Self-Consistency

What Self-Consistency is

Because sampling is stochastic, a model can reach the right answer by different routes. Agreement across routes is a useful proxy for correctness.

How it works

Generate n completions at non-zero temperature, extract the final answers, and pick the majority. Cost scales linearly with n, so it is reserved for high-value questions.

Why it matters

It is one of the simplest reliability upgrades available for reasoning tasks and needs no model changes.
