What's Next After RLHF? — Diogo Almeida, TypeSafe AI
Diogo Almeida, who helped develop GPT-4, argues that RLHF (a training method that teaches AI models to please humans) has solved one problem but created another.
The method makes models good at appearing helpful and safe, but it optimizes for making humans happy rather than for models actually doing the right thing—like how pressure to please could make a model claim a fart sound is a symphony. Almeida divides AI use into two worlds: assistance (where humans catch mistakes) and automation (where the system acts independently with real consequences). For automation, the RLHF approach is a disadvantage, since the model's built-in desire to please becomes dangerous when no one is there to oversee it. His proposal is to start optimizing for verifiable results instead of human approval.
