Chain of Thought

Master transparent, step-by-step reasoning for more accurate and explainable AI agents

Common CoT Patterns

There are several established patterns for implementing chain-of-thought reasoning, each with different trade-offs. The right approach depends on your problem complexity, token budget, and accuracy requirements.

Zero-Shot CoT

Simply add "Let's think step by step" to your prompt

Example Prompt:
Problem: What is 15% of 240?

Let's think step by step:
AI Response:
Step 1: Convert percentage to decimal: 15% = 0.15

Step 2: Multiply: 0.15 × 240

Step 3: Calculate: 0.15 × 240 = 36

Answer: 36
✓ Advantages:
  • Simple to implement
  • No examples needed
  • Works on many problems
  • Low token cost
⚠ Limitations:
  • Less guidance
  • Quality varies
  • May skip important steps

Decision Guide: Which Pattern to Use?

🚀

Use Zero-Shot CoT When:

  • • Quick prototyping or testing
  • • Simple, well-defined problems
  • • Token budget is limited
  • • You don't have example chains to provide
🎯

Use Few-Shot CoT When:

  • • Accuracy is critical
  • • You have high-quality example chains
  • • Problem domain is specific/technical
  • • You need consistent formatting
🧩

Use Least-to-Most When:

  • • Problem is very complex/multi-step
  • • Subproblems can be solved independently
  • • Building solutions incrementally makes sense
  • • You need to parallelize sub-tasks

Advanced Techniques

🔄 Self-Consistency
Generate multiple reasoning chains for the same problem, then pick the most common answer. Dramatically improves accuracy (but uses more tokens).
🔍 Chain Verification
After generating a chain, ask the model to verify each step for logical consistency and catch errors.
🌳 Tree of Thoughts
Explore multiple reasoning paths simultaneously (like a search tree), then select the best branch. Great for creative or open-ended problems.
