Can LlamaParse extract a legitimately empty set?

LlamaParse passed this empty-set extraction case. It returned an empty required array for the damage-exceptions field, with the source page saying nothing was reported and no invented member or marker text added.

The test case

Each test case is judged on its own: Pass, Fail, Not gradable, or Untested. The scenario result above counts this row.

Why this result

The document said nothing was reported, and the product returned an empty required array instead of inventing a member or turning the marker sentence into data.

Also observed on this row

No citation. The empty field has no source citation in the extraction metadata.

Timing gap. The job's created and updated timestamps are 10.9 seconds apart.

Limitations of this result

Only one field is visible in the captured result panel; the rest are not shown.

The screenshot shows only the damage-exceptions field; other schema fields are not shown.

Configuration and setup

How this tool was set up for the run and what the test needed in place. Each row is a fact from the run's records; a fact the records do not hold is left out, not guessed.

The source document had a clear no-report marker, and the schema required a repeated array. The job was to extract that empty set.

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 row says which 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 row 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.
