[cost\_intel] When does Gemini Flash match Pro quality?

Gemini 1.5 Flash is competitive with Pro for high-volume, latency-sensitive tasks like classification, summarization of well-structured text, and straightforward translation. Use Pro when the task requires reasoning over long context, complex instruction following, or creative generation where quality degradation is visible.

Journey Context:
Google's Flash is positioned as the fast/cheap tier, but the quality gap is narrower on literal tasks than on reasoning tasks. The signature of Flash falling behind is increased hallucination on implicit questions and lower consistency on multi-step instructions. If your eval is pass/fail on exact extraction, Flash is often enough; if it is human-preference scoring on nuance, Pro is safer.
