Gemini 3 Pro now available in Vercel AI Gateway

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.
