## Definition
Self-Consistency Prompting is a reasoning strategy where a model generates multiple independent thinking paths for a prompt, and the system selects the most common final answer using majority voting.

## Architectural Mechanics & Deep Dive
Self-Consistency Prompting is a prompting technique that improves reasoning performance by generating multiple independent paths of Chain of Thought reasoning for a single prompt. The final response is determined by taking a majority vote over all the generated answers, filtering out individual calculation errors or random hallucinations.

## Industry Applications & Real-World Use Cases
Logic puzzles solving, coding bug fixes, and mathematics benchmarking

## Frequently Asked Questions

### How does Self-Consistency improve reasoning?
By sampling multiple reasoning paths, it washes out random calculation errors or hallucination points that might occur in a single run.

### Does it increase API cost?
Yes, it scales costs linearly because the model must generate N separate responses for a single query.
