# OpenAI TypeScript and JavaScript API Library

[![NPM version](https://raw.githubusercontent.com/openai/openai-node/main/<https:/img.shields.io/npm/v/openai.svg)>)](https://npmjs.org/package/openai) ![npm bundle size](https://img.shields.io/bundlephobia/minzip/openai)

This library provides convenient access to the OpenAI REST API from TypeScript or JavaScript.

It is generated from our [OpenAPI specification](https://github.com/openai/openai-openapi).

To learn how to use the OpenAI API, check out our [API Reference](https://platform.openai.com/docs/api-reference) and [Documentation](https://platform.openai.com/docs).

## Installation

```sh
npm install openai
```

### Installation with Deno

Deno can import the package directly from npm:

```ts
import OpenAI from 'npm:openai';
```

## Usage

The full API of this library can be found in [api.md file](api.md) along with many [code examples](https://github.com/openai/openai-node/tree/main/examples).

The primary API for interacting with OpenAI models is the [Responses API](https://platform.openai.com/docs/api-reference/responses). You can generate text from the model with the code below.

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env['OPENAI_API_KEY'], // This is the default and can be omitted
});

const response = await client.responses.create({
  model: 'gpt-5.5',
  instructions: 'You are a coding assistant that talks like a pirate',
  input: 'Are semicolons optional in JavaScript?',
});

console.log(response.output_text);
```

### Multi-turn conversations

When you manage Responses API conversation history manually, preserve output items in order. Filtering
`response.output` to messages can drop required reasoning or tool-call items and cause the next request to
fail.

Use the SDK's `toResponseInputItems()` helper to normalize all replayable output items before adding them to
the next request. For simple continuation, you can pass `previous_response_id` instead.

See the [manual conversation state example](examples/responses/manual-conversation-state.ts) and
[conversation state guide](https://developers.openai.com/api/docs/guides/conversation-state).

The previous standard (supported indefinitely) for generating text is the [Chat Completions API](https://platform.openai.com/docs/api-reference/chat). You can use that API to generate text from the model with the code below.

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env['OPENAI_API_KEY'], // This is the default and can be omitted
});

const completion = await client.chat.completions.create({
  model: 'gpt-5.5',
  messages: [
    { role: 'developer', content: 'Talk like a pirate.' },
    { role: 'user', content: 'Are semicolons optional in JavaScript?' },
  ],
});

console.log(completion.choices[0].message.content);
```

## Vision

Use the Responses API to analyze images and generate text about visual content.

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env['OPENAI_API_KEY'], // This is the default and can be omitted
});

const response = await client.responses.create({
  model: 'gpt-5.5',
  input: [
    {
      role: 'user',
      content: [
        { type: 'input_text', text: 'What is in this image?' },
        {
          type: 'input_image',
          image_url:
            'https://api.nga.gov/iiif/a2e6da57-3cd1-4235-b20e-95dcaefed6c8/full/!800,800/0/default.jpg',
        },
      ],
    },
  ],
});

console.log(response.output_text);
```

## Workload Identity Authentication

For secure, automated environments like cloud-managed Kubernetes, Azure, and GCP, you can use workload identity authentication with short-lived tokens from cloud identity providers instead of long-lived API keys.

The `workloadIdentity` parameter is mutually exclusive with `apiKey`.

The required fields are `identityProviderId`, `serviceAccountId`, and `provider`.

### Kubernetes (service account tokens)

```ts
import OpenAI from 'openai';
import { k8sServiceAccountTokenProvider } from 'openai/auth';

const client = new OpenAI({
  workloadIdentity: {
    identityProviderId: 'idp-123',
    serviceAccountId: 'sa-456',
    provider: k8sServiceAccountTokenProvider('/var/run/secrets/kubernetes.io/serviceaccount/token'),
  },
});

const response = await client.chat.completions.create({
  model: 'gpt-5.5',
  messages: [{ role: 'user', content: 'Hello!' }],
});
```

### Azure (managed identity)

```ts
import OpenAI from 'openai';
import { azureManagedIdentityTokenProvider } from 'openai/auth';

const client = new OpenAI({
  workloadIdentity: {
    identityProviderId: 'idp-123',
    serviceAccountId: 'sa-456',
    provider: azureManagedIdentityTokenProvider(),
  },
});
```

### GCP (compute engine metadata)

```ts
import OpenAI from 'openai';
import { gcpIDTokenProvider } from 'openai/auth';

const client = new OpenAI({
  workloadIdentity: {
    identityProviderId: 'idp-123',
    serviceAccountId: 'sa-456',
    provider: gcpIDTokenProvider(),
  },
});
```

### Custom subject token provider

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  workloadIdentity: {
    identityProviderId: 'idp-123',
    serviceAccountId: 'sa-456',
    provider: {
      tokenType: 'jwt',
      getToken: async () => {
        return 'your-jwt-token';
      },
    },
  },
});
```

You can also customize the token refresh buffer (default is 1200 seconds (20 minutes) before expiration):

```ts
import OpenAI from 'openai';
import { k8sServiceAccountTokenProvider } from 'openai/auth';

const client = new OpenAI({
  workloadIdentity: {
    identityProviderId: 'idp-123',
    serviceAccountId: 'sa-456',
    provider: k8sServiceAccountTokenProvider('/var/token'),
    refreshBufferSeconds: 120.0,
  },
});
```

## Streaming responses

We provide support for streaming responses using Server-Sent Events (SSE).

```ts
import OpenAI from 'openai';

const client = new OpenAI();

const stream = await client.responses.create({
  model: 'gpt-5.5',
  input: 'Say "Sheep sleep deep" ten times fast!',
  stream: true,
});

for await (const event of stream) {
  console.log(event);
}
```

## File uploads

Request parameters that correspond to file uploads can be passed in many different forms:

- `File` (or an object with the same structure)
- a `fetch` `Response` (or an object with the same structure)
- an `fs.ReadStream`
- the return value of our `toFile` or `toStreamingFile` helpers

```ts
import fs from 'fs';
import OpenAI, { toFile, toStreamingFile } from 'openai';

const client = new OpenAI();

// If you have access to Node `fs` we recommend using `fs.createReadStream()`:
await client.files.create({ file: fs.createReadStream('input.jsonl'), purpose: 'fine-tune' });

// Or if you have the web `File` API you can pass a `File` instance:
await client.files.create({ file: new File(['my bytes'], 'input.jsonl'), purpose: 'fine-tune' });

// You can also pass a `fetch` `Response`:
await client.files.create({
  file: await fetch('https://somesite/input.jsonl'),
  purpose: 'fine-tune',
});

// Finally, if none of the above are convenient, you can use our `toFile` helper:
await client.files.create({
  file: await toFile(Buffer.from('my bytes'), 'input.jsonl'),
  purpose: 'fine-tune',
});
await client.files.create({
  file: await toFile(new Uint8Array([0, 1, 2]), 'input.jsonl'),
  purpose: 'fine-tune',
});

// `toFile()` creates a web File, so it must buffer stream inputs before sending them.
// Use `toStreamingFile()` to stream an arbitrary web, Node, or cloud-storage stream directly:
await client.files.create({
  file: toStreamingFile(myReadableStream, 'input.jsonl', { type: 'application/jsonl' }),
  purpose: 'fine-tune',
});
```

## Webhook Verification

Verifying webhook signatures is _optional but encouraged_.

Webhook verification is asynchronous. Always `await` `unwrap()` or `verifySignature()` before trusting
the event.

For more information about webhooks, see [the API docs](https://platform.openai.com/docs/guides/webhooks).

### Parsing webhook payloads

For most use cases, you will likely want to verify the webhook and parse the payload at the same time. To achieve this, we provide the method `client.webhooks.unwrap()`, which parses a webhook request and verifies that it was sent by OpenAI. This method will throw an error if the signature is invalid.

Note that the `body` parameter must be the raw JSON string sent from the server (do not parse it first). The `.unwrap()` method will parse this JSON for you into an event object after verifying the webhook was sent from OpenAI.

```ts
import { headers } from 'next/headers';
import OpenAI from 'openai';

const client = new OpenAI({
  webhookSecret: process.env.OPENAI_WEBHOOK_SECRET, // env var used by default; explicit here.
});

export async function webhook(request: Request) {
  const headersList = headers();
  const body = await request.text();

try {
    const event = await client.webhooks.unwrap(body, headersList);

switch (event.type) {
      case 'response.completed':
        console.log('Response completed:', event.data);
        break;
      case 'response.failed':
        console.log('Response failed:', event.data);
        break;
      default:
        console.log('Unhandled event type:', event.type);
    }

return Response.json({ message: 'ok' });
  } catch (error) {
    console.error('Invalid webhook signature:', error);
    return new Response('Invalid signature', { status: 400 });
  }
}
```

### Verifying webhook payloads directly

In some cases, you may want to verify the webhook separately from parsing the payload. If you prefer to handle these steps separately, we provide the method `client.webhooks.verifySignature()` to _only verify_ the signature of a webhook request. Like `.unwrap()`, this method will throw an error if the signature is invalid.

Note that the `body` parameter must be the raw JSON string sent from the server (do not parse it first). You will then need to parse the body after verifying the signature.

```ts
import { headers } from 'next/headers';
import OpenAI from 'openai';

const client = new OpenAI({
  webhookSecret: process.env.OPENAI_WEBHOOK_SECRET, // env var used by default; explicit here.
});

export async function webhook(request: Request) {
  const headersList = headers();
  const body = await request.text();

try {
    await client.webhooks.verifySignature(body, headersList);

// Parse the body after verification
    const event = JSON.parse(body);
    console.log('Verified event:', event);

return Response.json({ message: 'ok' });
  } catch (error) {
    console.error('Invalid webhook signature:', error);
    return new Response('Invalid signature', { status: 400 });
  }
}
```

## Handling errors

When the library is unable to connect to the API,
or if the API returns a non-success status code (i.e., 4xx or 5xx response),
a subclass of `APIError` will be thrown:

```ts
const job = await client.fineTuning.jobs
 .create({ model: 'gpt-4o', training_file: 'file-abc123' })
 .catch(async (err) => {
 if (err instanceof OpenAI.APIError) {
 console.log(err.request_id);
 console.log(err.status); // 400
 console.log(err.name); // BadRequestError
 console.log(err.headers); // {server: 'nginx', ...}
 } else {
 throw err;
 }
 });
```

Error codes are as follows:

| Status Code | Error Type                 |
| ----------- | -------------------------- |
| 400         | `BadRequestError`          |
| 401         | `AuthenticationError`      |
| 403         | `PermissionDeniedError`    |
| 404         | `NotFoundError`            |
| 422         | `UnprocessableEntityError` |
| 429         | `RateLimitError`           |
| >=500       | `InternalServerError`      |
| N/A         | `APIConnectionError`       |

### Retries

Certain errors will be automatically retried 2 times by default, with a short exponential backoff.
Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict,
429 Rate Limit, and >=500 Internal errors will all be retried by default.

You can use the `maxRetries` option to configure or disable this:

```js
// Configure the default for all requests:
const client = new OpenAI({
 maxRetries: 0, // default is 2
});

// Or, configure per-request:
await client.chat.completions.create({ messages: [{ role: 'user', content: 'How can I get the name of the current day in JavaScript?' }], model: 'gpt-5.5' }, {
  maxRetries: 5,
});
```

### Timeouts

Requests time out after 10 minutes by default. You can configure this with a `timeout` option:

```ts
// Configure the default for all requests:
const client = new OpenAI({
 timeout: 20 * 1000, // 20 seconds (default is 10 minutes)
});

// Override per-request:
await client.chat.completions.create({ messages: [{ role: 'user', content: 'How can I list all files in a directory using Python?' }], model: 'gpt-5.5' }, {
  timeout: 5 * 1000,
});
```

On timeout, an `APIConnectionTimeoutError` is thrown.

Note that requests which time out will be [retried twice by default](#retries).

## Request IDs

> For more information on debugging requests, see [these docs](https://platform.openai.com/docs/api-reference/debugging-requests)

All object responses in the SDK provide a `_request_id` property which is added from the `x-request-id` response header so that you can quickly log failing requests and report them back to OpenAI.

```ts
const response = await client.responses.create({ model: 'gpt-5.5', input: 'testing 123' });
console.log(response._request_id); // req_123
```

You can also access the Request ID using the `.withResponse()` method:

```ts
const { data: stream, request_id } = await openai.responses
  .create({
    model: 'gpt-5.5',
    input: 'Say this is a test',
    stream: true,
  })
  .withResponse();
```

## Auto-pagination

List methods in the OpenAI API are paginated.
You can use the `for await … of` syntax to iterate through items across all pages:

```ts
async function fetchAllFineTuningJobs(params) {
  const allFineTuningJobs = [];
  // Automatically fetches more pages as needed.
  for await (const fineTuningJob of client.fineTuning.jobs.list({ limit: 20 })) {
    allFineTuningJobs.push(fineTuningJob);
  }
  return allFineTuningJobs;
}
```

Alternatively, you can request a single page at a time:

```ts
let page = await client.fineTuning.jobs.list({ limit: 20 });
for (const fineTuningJob of page.data) {
  console.log(fineTuningJob);
}

// Convenience methods are provided for manually paginating:
while (page.hasNextPage()) {
  page = await page.getNextPage();
  // ...
}
```

## Realtime API

The Realtime API enables you to build low-latency, multi-modal conversational experiences. It currently supports text and audio as both input and output, as well as [function calling](https://platform.openai.com/docs/guides/function-calling) through a `WebSocket` connection.

```ts
import { OpenAIRealtimeWebSocket } from 'openai/realtime/websocket';

const rt = new OpenAIRealtimeWebSocket({ model: 'gpt-realtime-2' });

rt.on('response.output_text.delta', (event) => process.stdout.write(event.delta));
```

For more information see [docs/realtime.md](docs/realtime.md).

## Microsoft Azure OpenAI

To use this library with [Azure OpenAI](https://learn.microsoft.com/azure/ai-services/openai/overview), use the `AzureOpenAI`
class instead of the `OpenAI` class.

> [!IMPORTANT]
> The Azure API shape slightly differs from the core API shape which means that the static types for responses / params
> won't always be correct.

```ts
import { AzureOpenAI } from 'openai';
import { getBearerTokenProvider, DefaultAzureCredential } from '@azure/identity';

const credential = new DefaultAzureCredential();
const scope = 'https://cognitiveservices.azure.com/.default';
const azureADTokenProvider = getBearerTokenProvider(credential, scope);

const openai = new AzureOpenAI({
 azureADTokenProvider,
 apiVersion: '<The API version, e.g. 2024-10-01-preview>',
});

const result = await openai.chat.completions.create({
  model: 'gpt-5.5',
  messages: [{ role: 'user', content: 'Say hello!' }],
});

console.log(result.choices[0]!.message?.content);
```

For more information on support for the Azure API, see [docs/azure.md](docs/azure.md).

## Amazon Bedrock

To use this library with [Amazon Bedrock's OpenAI-compatible API](https://docs.aws.amazon.com/bedrock/latest/userguide/models-api-compatibility.html), configure the standard `OpenAI` client with the Bedrock provider:

```ts
import OpenAI from 'openai';
import { bedrock } from 'openai/providers/bedrock/aws';

const client = new OpenAI({
  provider: bedrock({ region: 'us-west-2' }),
});

const response = await client.responses.create({
  model: 'openai.gpt-5.4',
  input: 'Say hello!',
});

console.log(response.output_text);
```

Use a model that [supports the Responses API](https://docs.aws.amazon.com/bedrock/latest/userguide/models-api-compatibility.html). A model returned by the Models API may support a different Bedrock inference API instead.

This uses the regional `https://bedrock-mantle.<region>.api.aws/openai/v1` endpoint. The region can also come from `AWS_REGION` or `AWS_DEFAULT_REGION`, and `AWS_BEDROCK_BASE_URL` can override the endpoint.

The AWS entrypoint uses the standard AWS credential chain by default. It also accepts a named profile, static credentials, or a custom credential provider. Install its peer dependencies before importing it:

```bash
npm install @aws-sdk/credential-provider-node @smithy/hash-node @smithy/signature-v4
```

The AWS entrypoint uses normal static imports so bundlers and serverless packagers can trace these dependencies. If one is missing, importing `openai/providers/bedrock/aws` fails immediately with the runtime's normal module-not-found error, for example:

```text
Cannot find module '@aws-sdk/credential-provider-node'
```

For Bedrock API key authentication, import `bedrock` from `openai/providers/bedrock` instead. That entrypoint has no AWS dependencies and works in browser-compatible runtimes when `dangerouslyAllowBrowser` is enabled. SigV4 authentication is supported in Node.js and compatible server runtimes and requires replayable request bodies. The legacy, bearer-only `BedrockOpenAI` class remains available for compatibility.

For more information on support for Amazon Bedrock, see [docs/bedrock.md](docs/bedrock.md).

## Advanced Usage

### Accessing raw Response data (e.g., headers)

The "raw" `Response` returned by `fetch()` can be accessed through the `.asResponse()` method on the `APIPromise` type that all methods return.
This method returns as soon as the headers for a successful response are received and does not consume the response body, so you are free to write custom parsing or streaming logic.

You can also use the `.withResponse()` method to get the raw `Response` along with the parsed data.
Unlike `.asResponse()` this method consumes the body, returning once it is parsed.

```ts
const client = new OpenAI();

const httpResponse = await client.responses
  .create({ model: 'gpt-5.5', input: 'say this is a test.' })
  .asResponse();

// access the underlying web standard Response object
console.log(httpResponse.headers.get('X-My-Header'));
console.log(httpResponse.statusText);

const { data: modelResponse, response: raw } = await client.responses
  .create({ model: 'gpt-5.5', input: 'say this is a test.' })
  .withResponse();
console.log(raw.headers.get('X-My-Header'));
console.log(modelResponse);
```

### Logging

> [!IMPORTANT]
> All log messages are intended for debugging only. The format and content of log messages
> may change between releases.

#### Log levels

The log level can be configured in two ways:

1. Via the `OPENAI_LOG` environment variable
2. Using the `logLevel` client option (overrides the environment variable if set)

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  logLevel: 'debug', // Show all log messages
});
```

Available log levels, from most to least verbose:

- `'debug'` - Show debug messages, info, warnings, and errors
- `'info'` - Show info messages, warnings, and errors
- `'warn'` - Show warnings and errors (default)
- `'error'` - Show only errors
- `'off'` - Disable all logging

At the `'debug'` level, all HTTP requests and responses are logged, including headers and bodies.
Some authentication-related headers are redacted, but sensitive data in request and response bodies
may still be visible.

#### Custom logger

By default, this library logs to `globalThis.console`. You can also provide a custom logger.
Most logging libraries are supported, including [pino](https://www.npmjs.com/package/pino), [winston](https://www.npmjs.com/package/winston), [bunyan](https://www.npmjs.com/package/bunyan), [consola](https://www.npmjs.com/package/consola), and [signale](https://www.npmjs.com/package/signale). If your logger doesn't work, please open an issue.

When providing a custom logger, the `logLevel` option still controls which messages are emitted, messages
below the configured level will not be sent to your logger.

```ts
import OpenAI from 'openai';
import pino from 'pino';

const logger = pino();

const client = new OpenAI({
  logger: logger.child({ name: 'OpenAI' }),
  logLevel: 'debug', // Send all messages to pino, allowing it to filter
});
```

### Making custom/undocumented requests

This library is typed for convenient access to the documented API. If you need to access undocumented
endpoints, params, or response properties, the library can still be used.

#### Undocumented endpoints

To make requests to undocumented endpoints, you can use `client.get`, `client.post`, and other HTTP verbs.
Options on the client, such as retries, will be respected when making these requests.

```ts
await client.post('/some/path', {
  body: { some_prop: 'foo' },
  query: { some_query_arg: 'bar' },
});
```

#### Undocumented request params

To make requests using undocumented parameters, you may use `// @ts-expect-error` on the undocumented
parameter. This library doesn't validate at runtime that the request matches the type, so any extra values you
send will be sent as-is.

```ts
client.chat.completions.create({
  // ...
  // @ts-expect-error baz is not yet public
  baz: 'undocumented option',
});
```

For requests with the `GET` verb, any extra params will be in the query, all other requests will send the
extra param in the body.

If you want to explicitly send an extra argument, you can do so with the `query`, `body`, and `headers` request
options.

#### Undocumented response properties

To access undocumented response properties, you may access the response object with `// @ts-expect-error` on
the response object, or cast the response object to the requisite type. Like the request params, we do not
validate or strip extra properties from the response from the API.

### Customizing the fetch client

If you want to use a different `fetch` function, you can either polyfill the global:

```ts
import fetch from 'my-fetch';

globalThis.fetch = fetch;
```

Or pass it to the client:

```ts
import OpenAI from 'openai';
import fetch from 'my-fetch';

const client = new OpenAI({ fetch });
```

### Fetch options

If you want to set custom `fetch` options without overriding the `fetch` function, you can provide a `fetchOptions` object when instantiating the client or making a request. (Request-specific options override client options.)

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  fetchOptions: {
    // `RequestInit` options
  },
});
```

#### Configuring proxies

To modify proxy behavior, you can provide custom `fetchOptions` that add runtime-specific proxy
options to requests:

**Node** [[docs](https://github.com/nodejs/undici/blob/main/docs/docs/api/ProxyAgent.md#example---proxyagent-with-fetch)]

```ts
import OpenAI from 'openai';
import { fetch, ProxyAgent } from 'undici';

const proxyAgent = new ProxyAgent('http://localhost:8888');
const client = new OpenAI({
  fetch,
  fetchOptions: {
    dispatcher: proxyAgent,
  },
});
```

Undici-specific options like `dispatcher` must be paired with the matching `fetch` implementation.

**Bun** [[docs](https://bun.sh/guides/http/proxy)]

```ts
import OpenAI from 'openai';

const client = new OpenAI({
  fetchOptions: {
    proxy: 'http://localhost:8888',
  },
});
```

**Deno** [[docs](https://docs.deno.com/api/deno/~/Deno.createHttpClient)]

```ts
import OpenAI from 'npm:openai';

const httpClient = Deno.createHttpClient({ proxy: { url: 'http://localhost:8888' } });
const client = new OpenAI({
  fetchOptions: {
    client: httpClient,
  },
});
```

### Mutual TLS

The API mTLS beta combines your API key with a client certificate. For enrollment, certificate requirements, activation, and supported endpoints, see the [OpenAI Mutual TLS Beta Program](https://help.openai.com/en/articles/10876024-openai-mutual-tls-beta-program). Configure mTLS on your runtime's HTTP transport, then pass that transport to the SDK with `fetch` and `fetchOptions`. Set `baseURL` to the mTLS endpoint explicitly:

```ts
import { readFile } from 'node:fs/promises';
import { Agent, fetch as undiciFetch } from 'undici';
import OpenAI from 'openai';

const dispatcher = new Agent({
  connect: {
    // One PEM chain: leaf certificate first, then required intermediates.
    cert: await readFile('/path/to/client-cert-chain.pem'),
    key: await readFile('/path/to/client-key.pem'),
  },
});

const client = new OpenAI({
  apiKey: process.env['OPENAI_API_KEY'],
  baseURL: 'https://mtls.api.openai.com/v1',
  fetch: undiciFetch,
  fetchOptions: {
    dispatcher,
    redirect: 'manual',
  },
});
```

Use `https://mtls-eu.api.openai.com/v1` for EU Data Residency. The example uses manual redirects so the certificate-bearing transport does not automatically follow a redirect to another host. Close transports your application creates when they are no longer needed.

## Semantic versioning

This package generally follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions, though certain backwards-incompatible changes may be released as minor versions:

1. Changes that only affect static types, without breaking runtime behavior.
2. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals.)_
3. Changes that we do not expect to impact the vast majority of users in practice.

We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.

We are keen for your feedback; please open an [issue](https://www.github.com/openai/openai-node/issues) with questions, bugs, or suggestions.

## Requirements

TypeScript >= 4.9 is supported.

The following runtimes are supported:

- Node.js 22 and 24 LTS. Node.js 22 is the minimum supported version.
- Deno v1.28.0 or higher.
- Bun 1.0 or later.
- Cloudflare Workers.
- Vercel Edge Runtime.
- Jest 28 or greater with the `"node"` environment (`"jsdom"` is not supported at this time).
- Nitro v2.6 or greater.
- Web browsers: disabled by default to avoid exposing your secret API credentials. Enable browser support by explicitly setting `dangerouslyAllowBrowser` to `true`.

### Why is this dangerous?

Enabling the `dangerouslyAllowBrowser` option can be dangerous because it exposes your secret API credentials in the client-side code. Web browsers are inherently less secure than server environments,
  any user with access to the browser can potentially inspect, extract, and misuse these credentials. This could lead to unauthorized access using your credentials and potentially compromise sensitive data or functionality.

### When might this not be dangerous?

In certain scenarios where enabling browser support might not pose significant risks:

- Internal Tools: If the application is used solely within a controlled internal environment where the users are trusted, the risk of credential exposure can be mitigated.
  - Public APIs with Limited Scope: If your API has very limited scope and the exposed credentials do not grant access to sensitive data or critical operations, the potential impact of exposure is reduced.
  - Development or debugging purpose: Enabling this feature temporarily might be acceptable, provided the credentials are short-lived, aren't also used in production environments, or are frequently rotated.

Note that React Native is not supported at this time.

If you are interested in other runtime environments, please open or upvote an issue on GitHub.

Node.js 20 reached end of life on April 30, 2026 and is no longer supported.
Previously published SDK releases remain available, but receive no guaranteed
fixes or security backports for unsupported Node.js versions. See the
[Node.js version support policy](https://github.com/openai/openai-node/blob/main/NODE_VERSION_POLICY.md)
for lifecycle, deprecation, and release rules.
