You can now access OpenAI's latest GPT-5.2 models with Vercel's [AI Gateway](https://vercel.com/ai-gateway) and no other provider accounts required.

These models perform better than the GPT-5.1 model series, with noted improvements in professional knowledge work, coding, and long-context reasoning. Other highlights include fewer hallucinations, more accurate vision to interpret graphs and visualizations, strong complex front-end work capabilities, and better information retention working with long documents.

There are 3 models available on AI Gateway:

- GPT-5.2 Chat  (`openai/gpt-5.2-chat`) is the model used in ChatGPT, best suited for everyday work and learning.
- GPT-5.2 (`openai/gpt-5.2`) is for deeper work and complex tasks involving coding or long documents.
- GPT-5.2 Pro (`openai/gpt-5.2-pro`) is best suited for the most difficult questions and tasks with large amounts of reasoning.

To use the GPT-5.2 models with the [AI SDK](https://ai-sdk.dev/), set the model to the respective model slug (noted above):

```tsx
import { streamText } from 'ai';
const result = streamText({
  model: 'openai/gpt-5.2-pro',
  prompt:
    `Create a single-page aurora sky visualizer app in a single HTML file. 
     It should display a realistic animated aurora borealis night sky.
     Change solar activity level, color palette (green/purple/mixed),
     and sky clarity (haze, clear, light clouds).
     The UI should feel tranquil, immersive, and visually realistic,
     with smooth transitions and subtle ambient motion.`
  providerOptions: {
    openai: {
      reasoningSummary: 'detailed',
      reasoningEffort: 'high',
    },
  },
});
```

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.
