Auto-CoT (Automatic Chain of Thought) — AI Glossary

Auto-CoT is a method for generating chain-of-thought demonstrations automatically rather than hand-writing them. The pipeline embeds a pool of candidate questions, clusters them by similarity, selects one representative question per cluster, and prompts the model with "Let's think step by step" to produce a reasoning trace for each representative. The resulting question-reasoning pairs become few-shot demonstrations.
