By default, we use the OpenAI GPT-3
text-davinci-003 model. In order to use this, you must have an OPENAI_API_KEY setup.
You can register an API key by logging into OpenAI’s page and creating a new API token.
You can customize the underlying LLM in the Custom LLMs How-To (courtesy of Langchain). You may need additional environment keys + tokens setup depending on the LLM provider.
