[counterintuitive] Asking the model to 'think silently' or hide its chain-of-thought in hidden tags to save output tokens

Allow the model to output its reasoning visibly, or use dedicated reasoning models that handle internal reasoning natively. Do not suppress CoT.

Journey Context:
Developers used to ask models to think in tags and output in tags to save tokens or hide messy reasoning. However, suppressing CoT often degrades the quality of the final answer because the model relies on the act of generating the reasoning to arrive at the correct conclusion. If token cost is an issue, use a cheaper model for the reasoning step or a dedicated reasoning model.
