Google Gemini Pricing

Gemini's rate card is the most aggressive at the budget tier, with Flash-Lite at $0.10/1M input. Pricing tiers shift above 128K context — long-context workloads need a different cost model.

Current per-token rates

Gemini 2.5 Pro: $1.25/$10 (≤200K), $2.50/$15 (>200K). Gemini 2.5 Flash: $0.30/$2.50. Flash-Lite: $0.10/$0.40.

Long-context pricing tier

Pro doubles in price above 200K input tokens. Forecast with the higher rate if average prompts exceed 100K — a single long doc can flip the tier.

Context caching

Storage billed per hour per 1M tokens (~$1/hr at Pro tier). Cached reads at ~25% of standard. Worth it when the same context is reused 5+ times per hour.

Worked cost example

Doc-Q&A: 50K context + 300 output, 20K calls/month. Pro uncached ≈ $1,310. Flash ≈ $315. Flash-Lite ≈ $102.

When each tier fits

Pro: reasoning, multimodal, long-doc analysis. Flash: default for production. Flash-Lite: classification, extraction, and bulk pipelines where Flash overshoots on capability.
