You can self-host it as well.

I wouldn't use "bias" here. It's a very ambiguous term in machine learning.

Not sure what a better term would be... Just being more specific might help, like "bias in the training data"?

But what does that mean? That the training distribution isn't representative of the population distribution, i.e. that it wasn't sampled IID? But the professors look pretty representative of real professors to me, so this doesn't sound very likely.
