Day 39/42: What Is RLVR?

Yesterday, we used opinions.
Today, we use facts.

RLVR means Reinforcement Learning from Verifiable Rewards.

The model gets rewarded only if:
the code passes tests,
the math checks out,
the answer matches evidence.

No vibes.
No preferences.
Just correctness.

This works best when truth can be checked.

Missed Day 38? Start there.
Tomorrow, we use randomness to improve answers: self-consistency.
