Installation

Model Gateway is available as a Docker image, which you can run on your local machine or deploy to a cloud provider.

Prerequisites

To get started, you will need to have Docker installed on your machine. If you don't have Docker installed, you can download it from the official Docker website.

Docker

Once you have Docker installed, you need to create a network for the Model Gateway:

docker network create modelgw

Model Gateway requires a PostgreSQL database to store its data. You can use the following command to start a PostgreSQL database in a Docker container:

docker run --detach --restart=always --network modelgw --name postgresql \
-e POSTGRES_USER=modelgw \
-e POSTGRES_PASSWORD=modelgw \
-e POSTGRES_DB=modelgw \
-p 5432:5432 \
postgres:16

Model Gateway is distributed as a Docker image, which you can pull from Docker Hub registry. To start the latest version of the Model Gateway image on your computer, run the following command:

# start the Model Gateway
docker run --detach --restart=always --network modelgw --name modelgw \
-e DATABASE_URL="postgresql://modelgw:modelgw@postgresql:5432/modelgw?schema=public" \
-e PRISMA_FIELD_ENCRYPTION_KEY="k1.aesgcm256.VYU1Jlyf1Yu9QGDVvVjgaf8QEP1SIhOReuiPBSbeyZA=" \
-e JWT_SECRET="jwtsecret" \
-e ADMIN_EMAIL="email@example.com" \
-e ADMIN_PASSWORD="password" \
-p 4000:4000 \
-p 4001:4001 \
modelgw/modelgw:latest

# start the Model Gateway Admin Console
docker run --detach --restart=always --network modelgw --name modelgw-admin \
-e GRAPHQL_URL=http://modelgw:4000/graphql \
-e NEXT_PUBLIC_GATEWAY_URL=http://localhost:4001 \
-p 3000:3000 \
modelgw/modelgw-admin:latest

After running the above commands, you can access the Model Gateway Admin Console at http://localhost:3000. Log in with the credentials you provided in the ADMIN_EMAIL and ADMIN_PASSWORD environment variables.

More information about the configured environment variables can be found in the Configuration section.

Docker Compose

You can also use Docker Compose to start the Model Gateway and the Admin Console. Create a docker-compose.yml file with the following content:

services:
  postgresql:
    image: postgres:16
    container_name: postgresql
    environment:
      POSTGRES_USER: modelgw
      POSTGRES_PASSWORD: modelgw
      POSTGRES_DB: modelgw
    ports:
      - "127.0.0.1:5432:5432"
    restart: always
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U modelgw"]
      interval: 5s
      timeout: 5s
      retries: 5

  modelgw:
    image: modelgw/modelgw:latest
    platform: linux/amd64
    container_name: modelgw
    environment:
      DATABASE_URL: "postgresql://modelgw:modelgw@postgresql:5432/modelgw?schema=public"
      PRISMA_FIELD_ENCRYPTION_KEY: "k1.aesgcm256.VYU1Jlyf1Yu9QGDVvVjgaf8QEP1SIhOReuiPBSbeyZA="
      JWT_SECRET: "jwtsecret"
      ADMIN_EMAIL: "<your email>"
      ADMIN_PASSWORD: "<your password>"
    ports:
      - "127.0.0.1:4000:4000"
      - "127.0.0.1:4001:4001"
    restart: always
    depends_on:
      postgresql:
        condition: service_healthy

  modelgw-admin:
    image: modelgw/admin:latest
    platform: linux/amd64
    container_name: modelgw-admin
    environment:
      GRAPHQL_URL: http://modelgw:4000/graphql
      NEXT_PUBLIC_GATEWAY_URL: http://localhost:4001
    ports:
      - "127.0.0.1:3000:3000"
    restart: always
    depends_on:
      - modelgw

Then run the following command to start the database, Model Gateway and Admin Console:

docker-compose up -d

Making your first API request

Now that you have Model Gateway up and running, let's make your first API request to the inference endpoint. The inference endpoint is where you send your AI inference requests. In this example, we'll use the cURL command-line tool to make a request to the inference endpoint.

curl -v -X POST http://localhost:4001/ \
  -H "Authorization: Bearer we-dont-have-any-yet" \
  -H "Content-Type: application/json"

You should receive an error response with the message 401 Unauthorized. This is because you need to provide a valid API key in the Authorization header to authenticate your request.

HTTP/1.1 401 Unauthorized
Content-Type: application/json; charset=utf-8

{
  "error": {
    "message": "Incorrect Model Gateway API key provided",
    "type": "invalid_request_error",
    "param": null,
    "code": "invalid_api_key"
  }
}

What's next?

Great, you're now set up and have made your first request to the API. Here are a few links that might be handy as you venture further into the Model Gateway:
