What is TauBench V3 Airline?

τ-bench Retail simulates a customer-service agent in a retail business. The model talks to a simulated user and must use the company's tools (orders, refunds, policy rules) to actually solve the customer's problem. Only when the database state ends up exactly right does the task count as solved.

What does it test?

  • calling tools with correct arguments
  • following written policies while serving the simulated customer
  • multi-turn conversation behaviour (asking, confirming, acting)
  • correct final database results, not just polite replies
