent follows domain policies
  • compare models on multi-turn conversational agent tasks
  • test voice agents on real-time full-duplex conversations
  • evaluate rag pipelines on knowledge-intensive banking tasks
  • measure pass^k reliability of agent trajectories
  • reproduce published agent benchmark scores

When to choose

  • you need standardized, verifiable evaluation of tool-using conversational agents
  • you want to compare your model against a public leaderboard
  • you need both text and voice agent evaluation with realistic simulated users

When to avoid

  • you need a general-purpose agent framework for building production agents rather than evaluating them
  • your domain is unrelated to the provided retail/airline/telecom/banking scenarios and you cannot author custom tasks
  • you need cheap, fast evals - simulated user LLM calls add cost and latency
