Azure AI model inference for LLM.

from llama_index.llms.azure_inference import AzureAICompletionsModel

llm = AzureAICompletionsModel(
    endpoint="https://[your-endpoint].inference.ai.azure.com",

# If using Microsoft Entra ID authentication, you can create the
# client as follows:
#
# from azure.identity import DefaultAzureCredential
#
# llm = AzureAICompletionsModel(
#     endpoint="https://[your-endpoint].inference.ai.azure.com",
#     credential=DefaultAzureCredential()
# )
#
# # If you plan to use asynchronous calling, make sure to use the async
# # credentials as follows:
#
# from azure.identity.aio import DefaultAzureCredential as DefaultAzureCredentialAsync
#
# llm = AzureAICompletionsModel(
#     endpoint="https://[your-endpoint].inference.ai.azure.com",
#     credential=DefaultAzureCredentialAsync()
# )

resp = llm.chat(

# Once the client is instantiated, you can set the context to use the model
