How a few things work
Short write-ups on behaviours people ask about most.
Why it sometimes says "not found"
If the documents you've selected don't contain the answer, the platform tells you so. It doesn't reach for general knowledge and dress it up as your data.
This costs us some answer rate, and we've made that trade on purpose. In finance, a confident wrong number does more damage than an honest gap.
What it does with charts and scanned pages
A vision model writes a short description of each chart it finds in a PDF, Word or PowerPoint file, and of any image you upload. The description is labelled as machine-written and can be cited.
It is never treated as a figure. The model is told not to estimate values from the height of a bar, so a number only reaches an answer if it's printed somewhere.
When two documents disagree
Companies restate numbers. In one of our test sets, a prior-year operating profit is 241.7 in the report for that year and 219.4 in the next year's report, which restated it.
Conflicts like this are what the platform's contradiction check is for. It flags the mismatch and points to both sources, so you can decide which figure the question needs.
