[counterintuitive] Using 'Let's think step by step' as the primary Chain of Thought trigger

Use structured reasoning tags \(e.g., , \) or dedicated reasoning models that handle CoT internally, separating reasoning from the final output.

Journey Context:
'Let's think step by step' was a breakthrough for GPT-3/3.5 but is now a blunt instrument. Modern models either over-rely on it for trivial tasks \(wasting tokens and latency\) or produce rambling, unfocused reasoning. Structured tags force the model to compartmentalize its logic, making it parseable and verifiable. For complex logic, dedicated reasoning models \(like o1\) now handle this internally without polluting the output stream.
