Predictable as in, can say in advance what it will do.

Repeatable means you get the same output a second time, given the same input. Predictable means you can say in advance what it will do, and can then check the output against your prediction.

If you can't predict the outcome, you can't validate the process, and can't guarantee its performance.

That much is clear but any remotely continuous AI model is very predictable.
