Model signal card

Start with the supply line behind the model before you move into deeper buying or key work.

Context window

1.0M

Context length changes whether the model fits short tasks, long documents, or knowledge workflows.

Input price

Input price usually matters more for high-volume calling and batch workloads.

Output price

$12

Output price matters more for writing-heavy, support, and long-answer workflows.

Start with the job this model solves

Gemini 3.1 Pro Preview should not be treated as a brand-name page first. It should be placed back into the real model layer: it comes from Google, sits on the Global model route, and belongs to the Gemini family.

Ask first whether you truly need a 1.0M context window or are just reacting to the phrase “long context.”
Then ask whether your workload cares more about Multimodal -> text ability or about price band and delivery stability.
Then ask whether Google can fit the protocol stack you already run today.

Then read the real decision signals

This model line is best judged through four inputs: modality Multimodal -> text, context 1.0M, prompt cost $2, and completion cost $12. The real question is whether those four signals support the workflow together.

Model: Gemini 3.1 Pro Preview
Provider: Google
Context: 1,048,576
Input price: $2.00 / 1M tokens
Output price: $12.00 / 1M tokens

Finally move into the next action

If the upstream provider already exposes live checking, the next valuable move is to test the real key, protocol fit, and model visibility instead of stopping on a static page.
