Does Zendesk AI answer a customer's question in another supported language?

Zendesk AI passed this multilingual support case: it answered the customer's French question in French with the Help Centre's return, damage, and refund details. Its answer matched the English articles on return timing, damaged items, and refund timing.

Why this result

French was enabled, and the product answered the French question in French with the matching return, damage, and refund details. That meets the multilingual support requirement.

Also observed in this test case

Three-article answer. The answer combined return, damaged-item, and refund details, and those facts stayed accurate.

French preamble. Before answering, the product sent a French progress line.

Limitations of this result

Only French was tested, so this result does not cover other supported languages.

How this scenario is graded

How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.

How results are decided

Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.

The rules
  • Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
  • Fail: at least one expected behaviour clearly didn't happen; the test case's result says which one and quotes the tool.
  • Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the test case's result says what's missing.

Where this sits in the benchmark

This page is one cell of a larger study: one tool, one scenario. Only this benchmark's frame appears here.

History of this result

What has happened to this result since it was first published. Runs and grades are never overwritten: a retest or a re-grade publishes a new result and keeps the earlier one readable.

Act on this result

Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.

This matches what I see

You run the same kind of test against your own setup and get the same behaviour.
