Gemini 3.8 Flash
price and who can get it
Google shipped Gemini 3.8 Flash and 3.8 Flash Cyber on 2026-09-02. The published entry price is $0.75 per 1M input tokens and $3.75 per 1M output, an introductory rate expiring 2026-12-31, after which it becomes $1.50 / $7.50. The official model page now lists 1M context and 64k max output; on 2026-10-08, 3.7 Flash was deprecated and requests were automatically routed to 3.8 Flash. The Cyber variant stays limited to trusted defenders via Fairwind.

Four official numbers
Input / output per 1M tokens
The official blog calls this an introductory price, not the standing rate.
Last day of the intro price
From the next day the official rate becomes $1.50 / $7.50. Any budget model for this model has to include that date.
The 2027 increase
Input $0.75→$1.50 and output $3.75→$7.50 — both exactly double. That is published, not inferred.
The only route to the Cyber variant
3.8 Flash Cyber is limited to trusted defenders through the Fairwind Program; general developers cannot get it.
Two models, two very different availabilities
This launch is a pair. Gemini 3.8 Flash is for general developers, reachable through Google AI Studio, Android Studio and Google Antigravity, with enterprises going through Gemini Enterprise and consumers through Google AI Pro and Ultra subscriptions. 3.8 Flash Cyber is a restricted security-oriented build that the announcement limits to trusted defenders via the Fairwind Program. When you see capability claims about "3.8 Flash", check which one is meant — their availability is not the same. The 2026-10-08 release notes add that 3.7 Flash is deprecated and API requests are automatically routed to 3.8 Flash, while 3.5 Flash is routed to 3.6 Flash. The official model page also lists 1M context and 64k max output for 3.8 Flash.
Beyond price: 3.7 Flash was deprecated on 2026-10-08
The launch post gave $0.75 / $3.75 and stated an "introductory price expires on December 31, 2026", with $1.50 / $7.50. A post-2027 cost model at today's rate underestimates by half. The 2026-10-08 release notes add that gemini-3.7-flash is deprecated and API requests are automatically routed to gemini-3.8-flash, so update the model string to gemini-3.8-flash. Most secondary coverage quotes only the first half.
How the Flash line has moved
Google ships a batch of Gemini 3.6 Flash models. The same official post states that Gemini 3.5 Pro is still testing with partners and will be made broadly available as soon as it is ready, and announces that the most ambitious pre-training run yet has begun, for Gemini 4.
Gemini 3.8 Flash and 3.8 Flash Cyber ship. Entry price $0.75 / $3.75 with the introductory rate expiring 2026-12-31. The Cyber variant is limited to the Fairwind Program.
2026-10-08 release notes: 3.7 Flash is deprecated and automatically routed to 3.8 Flash, while 3.5 Flash is routed to 3.6 Flash; the official model page already listed 1M context and 64k max output for 3.8 Flash. As of 2026-10-20, the status of 3.5 Pro and Gemini 4 was not updated in that note.
What the announcement says and does not say
✅ In the official announcement
Release date 2026-09-02; two models, Gemini 3.8 Flash and 3.8 Flash Cyber; pricing $0.75 / $3.75 per 1M tokens with the introductory rate expiring 2026-12-31 and $1.50 / $7.50 after; distribution through Google AI Studio, Android Studio, Google Antigravity, Gemini Enterprise and Google AI Pro / Ultra; and the Cyber variant limited to trusted defenders through the Fairwind Program. 2026-10-08: 3.7 Flash deprecated and routed to 3.8 Flash; the official model page lists 3.8 Flash at 1M context, 64k max output and thinking levels low / medium / high.
⚠️ What this announcement does not give
The launch announcement gave no context window or API model id. The official model page now lists gemini-3.8-flash with 1M context and 64k max output. Gemini 4 Argon reached GA on 2026-10-13; 3.5 Pro is not on the official model list as of 2026-10-20.
Worth switching from the previous generation?
3.8 Flash
The newest generation at an official entry price of $0.75 / $3.75 — but remember that is the rate through year end. Suits teams running volume now whose budget model can absorb the 2027 increase.
Still on 3.7 / 3.6 Flash
3.7 Flash was deprecated on 2026-10-08 and requests are routed to 3.8 Flash automatically; 3.6 Flash remains supported. If your workflow is tuned on the older model, compare it on the same real requests first. The price advantage narrows by half after 2026-12-31.
How to decide whether to migrate
Three steps. First, put the post-2027-01-01 rate into your annual model rather than estimating on $0.75 / $3.75. Second, confirm you mean 3.8 Flash and not the Cyber variant, which general developers cannot obtain. Third, benchmark on your own real requests — differences within the Flash line show up per task, and a leaderboard position does not change your bill. If you are still on 3.7 Flash, requests have been automatically routed to 3.8 Flash since 2026-10-08; change the model string to gemini-3.8-flash and re-check parameters against the 1M context and 64k output ceiling.
On QCode
QCode does not currently offer the Gemini series. Please use Claude, GPT or Chinese models instead (e.g. claude-sonnet-5-5, gpt-6.1-sol, glm-5.3). Not ready for a monthly plan? Pay-as-you-go Packs start at $4 for a one-time quota you use within 7 days; with an active Personal Plan you cannot buy a pack, so buy a booster pack when the plan quota is short.
Frequently asked questions
What does Gemini 3.8 Flash cost?
The official announcement gives $0.75 per 1M input tokens and $3.75 per 1M output, explicitly an introductory rate through 2026-12-31. From 2027-01-01 it becomes $1.50 / $7.50 per 1M tokens, so both double. The official model page also lists 1M context and 64k max output.
Can I use 3.8 Flash Cyber?
Most likely not. The announcement limits it to trusted defenders through the Fairwind Program; it is not a tier a general developer can self-serve.
What is the context window?
The official model page lists 3.8 Flash with an input limit of 1,048,576 tokens and an output limit of 65,536 tokens (1M context, 64k output). The 2026-09-02 launch announcement itself does not give a figure; check Google's official model documentation for the exact value.
What is the status of Gemini 3.5 Pro and Gemini 4?
This 3.8 Flash announcement does not mention them. What can be checked on Google's official pages: the 2026-07-21 official post said 3.5 Pro was testing with partners and would be broadly available when ready; Gemini 4 Argon reached GA on 2026-10-13; 3.5 Pro is still not on the official model page as of 2026-10-20.
Can I call Gemini on QCode?
No. QCode does not currently offer the Gemini series. Please use Claude, GPT or Chinese models instead (e.g. claude-sonnet-5-5, gpt-6.1-sol, glm-5.3).
So what is this page for?
Two things. It pins down the expiry of the introductory price and the actual 2027 rate so a cross-year budget is not understated by half, and it separates 3.8 Flash from the Cyber variant that only goes to trusted defenders, so you do not choose based on capabilities you cannot access.

One key for the vendors that are actually callable
Claude, GPT-6 Astra, GPT-5.6 and Chinese models share one QCode key and quota—switching is just the model id. Billed per token; per-model rates are listed on /models.
Gemini 3.5 Flash guide
As of 2026-08-30 the official model page still lists stable id gemini-3.5-flash: 1,048,576 input, 65,536 output, standard $1.50 / $9.00 per million tokens (output includes thinking). Default thinking level is medium. QCode does not currently offer the Gemini series.

Gemini 3.5 Flash-Lite guide
As of 2026-08-30 the official pricing table lists Standard $0.30 input / $2.50 output per million tokens (output includes thinking). Stable id gemini-3.5-flash-lite, 1,048,576 input, 65,536 output. QCode does not currently offer the Gemini series.

Gemini 3.6 Flash Guide
Google's Flash workhorse update: stronger coding and multimodal work, at the launch price of $1.50 input / $7.50 output per 1M tokens (Paid tier, thinking tokens included in output).
Gemini 3.6 Flash is generally available as model id gemini-3.6-flash. The same July 21 announcement also shipped 3.5 Flash-Lite and 3.5 Flash Cyber as separate models — do not mix their specs with 3.6 Flash.
3.7 vs 3.6 Flash
Official Standard intro is $0.75 / $3.75 on both through 31 Dec 2026. 3.7 sells a coding/agent jump, not a discount. QCode does not currently offer the Gemini series.
Two adjacent Flash SKUs. Context in the same 1,048,576 / 65,536 class. 3.7 is pitched at first-pass coding, long-horizon agents, documents and automation. 3.6 is still a live workhorse, not a retired id.
Both ids are in Google’s docs. Intro Standard price matches.
3.7 Flash vs Sonnet 5
The DeepMind model card / launch table lists Claude Sonnet 5 at $2 in / $10 out and prints vendor figures (DeepSWE v1.1: 3.7 at 65.3% vs Sonnet 5 at 53.8%; FrontierCode 1.1 Main: 43.6% vs 42.7%). Those rows are Google’s table, not a rerun on this site, not an independent rank. Sonnet 5 at $2 / $10 matches what Anthropic confirmed as standard on 10 Aug 2026.
