My idea is that the end user is an employee, not a customer of the company. Since they have a general understanding and the questions won't be as broad, i hope one of the open models with a less strict license is enough for the task. Stability AI released a model with creative commons CC BY license (allows commercial use with attribuition, although Creative Commons is a weird license for a gigantic database) and there are some "LLaMA" clones (open llama, redpanda, vicuna, etc.) that i need to look deeper into to understand how it was done and how it didn't inherit the original's license
