 ### Docker Model Provider
 
 In the `compose.yaml` file, the `llm` service will route requests to the LLM API model using a [Docker Model Provider](https://docs.defang.io/docs/concepts/managed-llms/openai-access-gateway#docker-model-provider-services).

-The OpenAI-compatible managed LLM feature, provided by the Defang OpenAI Access Gateway, allows users to use AWS Bedrock or Google Cloud Vertex AI with an OpenAI compatible SDK. This enables switching from OpenAI to one of these cloud-native platforms without modifying your application code.
+Using the [Defang OpenAI Access Gateway](#defang-openai-access-gateway), the feature `x-defang-llm: true` enables you to use Managed LLMs on the Defang Playground or on platforms offered by BYOC providers (such as AWS Bedrock or GCP Vertex AI) with an OpenAI-compatible SDK.

 You can configure the `MODEL` and `ENDPOINT_URL` for the LLM separately for local development and production environments.
 * The `MODEL` is the LLM Model ID you are using.
 * The `ENDPOINT_URL` is the bridge that provides authenticated access to the LLM model.
