[counterintuitive] Instructing the model to 'think silently' or 'do not output your reasoning' to save output token costs

Allow the model to output its reasoning trace, or use a dedicated reasoning model \(e.g., o1\) that handles computation internally. Never suppress the text output of a standard LLM's reasoning.

Journey Context:
Developers often try to get the benefits of Chain-of-Thought without paying the token cost. However, LLMs are autoregressive—the text output \*is\* the computation. Suppressing the output suppresses the reasoning, leading to drastically worse answers. If token cost is a concern, use a smaller model, use a native reasoning model with hidden tokens, or optimize the prompt so it requires fewer steps.
