Model overview

Understand the model before estimating your workload.

Use the model ID gemini-3.5-flash through the provider's direct API. The prices and limits on this page apply to that specific listing, with source data checked on 2026-10-12.

Gemini 3.5 Flash has a published context window of 1,048,576 tokens. A separate maximum output limit is not recorded for this channel. Budget context space for your prompt, conversation history, retrieved material, and the response. Context capacity and output limits are different; your input and response must fit within the request limits. A larger window does not make those tokens free.

How billing works

The details that turn a token rate into an actual bill.

Use the published billing unit

This model uses a billing unit that is not yet recorded. Do not substitute a text-token estimate for image, audio, video, or document charges.

A missing rate is not free usage

If a price, discount, or limit is marked not published, confirm it with the provider before estimating spend. The calculator does not invent a separate cache discount when no cached-input rate is available.

Check discounts and rate tiers

No batch multiplier is applied to the examples on this page. Check the pricing source before assuming an asynchronous job receives a discount. Review the provider's pricing terms for workload-specific conditions.

Account for the complete workflow

Retries, follow-up calls, and agent tool loops increase request counts. Search, storage, and other tool charges can be billed separately from model inference. Use actual API usage logs to calibrate a budget before scaling traffic.
