Self-Consistency

In depth

A decoding strategy that samples several chain-of-thought reasoning paths for the same question and returns the final answer that appears most often. It replaces a single greedy reasoning path with a majority vote, on the intuition that different valid lines of reasoning tend to converge on the correct answer. The original Google paper reported gains such as +17.9% on GSM8K over standard chain-of-thought prompting. Unlike best-of-N, it needs no separate verifier, only answers that can be compared.
