[cost\_intel] Using o3-mini for simple schema-following data extraction from PDFs

Use GPT-4o or Claude 3.5 Sonnet for structured data extraction with simple schemas \(invoice fields, name/address/phone\). Reserve o3-mini for extraction requiring complex inference \(implied values, multi-hop cross-references between tables, resolving ambiguous hand-written notes via context\). Cost difference: 10-30x.

Journey Context:
Extraction seems like it might need 'reasoning' to understand context. But most extraction is pattern matching \+ schema adherence. Instruct models are fine-tuned for tool use and JSON mode. Reasoning models add latency without accuracy gains on simple extraction \(name, date, amount\). The degradation signature: if task is 'read field X from document', cheap models work; if task is 'calculate field X based on Y and Z with business logic spanning 3 pages', use reasoning.
