Where Upstage AI failed

2 of 5 graded scenarios. Open a Result to see the conversation and the evidence.

Figures & Charts

A document with a data chart

Upstage AI failed this PDF-chart scenario: the page-3 chart was not preserved as an image with its title. The Markdown shows a placeholder image, 'Chart Type: bar', and a wrong value table; the surrounding prose and page-2 Figure 1 caption remain.

Text Fidelity

An ordinary digital text document

Upstage AI did not keep ordinary digital text unchanged. At one page break, it joined a running header to a continuation of the body text; the other five breaks stayed clean.

What happened

Upstage AI kept footnotes out of the body flow and attached them to their references in this test. The source PDF’s thirteen notes all appear in the Markdown, set as separate blocks after the relevant page body. Each note keeps its leading number, and the matching reference digit remains in the body text. One reference digit has a space before it.

1 of 1 test case passed
What happened

Upstage AI recovered the text from the scanned page. The page had no text layer, and the Markdown returned every printed block correctly; the closing words were styled as a heading and the results came back as a pipe table.

A document mixing digital and scanned pages
1 Pass0 Fail0 Not gradable
1 of 1 test case passed
What happened

Upstage AI processed the scanned page inside the mixed PDF instead of skipping it. The scanned worksheet appears in place between the two digital pages, and the service reports all three pages processed with OCR on; the scanned page also returns the most elements, with only small spacing and punctuation changes.

Reading these Results

Published evidence and test coverage answer different questions.

Publication availability

Which scenarios have a Result?

A published Result is public evidence for this tool on one scenario. “No published result” does not say whether testing has taken place.

Test coverage

What does each Result cover?

Assessed includes Pass, Fail and Not gradable. Gradable includes Pass and Fail. Both use the pinned test count in that published Result.

Scenario scope

Out of 12 scenarios

The summary counts each of the 12 scenarios once. A scenario fails when any of its published test cases failed. “No published Result yet” means nothing is public for that scenario; it does not say whether Upstage AI was tested on it.
