Day 38/42: What Is RLAIF?

Yesterday, we talked about preference tuning.
But humans don’t scale.

RLAIF means Reinforcement Learning from AI Feedback.

Instead of humans ranking answers,
a stronger model does the judging.

Faster.
Cheaper.
More consistent.

It’s how top models teach the next generation.

But bias can propagate too.
So humans still matter.

Missed Day 37? Watch it first.
Tomorrow, we reward correctness directly: RLVR.
