Llama 2 vs ChatGPT

The next generation of our open source large language model

This release includes model weights and starting code for pretrained and fine-tuned Llama language models — ranging from 7B to 70B parameters.

Llama 2 was trained on 40% more data than Llama 1, and has double the context length.

Training Llama-2-chat: Llama 2 is pretrained using publicly available online data. An initial version of Llama-2-chat is then created through the use of supervised fine-tuning. Next, Llama-2-chat is iteratively refined using Reinforcement Learning from Human Feedback (RLHF), which includes rejection sampling and proximal policy optimization (PPO).

ChatGPT is a tool that helps optimize language models for dialogue. It uses advanced algorithms and techniques to analyze and understand how people communicate, providing recommendations and suggestions to help improve the effectiveness of language models in dialogue situations. Whether you're a developer, a researcher, or anyone else who is interested in improving the performance of language models in dialogue situations, ChatGPT is a valuable resource to help you achieve your goals. If you want to optimize language models for dialogue and improve their performance, ChatGPT is a tool to consider.
