[cost\_intel] For structured data extraction from unstructured text, when do reasoning models beat instruct models?

Use GPT-4o for simple entity/relationship extraction; use o1 only when extraction requires complex coreference resolution across >1000 tokens, implicit logical deduction, or multi-hop reasoning to identify entities.

Journey Context:
Standard NER \(Named Entity Recognition\) and schema-filling tasks are pattern-matching problems where GPT-4o achieves >95% F1 score. Reasoning models add cost and latency without accuracy gains for explicit entities. However, when extraction requires 'reading between the lines'—for example, determining that 'the former CEO' refers to a specific person mentioned three paragraphs earlier, or inferring a contractual party from indirect descriptions—reasoning models' ability to maintain and reason over long context chains provides measurable gains. The threshold is generally: if a human annotator needs to pause and think to resolve the reference, use o1; if it's a 'find and label' task, use 4o.
