Gemini 3.7 Flash API Pricing
Gemini 3.7 Flash shipped on August 14, 2026 for complex coding, agentic workflows and reliable multi-step execution. Google called it "our previous-generation Flash model" from September 2, 2026, when Gemini 3.8 Flash arrived on the identical rate card, and deprecated it on October 8, 2026: API requests to gemini-3.7-flash are now routed to Gemini 3.8 Flash, and the model is gone from Google's pricing page. Its last published card is the one Gemini 3.6 Flash and 3.8 Flash still carry: $0.75/M input, $3.75/M output and $0.075/M cached input through December 31, 2026, then $1.50 / $7.50 / $0.15 from January 1, 2027.

Gemini 3.7 Flash API cost calculator.
Live calculator pre-loaded with the Gemini 3.7 Flash rates in effect today — $0.75 input, $3.75 output, $0.075 cached. All three double on January 1, 2027, so a workload sized here costs twice as much from that date. Gemini 3.6 Flash prices identically, so switching between the two changes capability rather than the bill.

Estimate · gemini-tokenizer-estimate · ≈3.85 chars/token Auto-counts as you type
This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Gemini 3.7 Flash API pricing FAQ.
Gemini 3.7 Flash pricing questions, with the dated schedule kept separate from the rate in effect today.
Q · 01 How much does Gemini 3.7 Flash cost? +
Google last listed
gemini-3.7-flash at $0.75/M input, $3.75/M output including thinking tokens, and $0.075/M cached input. The model left the pricing page when Google deprecated it on October 8, 2026. Those rates were set to run through December 31, 2026; from January 1, 2027 the standard pricing was to be $1.50 / $7.50 / $0.15.Q · 02 Can I still use Gemini 3.7 Flash? +
Not as itself. Google deprecated
gemini-3.7-flash on October 8, 2026 and replaced it with Gemini 3.8 Flash. The endpoint is not shutting down, but API requests to it are routed automatically to gemini-3.8-flash, and the model can no longer be selected in Google AI Studio. Google asks developers to switch the model string to gemini-3.8-flash, and does not say which rate a routed request is billed at.Q · 03 Is Gemini 3.7 Flash more expensive than 3.6 Flash? +
No — they are priced identically, down to the cached rate and the January step-up. Google shipped 3.7 and moved 3.6 onto the same schedule on the same day. Under our standard blend both land at
$0.48/M effective, so the decision between them is a capability decision.Q · 04 What does the January 1, 2027 change mean for my bill? +
Every rate doubles. A workload costing $1,000 a month at today's rates costs $2,000 from that date with no change on your side. Cache storage moves too, from
$0.50 to $1.00 per 1M tokens per hour. Gemini 3.7 Flash itself left the pricing page on October 8, 2026; the same schedule still applies to Gemini 3.6 and 3.8 Flash, the model its requests are now routed to.Q · 05 What can Gemini 3.7 Flash take as input? +
Text, images, video, audio and PDF, returning text. The model page lists a
1,048,576-token input limit and a 65,536-token output limit, with context caching supported.Q · 06 Are thinking tokens billed separately? +
No — Google's output price is explicitly "including thinking tokens", so reasoning is billed at the same
$3.75/M as visible output. There is no separate reasoning rate to budget for, but heavy thinking still raises the output token count.
