Three supervisors rewrote model risk guidance. Not one wrote a new rule for AI.
They didn't need to — an AI model is a model. SR 26-2, SS1/23 and OSFI E-23 reach the same question from three different directions: who validated this, independently of whoever built it? Brief #006 puts all three side by side, dated and sourced. Including the one artefact we ask for before we look at the model at all.
If your AI models sit outside your model inventory, that isn't an AI gap. It's a model risk gap — and it has been findable for years.
