[counterintuitive] Using 'Let's think step by step' to force reasoning in modern models

Use structured reasoning frameworks or native reasoning models; replace generic Chain-of-Thought triggers with domain-specific decomposition \(e.g., '1. Identify constraints, 2. Draft pseudocode, 3. Implement'\).

Journey Context:
'Let's think step by step' was a breakthrough for GPT-3, but modern instruction-tuned models already reason implicitly. Generic CoT triggers now cause bloated, token-wasting outputs that often hallucinate intermediate steps just to fill the 'thinking' requirement. For models with native reasoning \(o1\), explicit CoT prompts interfere with their internal optimization. For standard models, structured, task-specific reasoning steps yield better results than a generic 'think step by step' instruction.
