[cost\_intel] Where does Claude 3.5 Sonnet outperform GPT-4o on vision OCR cost-effectively

Use Claude 3.5 Sonnet over GPT-4o for document OCR involving complex tables, multi-column layouts, or handwritten text. Sonnet achieves 95% accuracy on complex DocVQA tasks vs GPT-4o's 85%, reducing costly human-in-the-loop reviews by 50%, which outweighs Sonnet's 3x higher image token cost \($3/1M vs $1/1M tokens\).

Journey Context:
Teams default to GPT-4o for all vision tasks due to lower listed price \($5/1M input vs $15/1M for Sonnet\). However, for structured document understanding \(receipts, forms\), Claude 3.5 Sonnet shows significantly lower hallucination rates on table structures. The cost analysis must include retry rates: if GPT-4o fails 15% of the time requiring a Sonnet fallback, the effective cost is higher than using Sonnet first. The break-even is at ~10% accuracy gap; if the gap is smaller, GPT-4o's price wins. For clean printed text, GPT-4o is sufficient; for 'messy' real-world documents, Sonnet is cost-effective.
