Vision LLMs vs. OCR for PDF Q&A: OCR Still Wins on Cost and Accuracy

For complex PDF Q&A, vision LLMs are pricier and less accurate than OCR pipelines. Stick with OCR for better cost-performance and reliability.

[ KEY POINTS ]
  1. The native vision LLM approach was the most expensive at $0.2552/query and ranked 5th in accuracy (52.0%) out of six methods tested.
  2. Vision models underperformed on chart- and table-heavy pages, the very area they were expected to excel in. Premium OCR handled these better.
  3. The vision LLM had a 7% intrinsic failure rate that persisted after retries, while OCR-based pipelines showed 0% failure, indicating higher reliability.
