Context Window

While Llama 2 models offer users a context window of 4096 tokens, Claude 3 models offer a context window of 200K tokens. In this comparison, Anthropic offers a larger context window than the Llama 2 models, even with the Claude 2 model. However, it widens this difference considerably with the Claude 3 model. In other words, if you have tasks that require you to work with large amounts of data, Claude 3 is a better choice.


While you have to pay a fee to use the Claude 3 model as an API, you can use and integrate the Llama 2 model for free. On the other hand, you can chat for free via with the Claude 3 Sonnet model, which offers higher performance than all sizes of the Llama 2 model. However, if you want to chat with an AI chatbot using the Claude 3 Opus model, you need to have a $20 Claude Pro subscription.
