You can now access Google's latest Gemini model, Gemini 3 Flash, with Vercel's [AI Gateway](https://vercel.com/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](https://ai-sdk.dev/), set the model to `google/gemini-3-flash`:

```tsx
import { streamText } from 'ai';
const result = streamText({
  model: 'google/gemini-3-flash',
  prompt:
    `Produce a step-by-step analysis that solves a novel
     problem, exposes intermediate logic, and delivers a final answer
     using minimal tokens and maximal inference density.`
  providerOptions: {
    google: {
      thinkingLevel: 'high',
      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](https://vercel.com/docs/ai-gateway/observability), [Bring Your Own Key support](https://vercel.com/docs/ai-gateway/byok), and intelligent [provider routing](https://vercel.com/docs/ai-gateway/provider-options) with automatic retries.
