The code looks mostly correct but could be optimized:

• Adding models in reverse order can improve performance by reducing the need to iterate over the entire list each time you append a new model.

Here's an updated version of the code with this optimization suggestion:

# Assuming model_info_list is sorted from most recent to oldest

model_info = (
    .append_default_model_info(model_info_list[0])
    .append_default_model_info(model_info_list[1])
    .append_default_model_info(model_info_list[2])
    .append_default_model_info(model_info_list[3])
    .append_default_model_info(model_info_list[4])

    .build()
)

This way, when append_default_model_info is called without specifying which index, it will append items starting from the first position (model_info_list[0]) towards the end, potentially improving execution speed slightly if subsequent appends are added after sorting the list initially.
