[counterintuitive] Instructing the model to 'think silently' or 'output only the final answer' to save tokens while expecting high reasoning quality

Allow the model to output its reasoning in designated tags \(e.g., \`\`\) and strip them programmatically in post-processing, or use models with hidden reasoning tokens.

Journey Context:
Developers often try to save costs/latency by suppressing Chain-of-Thought output. However, LLMs are autoregressive; they \*need\* to generate intermediate tokens to perform computation. Suppressing the output suppresses the reasoning capability itself, leading to drastically worse logic and hallucination. If token cost is an issue, use a cheaper model or parse out the final answer from a structured scratchpad.
