AzureConfig(**kwargs)

Bases: OpenAIGPTConfig

Configuration for Azure OpenAI GPT.

Attributes:

Name	Type	Description
type	str	should be azure.
api_version	str	can be set in the .env file as AZURE_OPENAI_API_VERSION.
deployment_name	str	can be set in the .env file as AZURE_OPENAI_DEPLOYMENT_NAME and should be based the custom name you chose for your deployment when you deployed a model.
model_name	str	can be set in the .env file as AZURE_GPT_MODEL_NAME and should be based on the model name chosen during setup.
model_version	str	can be set in the .env file as AZURE_OPENAI_MODEL_VERSION and should be based on the model name chosen during setup.

set_chat_model()

Sets the chat model configuration based on the model name specified in the .env. This function checks the model_name in the configuration and sets the appropriate chat model in the config.chat_model. It supports handling for '35-turbo' and 'gpt-4' models. For 'gpt-4', it further delegates the handling to handle_gpt4_model method. If the model name does not match any predefined models, it defaults to OpenAIChatModel.GPT4.
