TAU-bench Airline
Part of τ-bench (TAU-bench), a benchmark for Tool-Agent-User interaction in real-world domains. The airline domain evaluates language agents' ability to interact with users through dynamic conversations while following domain-specific rules and using API tools. Agents must handle airline-related tasks and policies reliably.
Claude Sonnet 4.5 from Anthropic currently leads the TAU-bench Airline leaderboard with a score of 0.700 across 23 evaluated AI models.
Claude Sonnet 4.5 leads with 70.0%, followed by 
MiniMax M1 80K at 62.0% and 
GLM-4.5-Air at 60.8%.
