How to Build a Chatbot Using Streamlit and Llama 2

Llama 2 is an open-source large language model (LLM) developed by Meta. It is a competent open-source large language model, arguably better than some closed models like GPT-3.5 and PaLM 2. It consists of three pre-trained and fine-tuned generative text model sizes, including the 7 billion, 13 billion, and 70 billion parameter models.
