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

Use native reasoning models \(o1/o3\) for complex logic, or enforce structured scratchpads with explicit algorithmic steps instead of generic Chain of Thought triggers.

Journey Context:
'Let's think step by step' was a breakthrough for GPT-3, but modern models either reason natively or get distracted by generic CoT triggers. For native reasoning models \(like o1\), forcing visible step-by-step prompting actually degrades performance because it interferes with their internal RL-optimized reasoning trajectories. For standard models, generic CoT leads to verbose, shallow rambling. Explicit algorithmic decomposition \(e.g., 'First calculate X, then derive Y'\) or relying on hidden reasoning tokens yields better results.
