Chain-of-Thought and Self-Consistency: Advanced AI Reasoning

This article is written in English. Our training modules are available in multiple languages.

LLMs are powerful but they think in shortcuts. When asked a complex question, they often jump to an answer without showing — or performing — the intermediate reasoning steps. Chain-of-Thought (CoT) prompting forces the model to think step by step, and Self-Consistency takes this further by running multiple reasoning paths and picking the best answer.

Why Models Need Help Reasoning

LLMs predict the next token — they do not "reason" in the human sense. For simple questions, direct prediction works fine. But for multi-step problems (math, logic, analysis), the model needs to lay out intermediate steps to arrive at the correct answer.

Think of it this way: if someone asks you "What is 47 times 83?", you do not instantly produce "3,901." You decompose: 47 times 80 = 3,760, plus 47 times 3 = 141, total = 3,901. Chain-of-Thought forces the model to decompose in the same way.
