It’s a risk if your model can’t accurately predict user responses, but I don’t see how it’s a necessary characteristic of the approach. If so the same issue would apply to model based RL in general no? Unless you are suggesting something special about language modelling or user responses which makes it fundamentally hard to learn a model of.
Wouldn’t this just constitute to the model sort of overfitting to noise?
