Meta released Llama 2 in the summer of 2023. The new version of Llama is fine-tuned with 40% more tokens than the original Llama model, doubling its context length and significantly outperforming other open-sourced models available. The fastest and easiest way to access Llama 2 is via an API through an online platform. However, if you want the best experience, installing and loading Llama 2 directly on your computer is best.
