[cost\_intel] When does Gemini 1.5 Flash match GPT-4o on visual tasks versus requiring the frontier model?

Flash matches GPT-4o on single-page document OCR and chart reading within 3% accuracy at 1/20th the cost, but fails on multi-panel layouts requiring cross-image spatial reasoning or fine-grained visual relationships such as 'is object A left of object B in diagram C?'.

Journey Context:
Teams often default to GPT-4V for all vision tasks due to early benchmark leaderboards. Flash's 1-million-token context and inference speed actually make it superior for bulk document processing pipelines. The quality cliff appears at reasoning depth: Flash hallucinates spatial relationships and struggles with comparative visual questions across multiple images—tasks requiring maintenance of visual state across turns. Reserve GPT-4o for architectural diagrams, multi-panel medical imaging, or any task requiring precise spatial localization; use Flash for receipts, invoices, and single-page text extraction.
