# Profile

Loading profile. `portable` serves the `defer_loading` tools with router-built search and call wrappers on any model and keeps the catalog fixed. `universal` defers every wrappable tool behind the same wrappers so the provider-facing tool list never changes, and rebuilds the catalog from each request so tools can be added or removed mid-conversation.

## Example Usage

```typescript theme={null}
import { Profile } from "@openrouter/sdk/models";

let value: Profile = "universal";

// Open enum: unrecognized values are captured as Unrecognized<string>
```

## Values

```typescript theme={null}
"portable" | "universal" | Unrecognized<string>
```
