Had a look at your job and you used our default mode (Accurate). This document work well with premium mode (see attached markdown, with the exception of a miss-classified chart as an image).

However the premium mode is more expensive as more compute is involved. Alternatively you can try to use our fast mode that will layout the text in an understandable way for LLM (but not extract the tables)

Thanks. I believe I would have to use the premium mode.
is there any reason why the model hallucinates in the default mode (Accurate) and not in other modes? Could playing with the parsing instructions (prompt) help in any way?
