[counterintuitive] Asking the model to 'Think silently' or 'Think to yourself' to save output tokens while retaining reasoning

Explicitly structure the Chain of Thought in the prompt \(e.g., using tags\) and parse it out, or use a native reasoning model \(like o1\) that handles it internally.

Journey Context:
Developers often try to get the benefits of CoT without the token cost by saying 'think silently'. Models often skip the reasoning or produce degraded reasoning when asked to hide it. If you need reasoning, you must allocate the output tokens for it or use a model specifically architected to reason internally. You cannot cheat the token cost of inference.
