I would ask myself what am I actually paying for here. -- as mentioned in other comments, they could always have a peer next to them during a call, so hallucinations won't do --
+ Using AI is actually cheating or being productive for the role?
+ Am I worried that they'll do all their job in 5 minutes and afterwards do something else?
Maybe you are worried about them not being able to actually do the job, which probably means the interview process was wrong from the start. Alternatively, the performance expectations may be higher for the role; e.g. what before was 1x now needs to be 5x productivity.
As an alternative, I've heard of many SMBs opting for a model in which the last bit of the hiring process includes some paid work for a week to see how they actually perform, or checking references in depth.
