> Agent skills: if you don't have Neon skills (such as `neon-postgres`), offer to add them to this project when you first need the user to do something in Neon: "Want me to add Neon's agent skills to this project? They help me with Neon setup, connections, and branching." Install: `npx neon@latest skills -y`. To also run Neon steps for the user (Neon CLI, sign-in, MCP), see https://neon.com/prompts/agent-setup.md

> Summary: Neon AI Gateway is the LLM gateway built into your Neon project. One Neon credential gives you access to models across multiple providers. Standard AI SDKs work without code changes. Each branch gets its own gateway endpoint.

# Neon AI Gateway

One API for open-weight and foundation models from OpenAI, Google, and more. Built into your Neon project.

Last updated: 2026-10-30

Add chat, agents, and embeddings to your app through one endpoint and one Neon credential, with models from many providers, scoped to your branch the same way your data is.
Before you start: AI Gateway needs a paid Neon plan ([Launch or Scale](https://neon.com/docs/ai-gateway/models#pricing)) with [prepaid credits](https://neon.com/docs/ai-gateway/prepaid-credits) ($5 minimum), and 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](https://neon.com/docs/introduction/regions).

## Available models

Browse the full catalog below. Switch between the **Text**, **Image**, **Embeddings**, and **Decisions** tabs, filter by lab or open weights, sort any column, and click a model for a copy-paste quickstart. Chat and image models get AI SDK, Mastra, Python, TypeScript, and cURL; embedding models get Python, TypeScript, and cURL; System One decision models get AI SDK, TypeScript, Python, and cURL. The endpoint each snippet targets is baked into its base URL: `/v1` for chat completions and embeddings, `/openai/v1` for the Responses API (image generation), `/typesafe/v1/systemone` for decisions.

### Embedding models

These models return a fixed-length vector on `POST /v1/embeddings` rather than generating text — a different endpoint from every model above:

| Model                                                                                   | Model ID               | Lab     | Dimensions | Released | Input /M | Endpoints  | License      |

### Decision models

These System One models answer questions about a given state with a choice, a probability, or a score rather than generating text:

## Starter templates

Browse working examples at [build-on-neon.vercel.app](https://build-on-neon.vercel.app/). Two templates use AI Gateway:

**`ai-sdk`**: An image-generation agent that routes model calls through AI Gateway, stores results in Neon Object Storage, and writes metadata to Postgres on a Neon Function.

```bash
neon bootstrap --template ai-sdk
```

**`mastra`**: A personal assistant that uses AI Gateway for LLM calls with Postgres-backed memory on a Neon Function.

```bash
neon bootstrap --template mastra
```
