Worth knowingIntroductory rate through 31 Dec 2026

A typical 1,200-in / 400-out token request costs about $0.0024, or roughly $2.40 per 1,000 requests.

Gemini 3.8 Flash runs $0.75 per million input tokens and $3.75 per million output. The important detail is not the number, it is the footnote: Google lists this as an introductory rate running through 31 December 2026. The same applies to Gemini 3.7 Flash and 3.6 Flash, which carry identical pricing and the same end date.

That makes Flash the one tier on this site where the price you see is guaranteed to change. If you are building a 2027 budget on today's Flash rate, you are budgeting on a number with an expiry attached. Either model the post-January figure now, or pin high-volume workloads to a tier whose price is not time-boxed. This is the kind of thing that is trivially cheap to plan for in advance and genuinely painful to discover in a January invoice.

Best for
  • High-volume classification, extraction and summarisation at the lowest current rate
  • Workloads you can move if the January price change makes another tier cheaper
  • Teams who will actually revisit the budget rather than set it and forget it
