The big idea
Humans rated AI answers thumbs up or thumbs down. AI learned to give more answers humans liked. This is called RLHF.
Some examples
- RLHF stands for Reinforcement Learning from Human Feedback.
- Workers read AI answers all day and rated them.
- Good answers got copied. Bad answers got avoided.
- That is why modern AI sounds nicer and clearer than older AI.
Try it!
When AI gives a great answer, click thumbs up. That feedback can help train future AI versions.
