Model overview

Gemini 3.1 Flash-Lite 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.

$6.25

Planning estimates using the listed token rates, with no caching, retries, batch discount, or tool fees. These examples assume text usage; images, audio, video, and higher rate tiers can change your bill. Each agent step is a separate request.

With 50% of input tokens served from cache, the short-conversation example costs $5.13 per 10,000 requests, compared with $6.25 without cache hits. Cache-write fees are excluded.

How billing works

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

Separate input from output

For Gemini 3.1 Flash-Lite, multiply input and output token counts by their respective rates, then divide by one million. Conversation history and retrieved context contribute to input usage each time they are sent.

Cache hits have their own rate

The listed cached-input price is $0.025 per million tokens. Reusing a prompt does not automatically qualify: use the provider's reported cached-token count, and account for any cache-write or storage charges.

Check discounts and rate tiers

Eligible batch requests use 50% of the standard token rate in this listing. Batch work is asynchronous; check supported endpoints and turnaround times. 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.
