+# OpenAI Access Gateway
 
-Defang makes it easy to deploy on your favourite cloud's managed LLM service with our [OpenAI Access Gateway](https://github.com/DefangLabs/openai-access-gateway). This service sits between your application and the cloud service and acts as a compatibility layer. It handles incoming OpenAI requests, translates those requests to the appropriate cloud-native API, handles the native response, and re-constructs an OpenAI-compatible response.

 See [our tutorial](/docs/tutorials/deploying-openai-apps-aws-bedrock-gcp-vertex/) which describes how to configure the OpenAI Access Gateway for your application
 
+## Docker Provider Services
+
+As of Docker Compose v2.35 and Docker Desktop v4.41, Compose introduces a new service type called `provider` that allows you to declare platform capabilities required by your application.
+For AI models, you use the `model` type to declare model dependencies. This will expose an OpenAI compatible API for your service. Check the [Docker Model Runner documentation](https://docs.docker.com/compose/how-tos/model-runner/) for more details.
+
+```yaml
+services:
+  chat:
+    build: .
+    depends_on:
+      - ai_runner
+
+  ai_runner:
+    provider:
+      type: model
+      options:
+        model: ai/mistral
+    x-defang-llm: true
+```
+
+Under the hood, when you use the `model` provider, Defang will deploy the **OpenAI Access Gateway** in a private network. This allows you to use the same code for both local development and cloud deployment.
+The `x-defang-llm` extension is used to configure the appropriate roles and permissions for your service. See the [Managed Language Models](/docs/concepts/managed-llms/managed-language-models/) page for more details.
