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

Use explicit structural separation like or tags, or use reasoning-specific models \(o1\) that handle Chain of Thought internally.

Journey Context:
The zero-shot CoT phrase was a breakthrough for GPT-3, but modern base models often treat it as a generic prelude rather than a true reasoning scaffold. It frequently leads to rambling, unstructured text that degrades code accuracy. Explicit structural tags force the model to populate a plan before generating the final answer, or native reasoning models handle it under the hood without polluting the output.
