[counterintuitive] Using prompt tricks like 'Think inside tags but only show the final answer' to hide reasoning

Allow the reasoning to be visible in the output stream, or use a dedicated reasoning model \(like o1\) that handles the thought process natively and securely.

Journey Context:
Developers want the benefits of Chain of Thought without exposing the internal logic or paying output token costs. However, instructing the model to 'think silently' often results in the model skipping the reasoning step entirely and jumping to the answer, severely degrading output quality. If hidden reasoning is strictly required for security/IP, use an API-level reasoning model where the CoT is hidden by the system architecture, not by prompt hacking.
