AI analysis of financial documents: accuracy issues and solutions

This title was summarized by AI from the post below.

ChatGPT writes a better first draft analysis than most analysts. It also can't reliably extract numbers from a scanned PDF. When deal teams see AI-generated analysis with incorrect figures, they blame the model. But trace the error back, and you'll find it's likely that it originated during document processing, before the model ever started analyzing. We've been testing frontier models on real financial documents and found a consistent pattern: the analysis reads well, the confidence scores look fine, but the underlying numbers can ultimately be wrong. Models drop minus signs from income statements, misalign table columns, and introduce digit-level errors in extraction. This happens because general-purpose vision processing optimizes for understanding concepts, not preserving pixel-level precision. Features that matter in finance like decimal points, negative signs, subscripts exist at resolutions these systems sacrifice for efficiency. It's like reading through frosted glass: you can see enough to reconstruct something plausible, but not enough to guarantee accuracy. Standard AI benchmarks don't catch this because they test comprehension using clean documents. Real workflows involve scanned PDFs, compressed filings, and hybrid image-text formats where these failures show up reliably. We've developed approaches that significantly reduce these errors and are continually optimizing. The takeaway here is AI's reliability problem in finance isn't mainly about reasoning. It's about whether models can accurately pull numbers from real documents in the first place. Bad extraction creates bad outputs, which lead to bad decisions. By the time you're questioning the AI's conclusions, the damage already happened upstream.
