> Summary: This quickstart walks you through getting a credential, finding your branch host, and making your first request to the Neon AI Gateway using the OpenAI SDK. No provider API keys required. Authenticate with your Neon credential.

# Get started with Neon AI Gateway

Make your first inference request in minutes

To set up Neon AI Gateway with an AI coding assistant, install the Neon Platform (`neon`) and Neon AI Gateway skills with the [Neon CLI](/guides/apis-sdks-cli):

```bash
neon skills -s neon -s neon-ai-gateway
```

Without the Neon CLI, run `npx skills add neondatabase/agent-skills -s neon -s neon-ai-gateway` instead.

## Get access

You need a project in AWS US East (Ohio) (`aws-us-east-2`), AWS US East (N. Virginia) (`aws-us-east-1`), AWS Europe (Frankfurt) (`aws-eu-central-1`), or AWS Asia Pacific (Singapore) (`aws-ap-southeast-1`). Support is expanding toward [all regions](/guides/manage-operate-introduction-regions). Using the AI Gateway requires a paid Neon plan with prepaid credits, which gives you the open-weight models. To request access to foundation models, see [Model access](/guides/ai-gateway-index#model-access).

## Create a credential

With the [Neon CLI](/guides/apis-sdks-cli-credentials), run:

```bash
neon credentials create --scope ai_gateway:invoke
```

Or, in the Neon Console, click **Connect** at the top of the sidebar and open the **AI Gateway** tab. Click **Reveal credential** to show `NEON_AI_GATEWAY_TOKEN`, or **Copy snippet** to copy it together with `NEON_AI_GATEWAY_BASE_URL`. Use **Rotate credential** to issue a new token.

Or use the API:

```bash
curl -X POST "https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/credentials" \
  -H "Authorization: Bearer $NEON_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"scopes": ["ai_gateway:invoke"], "principal_type": "user"}'
```

**Using neon.ts?:**

If your project has a `neon.ts` file, declare `aiGateway: true` and run `neon deploy`. Credentials are provisioned and pulled into your local `.env` automatically, with no manual creation step. See [Authentication](/guides/ai-gateway-authentication) for details.

Store the credential as an environment variable:

```bash
export NEON_AI_GATEWAY_TOKEN=nt_live_...
```

## Find your branch host

Your branch's AI Gateway host is available in the Neon Console from the **Connect** dialog's **AI Gateway** tab, or via the Neon API. It follows this format:

```
br-<name>-api.ai.<cell>.<region>.aws.neon.tech
```

For example:

```bash
export NEON_AI_GATEWAY_BASE_URL=https://br-winter-pond-aptw82ef-api.ai.c-2.us-east-2.aws.neon.tech
```

This is different from your database connection string.

## Install dependencies

The quickstart uses the OpenAI SDK because the chat completions endpoint is OpenAI-compatible. It works with any model in the catalog, including GPT and Gemini.

**npm**

```bash
npm install openai dotenv
```

**yarn**

```bash
yarn add openai dotenv
```

**pnpm**

```bash
pnpm add openai dotenv
```

**pip**

```bash
pip install openai python-dotenv
```

## Make your first request

The chat completions endpoint is OpenAI-compatible. Set `baseURL` to your branch host and `apiKey` to your credential. No other changes needed.

**TypeScript**

```typescript
import OpenAI from 'openai';
import 'dotenv/config';

const client = new OpenAI({
  apiKey: process.env.NEON_AI_GATEWAY_TOKEN,
  baseURL: `${process.env.NEON_AI_GATEWAY_BASE_URL}/v1`,
});

const response = await client.chat.completions.create({
  model: 'gpt-5-mini',
  messages: [{ role: 'user', content: 'Hello!' }],
});

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

**Python**

```python
from openai import OpenAI
from dotenv import load_dotenv
import os

load_dotenv()

client = OpenAI(
    api_key=os.environ["NEON_AI_GATEWAY_TOKEN"],
    base_url=f"{os.environ['NEON_AI_GATEWAY_BASE_URL']}/v1",
)

response = client.chat.completions.create(
    model="gpt-5-mini",
    messages=[{"role": "user", "content": "Hello!"}],
)

print(response.choices[0].message.content)
```

**cURL**

```bash
curl -X POST "$NEON_AI_GATEWAY_BASE_URL/v1/chat/completions" \
  -H "Authorization: Bearer $NEON_AI_GATEWAY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5-mini",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'
```

## Stream a response

Add `stream: true` to receive a streamed response. Your existing streaming code works without changes. The gateway forwards `text/event-stream` responses from the upstream provider.

**TypeScript**

```typescript
import OpenAI from 'openai';
import 'dotenv/config';

const client = new OpenAI({
  apiKey: process.env.NEON_AI_GATEWAY_TOKEN,
  baseURL: `${process.env.NEON_AI_GATEWAY_BASE_URL}/v1`,
});

const stream = await client.chat.completions.create({
  model: 'gpt-5-mini',
  messages: [{ role: 'user', content: 'Write a haiku about serverless databases.' }],
  stream: true,
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? '');
}
```

**Python**

```python
from openai import OpenAI
from dotenv import load_dotenv
import os

load_dotenv()

client = OpenAI(
    api_key=os.environ["NEON_AI_GATEWAY_TOKEN"],
    base_url=f"{os.environ['NEON_AI_GATEWAY_BASE_URL']}/v1",
)

with client.chat.completions.create(
    model="gpt-5-mini",
    messages=[{"role": "user", "content": "Write a haiku about serverless databases."}],
    stream=True,
) as stream:
    for chunk in stream:
        print(chunk.choices[0].delta.content or "", end="", flush=True)
```

**cURL**

```bash
curl -X POST "$NEON_AI_GATEWAY_BASE_URL/v1/chat/completions" \
  -H "Authorization: Bearer $NEON_AI_GATEWAY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5-mini",
    "messages": [{"role": "user", "content": "Write a haiku about serverless databases."}],
    "stream": true
  }'
```

## Swap models

Change the `model` field to use a different provider. No other code changes required.

```typescript
// OpenAI
model: 'gpt-5-mini'

// Google
model: 'gemini-3-flash'

// Alibaba
model: 'qwen3-next-80b-a3b-instruct'
```

See [Models](/guides/ai-gateway-models) for the full list of available model IDs.

**Using the AI SDK?:**

For TypeScript apps and agents, use [`@neon/ai-sdk-provider`](https://www.npmjs.com/package/@neon/ai-sdk-provider) with the Vercel AI SDK. It reads `NEON_AI_GATEWAY_BASE_URL` and `NEON_AI_GATEWAY_TOKEN`, then routes each catalog model to the best AI Gateway endpoint for that provider.
