Tree of Thought

What Tree of Thought is

Where chain-of-thought walks a single path, tree-of-thought treats reasoning as search over partial solutions with explicit evaluation at each step.

How it works

The model proposes candidate next steps, scores them, expands the promising branches and prunes the rest, guided by breadth-first or best-first search.

Why it matters

It helps on puzzles and planning problems where the first plausible step is often wrong, at a significant cost in tokens.
