You can now access Google's latest model, Gemini 3 Pro, via Vercel's AI Gateway with no other provider accounts required.

Gemini 3 Pro excels at challenging tasks involving reasoning or agentic workflows. In particular, the model improves on Gemini 2.5 Pro's performance in multi-step function calling, planning, reasoning over complex images/long documents, and instruction following.

To use Gemini 3 Pro in AI Gateway with the AI SDK, set model to google/gemini-3.0-pro-preview. Gemini 3 Pro is a reasoning model, and you can specify the level of thinking. Include the providerOptions configuration with includeThoughts like the example below to enable reasoning text.

import { streamText } from 'ai';
const result = streamText({
  model: 'google/gemini-3-pro-preview',
  prompt:
  `Analyze the attached technical report and all included diagrams.
   Identify the main objective, extract data into a table, summarize each
   diagram, and list inconsistencies between text and visuals.
   Cite all supporting page and figure references.`,
  providerOptions: {
    google: {
      thinkingConfig: {
        includeThoughts: true,
      }
    }
  },
});

AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.
