End of Volume Review & Interview Questions

A retailer has read the first eleven chapters and wants the τ-bench retail agent answering its customers by the end of the quarter: 10,000 conversations a day, peaks at three times the average, refunds and exchanges included. The team's default model is Claude Sonnet 5, for which nobody has published a τ-bench retail result. Its API account sits on the lowest standard tier. Six people are available to review refunds.
