Capabilities

What Google: Gemini 3.1 Pro Preview (batch) can do.

Reasoning

Extended reasoning

Works through problems step by step before answering, trading latency for accuracy on harder tasks.

Adjustable effort

Choose how much the model deliberates per request — trade speed for depth as the task demands.

Multimodal

Image understanding

Reads and reasons over images alongside text in the same prompt.

Audio

Accepts or produces audio as part of the conversation.

Video input

Takes video as an input modality alongside text and images.

File input

Reads uploaded files — documents, spreadsheets, code — directly in context.

Development

Tool calling

Calls external functions mid-response, then continues reasoning from the result.

Structured output

Returns responses constrained to a JSON schema, ready to parse without cleanup.

Streaming

Streams tokens as they're generated instead of waiting on the full response.
