Question: replacing the Llama 2 7b chat component with an equivalent Code Llama 7b

[VovaTch]

Hi, I'm interested in creating a model that can perform image->code inference on it. Is the Llama2 chat interchangeable? Is it possible to just plug-and-play Code Llama 7b to get decent results, or do I have to fine-tune it somehow? And if plugging in Code Llama 7b is possible, is it also possible to plug in the larger versions?
