How the Gemini API is priced

Google bills Gemini API calls per token, at three rates per million tokens: input, cached input and output. Output costs several times input on every Gemini model, and cached input costs a tenth of input or less. A request costs its tokens times the rates of the model it named; there is no seat or plan price.

Every Gemini model

11 Gemini models. Each row shows our price and Google's list price.

Two requests, worked

A chat turn of 2,000 input and 500 output tokens, and a long-document request of 50,000 input and 2,000 output. Both sizes are assumptions; nothing is counted at the cached rate.

Input tokens times the input rate plus output tokens times the output rate, per million.

Gemini 4 Argon: $0.60 in and $3.00 out here, against $2.00 and $10.00 at list, 70% under on input and 70% on output.

Gemini 3.1 Pro Preview: $1.20 in and $7.20 out here, against $2.00 and $12.00 at list, 40% under on input and 40% on output.

Gemini 3.8 Flash: $0.45 in and $2.25 out here, against $0.75 and $3.75 at list, 40% under on input and 40% on output.

Cached input

When a request repeats a prefix the API has seen, such as a long system prompt or a document, the response reports those tokens as cached and they bill at the cached rate in the first table. A model with no cached rate bills them at its input rate.

Calling it

Point the SDK at our base URL with your key. Every Gemini id in the table works with the same two values.

openai.py
from openai import OpenAI

client = OpenAI(
    base_url="https://api.uplinkswitch.com/v1",
    api_key="sk-uplink-live-...",
)

completion = client.chat.completions.create(
    model="gemini-4-argon",
    messages=[{"role": "user", "content": "Summarize this in one line."}],
)
print(completion.choices[0].message.content)

Questions

Is there a subscription? No. Credit is prepaid from $10, and each top-up locks your prices for 30 days. New accounts start with $1 free.

Which Gemini model should I use? The cheapest one that does the task. Flash Lite for short high-volume work, Flash for most chat and coding, Pro or Gemini 4 Argon where the harder answer is worth the price. Run the same prompt on each and compare.

Where is the full price list? On the Gemini pricing page, and every other model on the Models page. To see what your own usage would cost, re-price an export on the savings page.
