Answer 1

from docs

OpenAI Environment Setup

By default, we use the OpenAI gpt-3.5-turbo model for text generation and text-embedding-ada-002 for retrieval and embeddings. In order to use this, you must have an OPENAI_API_KEY setup.

Local Environment Setup

If you don’t wish to use OpenAI, the environment will automatically fallback to using LlamaCPP and llama2-chat-13B for text generation and BAAI/bge-small-en for retrieval and embeddings. This models will all run locally.

In order to use LlamaCPP, follow the installation guide here. You’ll need to install the llama-cpp-python package, preferably compiled to support your GPU. This will use aronund 11.5GB of memory across the CPU and GPU.
