# Vercel AI Gateway

> Configure the Vercel AI Gateway provider profile in Loong.

# Vercel AI Gateway

Use this when Vercel AI Gateway sits in front of the actual model vendors and you want that ownership boundary documented directly in the provider profile.

## At A Glance

| Field            | Value                                                   |
| ---------------- | ------------------------------------------------------- |
| Built-in kind    | `vercel_ai_gateway`                                     |
| Provider group   | Gateway And Compatibility Providers                     |
| Protocol family  | `openai_chat_completions`                               |
| Feature family   | `openai_compatible`                                     |
| Auth scheme      | `bearer`                                                |
| Credential envs  | AI\_GATEWAY\_API\_KEY, VERCEL\_API\_KEY                 |
| Aliases          | `vercel-ai-gateway`, `vercel_ai`, `vercel-ai`, `vercel` |
| Default base URL | `https://ai-gateway.vercel.sh/v1`                       |
| Request endpoint | `https://ai-gateway.vercel.sh/v1/chat/completions`      |
| Models endpoint  | `https://ai-gateway.vercel.sh/v1/models`                |

## Minimal Config

```toml theme={null}
active_provider = "vercel_ai_gateway"

[providers.vercel_ai_gateway]
kind = "vercel_ai_gateway"
api_key = { env = "AI_GATEWAY_API_KEY" }
model = "auto"
```

## Verify It

```bash theme={null}
loong doctor
loong runtime models list
loong ask --message "Say hello and name the active provider."
```

If `runtime models list` is unreliable for this account or region, pin an explicit `provider.model` or add `preferred_models` instead of leaving recovery implicit.
