if you're referring to https://youtu.be/GcqQ1ebBqkc?t=1027 he doesn't actually say that each model has been profitable.

He says "You paid $100 million and then it made $200 million of revenue. There's some cost to inference with the model, but let's just assume in this cartoonish cartoon example that even if you add those two up, you're kind of in a good state. So, if every model was a company, the model is actually, in this example is actually profitable. What's going on is that at the same time"

notice those are hypothetical numbers and he just asks you to assume that inference is (sufficiently) profitable.

He doesn't actually say they made money by the EoL of some model.
