You are definitely allowed to train other models with these models, you just have to give credit in the name, per the license:

> If you use the Llama Materials or any outputs or results of the Llama Materials to create, train, fine tune, or otherwise improve an AI model, which is distributed or made available, you shall also include “Llama” at the beginning of any such AI model name.

Indeed, this is something they changed in the 3.1 version of the license.

Regardless, the license [1] still has many restrictions, such as the acceptable use policy [2].
