Gemini Token API Price Comparison: Notes

  • Prices below are Paid tier Standard processing in USD per 1M tokens; Free tier in AI Studio offers free input/output on select models (content may improve products)—upgrade to Paid for production.
  • Gemini 3.1 Pro and 2.5 Pro use tiered pricing at ≤200K vs >200K prompt tokens (e.g. 3.1 Pro Standard: $2/$12 vs $4/$18 per MTok).
  • Batch API is ~50% off input/output; context caching adds storage fees (typically $0.50–$4.50 per 1M tokens/hour, model-dependent).
  • Image generation (3.1 Flash Image, etc.) and Live API audio/video use different billing from plain text chat—estimate per use case before integration.
