The Rise of Llama 2 and the Evolution of AI Language Models

TLDRLlama 2, a new language model released by Meta in collaboration with Microsoft, offers a commercial license and 70 billion parameters. Comparisons with GPT-4 and Google's generative AI tool show distinct strengths in each. Llama 2's verbosity and well-written responses make it valuable, but Poetry from OpenAI's GPT-4 is more poetic in nature. When it comes to coding, Llama 2 falls short. However, it is likely the best option among open source models. Safety is a key consideration in Llama 2, using reinforcement learning from human feedback to prevent undesirable outputs.
