From Ingestion to Agents: How AI Teams Build on Document Intelligence — Adit Abraham, Reducto

Context

Document extraction needs to preserve what a page says, including its mistakes. A talk about Reducto's document-processing workflow describes a failure mode in which an image-and-text model rewrites a page and silently recalculates an incorrect total. That produces a different document, even if the arithmetic improves.

The workflow instead applies targeted corrections to recognized text, such as distinguishing a zero from the letter O. The intended benefit is to repair reading errors without inviting a fresh rewrite of the page. For an using extracted figures in later steps, this separates faithful transcription from the separate decision to question a document's contents.

Key takeaways · AI-distilled
  • Adit Abraham of Reducto argues that agents raise the cost of bad parsing: in a bad parse cost one answer, but in an agent the error compounds across every later step.
  • Reducto's agentic OCR applies -level corrections, such as a zero for an O, instead of having a VLM rewrite the page, because a VLM asked to rewrite OCR may helpfully 'fix' a total the human got wrong.
  • Simple tables go to markdown and complex ones to HTML, but Reducto also renders tables in natural language for retrieval, since models struggle to match a question like 'how did revenue change' to a blob of tags.
  • Per the talk, feeding parsed structure instead of raw PDFs lifted other frontier models past the newest one on a PDF-decision benchmark and cut reasoning tokens.
  • He says frontier models on their own tend to be precise but silently drop rows, while document services show the opposite tradeoff; agent harnesses with a code interpreter and repeated self-checks are pitched as getting both.
Terms in this piece · Glossary
  • AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
  • token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
  • RAG — Retrieval-augmented generation — fetching relevant documents first and pasting them into the model's context so it answers from your data instead of memory.
  • embedding — A list of numbers representing a piece of text's meaning, so that similar meanings end up numerically close and can be searched.
