A long time ago, I wrote a short story about a military AI that had the power to launch warheads, but needed to first justify its decisions to a second AI whose entire purpose was to act as checks-and-balances for the first. Can't we do something similar with these models? The output of the main model is fed into a second model (to which the end users have no access) trained on determining what can and cannot be exposed to the end user. If the second model answers in the negative, the main model just provides a canned decline message to the end user. Perhaps there are other ways to cluster or chain LLMs.
