Ids ending in :free and rows with a zero price in and out.

| Model id | Context (tokens) | Input, USD per 1M | Output, USD per 1M |
|---|---|---|---|
| google/gemma-4-26b-a4b-it:free | 262,144 | $0.00 | $0.00 |
| google/gemma-4-31b-it:free | 262,144 | $0.00 | $0.00 |

## Read the list yourself

The same OpenRouter model list is readable through looot with one free call: looot run openrouter-models --input '{}'

## Which AI models can I call for free?

In this list, google/gemma-4-26b-a4b-it:free and google/gemma-4-31b-it:free. Both are zero-price variants on the OpenRouter model list. This page lists price only; read the provider's own limits before you build on a free variant.

## Where do these prices come from?

Prices read from the OpenRouter model list through looot on 2026-10-13. The list is readable through looot with one free call: looot run openrouter-models --input '{}'.

## What does :batch mean in a model id?

It is the batch variant of the same model on the OpenRouter list, with its own price. Most batch rows here cost less than the standard row, but a few DeepSeek and Z.ai batch rows charge more for input, so compare both rows.

## How often is this page updated?

When the list is read again. Every price carries the date it was read, so an old row is never shown as today's price.
