Report #64530
[counterintuitive] Appending 'Let's think step by step' to force reasoning
Use structured reasoning tags \(e.g., \) or native reasoning models \(e.g., o1\) and explicitly instruct the model to decompose the problem according to a specific logical framework.
Journey Context:
'Let's think step by step' was a breakthrough for GPT-3, but for modern models, it is a blunt instrument that often leads to rambling, unfocused, or biased reasoning where the model simply post-hoc justifies its pre-existing answer. Modern models benefit from structured, isolated reasoning environments where the computation is separated from the final output, preventing the explanation from anchoring the conclusion.
