Report #51652

[counterintuitive] Telling the model 'Do not output your reasoning, just give the final answer' saves tokens without hurting accuracy

Allow the model to output reasoning in structured tags \(e.g., \) before the final answer; suppress only if strictly necessary for UX, but accept the accuracy penalty.

Journey Context:
Developers often want clean UIs and try to prompt the model to 'think silently' or 'only output the JSON'. This breaks the model's ability to perform implicit Chain of Thought. If you force it to output the answer immediately, it loses the compute time \(tokens generated\) needed to work through the problem. Use structured tags or native reasoning models instead of suppressing thought entirely.
