Which to pick

Pick **Claude Haiku 4.5** when you want Anthropic's tone, refusal behaviour, and tool-use shape across a team that already runs Sonnet and Opus. The 200k context fits most chat patterns and the $0.80 in / $4 out per Mtok pricing is competitive on output even if Gemini Flash undercuts it on input. Pick **Gemini 2.5 Flash** for very high-volume or long-context bulk work — extracting from huge corpora, batch summarisation, classification at the pennies-per-Mtok end of the market. At $0.15 in / $0.60 out per Mtok plus a 1M-token window, it's roughly 5x cheaper on input and 5x larger context than Haiku, which is the whole reason to prefer it.
