DESCRIPTION:
This sample demonstrates how to get a chat completions response from
the service using a synchronous client. The sample also shows how to
set default chat completions configuration in the client constructor,
which will be applied to all `complete` calls to the service.
This sample assumes the AI model is hosted on a Serverless API or
Managed Compute endpoint. For GitHub Models or Azure OpenAI endpoints,
the client constructor needs to be modified. See package documentation:
https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/ai/azure-ai-inference/README.md#key-concepts
USAGE:
python sample_chat_completions_with_defaults.py
Set these two environment variables before running the sample:
1) AZURE_AI_CHAT_ENDPOINT - Your endpoint URL, in the form
https://<your-deployment-name>.<your-azure-region>.models.ai.azure.com
where `your-deployment-name` is your unique AI Model deployment name, and
`your-azure-region` is the Azure region where your model is deployed.
2) AZURE_AI_CHAT_KEY - Your model key. Keep it secret.
