The Alignment Engine

The framework lets a model create a tree of possibilities. At each step it generates, evaluates and searches — much closer to how people actually think.

It can abandon low-scoring branches and backtrack to a more promising one, navigating the tree efficiently.

Reinforcement Learning from Human Feedback became the industry’s standard method for this task, shaping responses to be helpful, honest and safe.
