Mark Sewards

My hon. Friend tempts me to say something I am not allowed to in this place, so I will say that they absolutely would prefer me—of course they would. AI Mark could also be exploited to say things that just were not true. So I lifted the guardrails to reduce the risk before I released him to the public, but this made him significantly less useful. He only responded to key phrases and he stuck to the content that I had fed him, but that made it so much harder to distinguish him from a normal chatbot. Usefulness and safety will clearly be a balancing act as this technology develops. We know AI can be dangerous—we have heard the arguments today—but we have also seen its potential. I have seen its potential. If we want systems that are both safe and useful, businesses need the space to experiment, and I ask the Minister in his summing-up to confirm the Government’s current approach to this. Now, I am not arguing for a free-for-all; to be clear, we need proportionate regulation and effective oversight. That much is obvious. I will just say that AI Mark did not actually save me any time. I read the thousands of transcripts that came through—I read them all myself; I did not delegate that to anyone else, and it created far more work for me. I could have refined this model to operate well within the guardrails I had set for him, but I was not willing to ask my team to put aside time to refine it when we had real casework to deal with immediately. That is why I took the decision this month to shut AI Mark down. There is space for a business to take up the baton and take this forward, because the technology is incredible and the potential is real, but that is all it is for now—potential. I will just finish with this: one person from Ukraine, or at least a Ukrainian IP address, tried to get AI Mark to declare support for repressive regimes. Because of the guardrails that we put in place, he did hold firm in his love for democracy, just as I am sure that everyone else here would.
