## Usage

* [ TypeScript ](#tab-panel-1096)
* [ cURL ](#tab-panel-1097)

TypeScript

```
const response = await env.AI.run(  'openai/gpt-4o-transcribe',  { file: 'data:audio/wav;base64,<...>' },)console.log(response)
```

Terminal window

```
curl https://api.cloudflare.com/client/v4/accounts/$CLOUDFLARE_ACCOUNT_ID/ai/run \  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \  --header "Content-Type: application/json" \  --data '{  "model": "openai/gpt-4o-transcribe",  "input": {    "file": "data:audio/wav;base64,<...>"  }}'
```

* [ Output ](#tab-panel-1094)
* [ Raw response ](#tab-panel-1095)

Hello

```
{  "gatewayMetadata": {    "keySource": "Unified"  },  "result": {    "text": "Hello"  },  "state": "Completed"}
```

## Examples

**With Language Hint**  — Transcribe with a language hint for better accuracy 

* [ TypeScript ](#tab-panel-1100)
* [ cURL ](#tab-panel-1101)

TypeScript

```
const response = await env.AI.run(  'openai/gpt-4o-transcribe',  { file: 'data:audio/wav;base64,<...>', language: 'en' },)console.log(response)
```

Terminal window

```
curl https://api.cloudflare.com/client/v4/accounts/$CLOUDFLARE_ACCOUNT_ID/ai/run \  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \  --header "Content-Type: application/json" \  --data '{  "model": "openai/gpt-4o-transcribe",  "input": {    "file": "data:audio/wav;base64,<...>",    "language": "en"  }}'
```

* [ Output ](#tab-panel-1098)
* [ Raw response ](#tab-panel-1099)

Hello

```
{  "gatewayMetadata": {    "keySource": "Unified"  },  "result": {    "text": "Hello"  },  "state": "Completed"}
```

**Guided Transcription**  — Use a prompt to guide transcription style and context 

* [ TypeScript ](#tab-panel-1104)
* [ cURL ](#tab-panel-1105)

TypeScript

```
const response = await env.AI.run(  'openai/gpt-4o-transcribe',  {    file: 'data:audio/wav;base64,<...>',    prompt: 'This is a technical discussion about Kubernetes and cloud-native architecture.',    language: 'en',  },)console.log(response)
```

Terminal window

```
curl https://api.cloudflare.com/client/v4/accounts/$CLOUDFLARE_ACCOUNT_ID/ai/run \  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \  --header "Content-Type: application/json" \  --data '{  "model": "openai/gpt-4o-transcribe",  "input": {    "file": "data:audio/wav;base64,<...>",    "prompt": "This is a technical discussion about Kubernetes and cloud-native architecture.",    "language": "en"  }}'
```

* [ Output ](#tab-panel-1102)
* [ Raw response ](#tab-panel-1103)

This is a technical discussion about Kubernetes and cloud-native architecture.

```
{  "gatewayMetadata": {    "keySource": "Unified"  },  "result": {    "text": "This is a technical discussion about Kubernetes and cloud-native architecture."  },  "state": "Completed"}
```

**High Temperature**  — Higher temperature for more varied transcription 

* [ TypeScript ](#tab-panel-1108)
* [ cURL ](#tab-panel-1109)

TypeScript

```
const response = await env.AI.run(  'openai/gpt-4o-transcribe',  { file: 'data:audio/wav;base64,<...>', temperature: 0.5 },)console.log(response)
```

Terminal window

```
curl https://api.cloudflare.com/client/v4/accounts/$CLOUDFLARE_ACCOUNT_ID/ai/run \  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \  --header "Content-Type: application/json" \  --data '{  "model": "openai/gpt-4o-transcribe",  "input": {    "file": "data:audio/wav;base64,<...>",    "temperature": 0.5  }}'
```

* [ Output ](#tab-panel-1106)
* [ Raw response ](#tab-panel-1107)

Hello, world!

```
{  "gatewayMetadata": {    "keySource": "Unified"  },  "result": {    "text": "Hello, world!"  },  "state": "Completed"}
```

## Parameters

* [ Input ](#tab-panel-1110)
* [ Output ](#tab-panel-1111)

file

`string`requiredThe audio file as a data URI (data:audio/...;base64,...) or HTTPS URL. Supported formats: flac, mp3, mp4, mpeg, mpga, m4a, ogg, wav, webm.

language

`string`The language of the input audio. Supplying the input language in ISO-639-1 format will improve accuracy and latency.

prompt

`string`An optional text to guide the model's style or continue a previous audio segment. The prompt should match the audio language.

temperature

`number`minimum: 0maximum: 1The sampling temperature, between 0 and 1\. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic. Defaults to 0 if omitted.

text

`string`The transcribed text.
