Report #63084

[cost\_intel] At what image resolution/complexity does Gemini 1.5 Flash fail vs Pro for structured visual extraction \(charts, tables\)?

Use Gemini 1.5 Flash for visual tasks with <3MB images, <5 distinct objects/regions, and text >8pt font; migrate to Pro when extracting from dense infographics \(>10 overlapping elements\) or when OCR accuracy on low-contrast text \(<12pt\) is critical—Flash achieves ~85% accuracy vs Pro's 98% on dense layouts.

Journey Context:
Flash is 20x cheaper \($0.075 vs $1.25 per 1M tokens for images\) and 2-3x faster, but tokenizes images with fewer tiles/detail. On sparse screenshots \(single form\), Flash matches Pro. On dense academic papers with 2-column layout, sidebars, and footnotes, Flash hallucinates structure \(merges columns, misses footnotes\) while Pro maintains fidelity. Quality degradation signature: Flash treats fine-grained spatial relationships as 'suggestions' rather than constraints. Cost trap: Processing 1000 dense pages with Flash at 85% accuracy requires 150 re-runs with Pro to fix errors, costing more than using Pro initially.
