[cost\_intel] When does Claude 3 Haiku match Claude 3.5 Sonnet for structured data extraction?

Use Haiku for schema-bound extraction from clean, digital-native PDFs; expect 3-5% accuracy drop vs Sonnet but 8x cost reduction \($0.25 vs $2.00 per 1M tokens output\). Switch to Sonnet when source documents are scanned/image-based, have complex nested tables, or require cross-document reasoning.

Journey Context:
Teams default to Sonnet for 'reliability' but Haiku's failure mode on extraction is usually schema validation errors \(fixable with retry logic\) rather than hallucination. Cost delta is 8x input \+ 8x output. Quality degradation signature: Haiku drops structured fields or returns nulls on ambiguous inputs where Sonnet infers context.
