All three currently available Llama 2 model sizes 7B 13B 70B are trained on 2 trillion tokens and have double the context length of Llama 1. Increasing context length is not as simple as feeding the model with longer sequences. LLaMA-2 has a context length of 4K tokens To extend it to 32K context three things need. The model has been trained to handle context lengths up to 32K which is a significant improvement over the previous versions. Llama 2 supports a context length of 4096 twice the length of its predecessor The training process described is very similar to Llama 1..
