[counterintuitive] Instructing the model to 'think silently' or hide its reasoning to save output tokens

Allow the model to output its reasoning in a designated structured format \(like \) or use API-level reasoning tokens, but do not instruct it to suppress reasoning.

Journey Context:
Instructing a model to 'think silently' often degrades its reasoning. The model tries to compress its CoT to avoid outputting it, leading to logical errors. If you need to save tokens, use the API's native reasoning token features \(like o1's reasoning effort\) or explicitly parse out a visible scratchpad. Trying to force a chat model to 'not output' its thoughts breaks the alignment between generation and reasoning.
