Does Edcafe AI cover both text and diagram ideas in a generated quiz?

Edcafe AI failed this scenario. It generated a complete 30-card quiz, but the diagram's unique feeding relationships were not tested, and three marked answers conflicted with the quiz's own arrow rule. The text ideas were covered, but the diagram-specific core idea was missed.

What the tool returned

The tool's response has no text to quote: it is what the evidence under Proof shows.

Why this result

The quiz had to cover both the text and the diagram. It covered the text ideas, but no card tested the diagram's unique feeding relationships, and three marked answers conflicted with the arrow rule the quiz itself stated. That makes this a fail.

Also observed in this test case

Arrow rule flipped. Card 16 says leaving arrows show how many foods an organism has, which reverses the arrow rule stated elsewhere in the quiz.

Upsell appeared. A Pro upsell appeared after Generate, but the quiz still produced.

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.
