And I'm thinking how I can update its knowledge without doing a full training. Unfortunately, I don't have access to several A100 cards.

One way I came up is let it tell me what it need using prompt. Something like this:

[User]: What time is it?
[LLaMa]: [Request] current time
[System]: 2023-07-27T08:00:29
[LLaMa]: [Answer] Now is 8 AM.

But it seems like LLaMa did not have enough logic power to make request of what it needs to finish the task. I don't know if it's my prompt not good enough, or it's just simply not possible to do it.
