Gemini 3 Flash is now available on the Vercel AI Gateway

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

It is Google's most intelligent model that is optimized for speed, with Gemini 3's pro-grade reasoning alongside flash-level latency, efficiency, and cost. Gemini 3 Flash significantly outperforms the previous Gemini 2.5 models, beating Gemini 2.5 Pro across most benchmarks, while using 30% less tokens and is 3x faster at a fraction of the cost.

To use the Gemini 3 Flash with the AI SDK, set the model to google/gemini-3-flash:

1
import { streamText } from 'ai';
2
const result = streamText({
3
  model: 'google/gemini-3-flash',
4
  prompt:
5
    `Produce a step-by-step analysis that solves a novel
6
     problem, exposes intermediate logic, and delivers a final answer
7
     using minimal tokens and maximal inference density.`
8
  providerOptions: {
9
    google: {
10
      thinkingLevel: 'high',
11
      includeThoughts: true
12
    },
13
  },
14
});

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.
