[cost\_intel] Using GPT-4o for high-resolution document OCR when Gemini 1.5 Flash achieves equivalent character-level accuracy at 1/15th cost

Use Gemini 1.5 Flash for OCR on scanned documents <20 pages; costs $0.075 per 1M tokens input vs GPT-4o's $2.50, with equivalent accuracy on printed text but failure on handwritten cursive

Journey Context:
GPT-4o's vision capabilities are overkill for standard document digitization. Gemini Flash offers massive context windows $1M tokens$ and extremely low pricing for image understanding. It matches GPT-4o on printed text, tables, and forms. However, it hallucinates or fails on handwritten medical notes or complex cursive. The cost delta $30x$ makes Flash the default for document processing pipelines, with GPT-4o reserved for failed edge cases.
