What is Gemma 4 31B IT?

What Gemma 4 31B IT is for

Largest Gemma 4 instruction model for open, self-hosted chat and reasoning. The registry places it in the gemma family with a release date of 2026-04-02. This profile describes its documented interface and how to evaluate it for the intended task.

Inputs and request limits

The recorded inputs are text and image, with text output. The registry lists a 262,144-token context window and up to 32,768 output tokens. It also declares reasoning, function calling and structured output. These are specifications, not a measured quality or speed ranking. A host can impose its own request limits and support a different subset of features.

Deployment and cost

The registry marks Gemma 4 31B IT as an open-weight model. Check the linked checkpoint’s licence and runtime requirements before downloading or deploying it. Open weights describe availability, while licence terms determine permitted use. Local inference still requires hardware; a hosted route can charge separately.

No independently checked token rate is added from a hosting alias. Use the route’s current price and billing unit when comparing cost, including output, reasoning, cache behavior and retries where applicable.

What to test

Test photographs, screenshots and documents with the detail your application needs to read. Include small text, crowded layouts and questions whose answer is absent. Check whether the answer is supported by the image instead of accepting a plausible description.

Evidence and related models

This is a registry-sourced profile. A model-specific publisher document has not yet been confirmed; access and specifications should be checked before an integration decision. SyncDev has not independently benchmarked Gemma 4 31B IT.

Tasks and inputs

Gemma 4 31B IT is listed for Image-text-to-text, Text generation. It accepts text, image and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.

Capacity and cost

Documented limits: 262.14K context and 32.77K maximum output. The listed route charges $0.10 input and $0.34 output per million tokens. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.

Choosing a deployment

The weights are downloadable under the publisher’s model licence. Check runtime support and size the complete model and working context for your expected concurrency.
