"\n",

"This examples demonstrates how to generate text embeddings using the GraphRAG LLM library with Azure OpenAI's embedding service. It loads API credentials from environment variables, creates a ModelConfig for the Azure embedding model and configures authentication to use either API key or Azure Managed Identity. The script then creates an embedding client and processes a batch of two text strings (\"Hello world\" and \"How are you?\") to generate their vector embeddings."
