[cost\_intel] Choosing between Claude 3.5 Sonnet and GPT-4o for text extraction from images

Use Claude 3.5 Sonnet for printed text/PDF screenshots \(60% cheaper, equivalent accuracy\); reserve GPT-4o for handwritten text, low-contrast scans, or complex spatial layouts \(tables with merged cells\)

Journey Context:
Claude 3.5 Sonnet costs $3/1M input \+ $15/1M output vs GPT-4o at $5/1M \+ $15/1M. For vision, both charge per image tile. On printed text benchmarks \(TextVQA\), Sonnet achieves 85.5% vs GPT-4o 86.2%, within noise margin. However, on handwritten documents \(IAM dataset\), Sonnet drops to 65% while GPT-4o maintains 82%. GPT-4o also handles complex tables with merged cells significantly better due to superior spatial reasoning. The cost difference is 40-60% depending on image size. A common error is using GPT-4o for all document processing, incurring 2x costs for clean printed PDFs where Sonnet suffices. Another failure mode: using Sonnet for historical manuscript digitization, requiring expensive human-in-the-loop correction that exceeds GPT-4o's premium.
