# Gladia Provider

The [Gladia](https://gladia.io/) provider contains language model support for the Gladia transcription API.

## Setup

The Gladia provider is available in the `@ai-sdk/gladia` module. You can install it with

<Tabs items={['pnpm', 'npm', 'yarn', 'bun']}>
  <Tab>
    <Snippet text="pnpm add @ai-sdk/gladia" dark />
  </Tab>
  <Tab>
    <Snippet text="npm install @ai-sdk/gladia" dark />
  </Tab>
  <Tab>
    <Snippet text="yarn add @ai-sdk/gladia" dark />
  </Tab>

  <Tab>
    <Snippet text="bun add @ai-sdk/gladia" dark />
  </Tab>
</Tabs>

## Provider Instance

You can import the default provider instance `gladia` from `@ai-sdk/gladia`:

```ts
import { gladia } from '@ai-sdk/gladia';
```

If you need a customized setup, you can import `createGladia` from `@ai-sdk/gladia` and create a provider instance with your settings:

```ts
import { createGladia } from '@ai-sdk/gladia';

const gladia = createGladia({
  // custom settings, e.g.
  fetch: customFetch,
});
```

You can use the following optional settings to customize the Gladia provider instance:

- **apiKey** _string_

  API key that is being sent using the `Authorization` header.
  It defaults to the `GLADIA_API_KEY` environment variable.

- **headers** _Record&lt;string,string&gt;_

  Custom headers to include in the requests.

- **fetch** _(input: RequestInfo, init?: RequestInit) => Promise&lt;Response&gt;_

  Custom [fetch](https://developer.mozilla.org/en-US/docs/Web/API/fetch) implementation.
  Defaults to the global `fetch` function.
  You can use it as a middleware to intercept requests,
  or to provide a custom fetch implementation for e.g. testing.

## Transcription Models

You can create models that call the [Gladia transcription API](https://docs.gladia.io/chapters/pre-recorded-stt/getting-started)
using the `.transcription()` factory method.

```ts
const model = gladia.transcription();
```

You can also pass additional provider-specific options using the `providerOptions` argument. For example, supplying the `summarize` option will enable summaries for sections of content.

```ts highlight="6"
import { experimental_transcribe as transcribe } from 'ai';
import { gladia } from '@ai-sdk/gladia';
import { readFile } from 'fs/promises';

const result = await transcribe({
  model: gladia.transcription(),
  audio: await readFile('audio.mp3'),
  providerOptions: { gladia: { summarize: true } },
});
```

<Note>
  Gladia does not have various models, so you can omit the standard `model` id
  parameter.
