Model board / Gemini 3.8 Flash

Verified 2026-09-03 against the pages listed below. Prices are USD per 1M tokens, list rate — no committed-use, enterprise or volume discount.

introductory through 2026-12-31; the pricing page states it rises to $1.50/$7.50 on 2027-01-01. Cache storage $0.50 per 1M/hr, doubling to $1.00 on the same date. Identical to Gemini 3.7 Flash in every column

1M window and 64K max output, both stated on the latest-model page

cached input at 10% of base; explicit caches also bill hourly storage

Watch out

Arrives at exactly Gemini 3.7 Flash's price, so the upgrade is free, but it inherits the same clock: $0.75/$3.75 is introductory and doubles on 2027-01-01. Thinking is tunable across low, medium and high, and medium is the default — a cost model built on the low setting will not match the bill

What we would use it for

The default Flash pick — 3.7's price with a newer model behind it

What this has cost, week by week

Output price at each refresh since 2026-09-03. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.

Nothing has moved since we started tracking it.
