# Vertex AI (preview)

The Vertex AI Gemini API gives you access to the latest generative AI models from Google: the Gemini models.

## Dependency Injection

As a prerequisite, ensure that `AngularFire` has been added to your project via
```bash
ng add @angular/fire
```

Provide a Vertex AI instance in the application's `app.config.ts`:

```ts
import { provideFirebaseApp, initializeApp } from '@angular/fire/app';
import { provideVertexAI, getVertexAI } from '@angular/fire/vertexai-preview';

export const appConfig: ApplicationConfig = {
  providers: [
    provideFirebaseApp(() => initializeApp({ ... })),
    provideVertexAI(() => getVertexAI()),
    ...
  ],
  ...,
}
```

Next inject `VertexAI` into your component:

```typescript
import { Component, inject } from '@angular/core';
import { VertexAI } from '@angular/fire/vertexai';

@Component({ ... })
export class MyComponent {
    private vertexAI = inject(VertexAI);
    ...
}
```

## Firebase API

AngularFire wraps the Firebase JS SDK to ensure proper functionality in Angular, while providing the same API.

Update the imports from `import { ... } from 'firebase/vertexai'` to `import { ... } from '@angular/fire/vertexai'` and follow the official documentation.
