Not only is the summary kinda light or missing the deeper points, the LLM did not "break down" the plot by "reading" the provided PDF. House of Leaves is impossible to fucking parse correctly as a PDF, the text is all over the place, visually placed in very complex ways, you have a whole labyrinth chapter where you have to follow footnotes across multiple pages with the text being difficult to find and follow, anything "reading" the PDF in the regular order of characters would have no fucking clue.
As always, there is no intelligence or any breaking down, the only reason the LLM is able to provide the summary is because it was trained on a dataset that included summaries and reviews of House of Leaves, and it simply detected the PDF was House of Leaves.
The LLM is, YET AGAIN, just regurgitating things that are already written elsewhere, nothing is created, it's all obfuscation of labour.
