[counterintuitive] Instructing the model to 'think silently' or hide its reasoning in standard chat models

Use native reasoning models \(o1, o3-mini\) or structured output with a hidden reasoning field if you need to separate thought from answer.

Journey Context:
Developers used to write prompts like 'First think step by step in a tag, then output the final answer.' Standard chat models are not trained to actually reason better just because you put a scratchpad tag; they just generate text that looks like reasoning. If you need hidden reasoning, you must use models architected for it \(like o1\) or explicitly parse the intermediate output yourself. Pretending the model is silently thinking just obscures its actual computation.
