Gemini Flash Pricing: Every Generation From 2.0 to 3.8
Google sells more generations of Gemini Flash at once than most makers sell models. Its pricing page, read on October 13, 2026, prices seven Flash and Flash-Lite models, two of them deprecated; its deprecations page accounts for four more that no longer appear there. This post puts every one of them in the same table, with the figures as Google prints them and the status each page gives, works out what one month of the same workload costs on each, and says what happens to the people still on the older ones. It compares prices only; Google’s pages give no reason for them.
Every Flash and Flash-Lite, as Google prices them
Per million tokens, standard paid tier, text input. “Last read” means Google no longer prints the model on its pricing page and the figures are the last ones this site read there.
| Model | Input | Output | Cached input | Context | Status | Shutdown | Read |
|---|---|---|---|---|---|---|---|
| Gemini 3.8 Flash | $0.75 | $3.75 | $0.075 | 1M | current, promotional price | none announced | October 13, 2026 |
| Gemini 3.7 Flash | $0.75 | $3.75 | $0.075 | 1M | deprecated, routed to 3.8 Flash | N/A | last read October 5, 2026 |
| Gemini 3.6 Flash | $0.75 | $3.75 | $0.075 | 1M | current, promotional price | none announced | October 13, 2026 |
| Gemini 3.5 Flash | $1.50 | $9.00 | $0.15 | 1M | deprecated, routed to 3.6 Flash | N/A | last read October 5, 2026 |
| Gemini 3.5 Flash-Lite | $0.30 | $2.50 | $0.03 | 1M | current | none announced | October 13, 2026 |
| Gemini 3.1 Flash-Lite | $0.25 | $1.50 | $0.025 | 1M | deprecated | May 7, 2027 | October 13, 2026 |
| Gemini 3 Flash Preview | $0.50 | $3.00 | $0.05 | not recorded | deprecated | none announced | October 13, 2026 |
| Gemini 2.5 Flash | $0.30 | $2.50 | $0.03 | 1M | current, limited access | none announced | October 13, 2026 |
| Gemini 2.5 Flash-Lite | $0.10 | $0.40 | $0.01 | 1M | current, limited access | none announced | October 13, 2026 |
| Gemini 2.0 Flash | $0.15 | $0.60 | $0.0375 | not recorded | retired | June 1, 2026 | September 3, 2026 |
| Gemini 2.0 Flash-Lite | $0.075 | $0.30 | $0.01875 | not recorded | retired | June 1, 2026 | September 3, 2026 |
“1M” is the 1,048,576-token context window in this site’s dataset. Audio input costs more where Google prices it apart: $1.00 on 2.5 Flash, $0.30 on 2.5 Flash-Lite, $0.50 on 3.1 Flash-Lite. The two 2.0 rows are kept for reference; they stopped answering on June 1, 2026.
Gemini Omni Flash carries the Flash name but not the job. Google’s model page, read on September 30, 2026, gives its output as “Video” only, so it sits outside this site’s table of text models: $1.50 input, “$9.00 (text)” for output including thinking tokens and “$17.50 (video)”. Its preview endpoint shuts down on October 22, 2026, replaced by gemini-omni-1.1-flash.
The 3.8 and 3.6 Flash promotion, and January 1, 2027
The two current Flash models are on a promotion with a printed end. Google’s block for Gemini 3.8 Flash reads: “Input price | Free of charge | $0.75 through December 31, 2026. | $1.50 starting January 1, 2027. | Output price (including thinking tokens) | Free of charge | $3.75 through December 31, 2026. | $7.50 starting January 1, 2027.” The cache follows, “$0.075 through December 31, 2026. | $0.15 starting January 1, 2027.”, and so does cache storage, from $0.50 to $1.00 per million tokens per hour. Gemini 3.6 Flash prints the same six figures.
On January 1, 2027 every one of those prices doubles. This site has recorded the change in advance on its price-changes page as an announced provider increase. Google’s page gives the dates and the figures, nothing about why.
One month on each
The same workload on every model: 100 million input tokens and 20 million output tokens in a month, no cache, standard prices.
| Model | Input | Output | Month | Status |
|---|---|---|---|---|
| Gemini 2.5 Flash-Lite | $10.00 | $8.00 | $18.00 | current, limited access |
| Gemini 3.1 Flash-Lite | $25.00 | $30.00 | $55.00 | deprecated, shuts down May 7, 2027 |
| Gemini 3.5 Flash-Lite | $30.00 | $50.00 | $80.00 | current |
| Gemini 2.5 Flash | $30.00 | $50.00 | $80.00 | current, limited access |
| Gemini 3 Flash Preview | $50.00 | $60.00 | $110.00 | deprecated |
| Gemini 3.6 Flash | $75.00 | $75.00 | $150.00 | current, promotional price |
| Gemini 3.8 Flash | $75.00 | $75.00 | $150.00 | current, promotional price |
| Gemini 3.6 or 3.8 Flash from January 1, 2027 | $150.00 | $150.00 | $300.00 | list price |
| Gemini 3.7 Flash, last read | $75.00 | $75.00 | $150.00 | deprecated |
| Gemini 3.5 Flash, last read | $150.00 | $180.00 | $330.00 | deprecated |
Among current models the range is $18.00 to $150.00 a month, and the cheapest is the oldest. Gemini 2.5 Flash-Lite costs less than a third of the cheapest 3.x model, Gemini 3.1 Flash-Lite at $55.00. Gemini 2.5 Flash and Gemini 3.5 Flash-Lite cost exactly the same, $0.30, $2.50 and $0.03, so the newer Lite and the older full Flash meet at $80.00.
Cheapest, and cheapest you can start on
The 2.5 models come with a condition. On Gemini 2.5 Flash-Lite’s model page, read on October 1, 2026, and in the 2.5 block of the deprecations page read on October 13, Google writes: “To ensure reliable performance for everyone, we are limiting access to the 2.5 models to users who have actively used them in the past. These models are not deprecated and will continue to be served until further notice through the API. For any new projects, use our latest models: 3.5 Flash-Lite or 3.8 Flash.”
So for a project already on 2.5 Flash-Lite, $18.00 is the cheapest Flash month on offer. For a new project, the two models Google names cost $80.00 (3.5 Flash-Lite) and $150.00 (3.8 Flash, promotional) for this workload, and 3.8 Flash goes to $300.00 on January 1, 2027.
If you are on a deprecated Flash
Google’s deprecations page, read on October 13, 2026, gives a different fate to each:
- Gemini 3.1 Flash-Lite has a date: “gemini-3.1-flash-lite | May 7, 2026 | May 7, 2027 | gemini-3.5-flash-lite”. Moving to the named replacement takes this month from $55.00 to $80.00, 45% more, because 3.5 Flash-Lite costs more on both input and output.
- Gemini 3 Flash Preview has none: “No shutdown date announced”, with gemini-3.6-flash as the replacement. That move goes from $110.00 to $150.00 now and to $300.00 from January 1, 2027.
- Gemini 3.5 Flash and Gemini 3.7 Flash are not shutting down in the usual sense. Their rows read “N/A” for shutdown and the page says the endpoint “is not shutting down and automatically routes API requests to” gemini-3.6-flash and gemini-3.8-flash respectively. The pages read for this post do not say which price a routed request is billed at, and this post does not assume one.
- Gemini 2.0 Flash and 2.0 Flash-Lite were shut down on June 1, 2026, with gemini-3.6-flash and gemini-3.1-flash-lite named as their replacements. The second of those is now deprecated itself.
All of these dates and replacements are also on this site’s deprecations page.
How this was read
Every price, status and sentence above comes from Google’s Gemini API pricing page and deprecations page, downloaded on October 13, 2026, and matches this site’s dataset rows for each model, verified on October 12 or 13, except Gemini 3.5 and 3.7 Flash, whose last prices were read on October 5, 2026, and the two 2.0 rows, read on September 3, 2026. While preparing this post, the Gemini 3 Flash Preview row was found to lack an output price that the Gemini API page publishes; the row was corrected on October 13 and the omission is recorded on the price-changes page. Prices are standard paid-tier list prices in US dollars, without Batch, Flex or Priority. All of Google’s current prices are on the Google pricing page of this site.
