[cost\_intel] Using GPT-4V or Claude 3.5 Sonnet for OCR or text extraction from images instead of specialized OCR

For text-heavy images or PDFs, use dedicated OCR \(Tesseract, AWS Textract, or Gemini Flash's native OCR\) before LLM processing. Only use multimodal LLMs for visual reasoning \(charts, diagrams, ambiguous layouts\). Cost diff: OCR is $0.001-0.002 per page vs GPT-4V at $0.005-0.01 per page \(depending on resolution/tiles\), and OCR avoids token bloat from image encoding.

Journey Context:
Developers often pipe screenshots/PDFs directly to GPT-4V for 'extraction,' but this tokenizes the image at high resolution \(e.g., 1024x1024 low-res = 765 tokens, high-res = multiple 512x512 tiles at 255 tokens each\). For pure text, OCR is 100-1000x cheaper per page and often more accurate \(no hallucination of text content\). Multimodal LLMs are only cost-effective when layout, visual context, or reasoning is required \(e.g., 'extract the value in the red box' or 'interpret this scatter plot'\).
