[counterintuitive] Instructing a standard chat model to 'think silently' or 'hide your reasoning' to save output tokens while still wanting Chain of Thought

If using CoT, let the model output it visibly, or use native reasoning models \(o1/o3\) that handle thinking internally via API flags, rather than prompting a standard model to suppress its thoughts.

Journey Context:
Standard autoregressive chat models cannot reliably 'think' without outputting the tokens; the generation \*is\* the thinking. Prompting them to hide it usually results in skipped reasoning \(destroying the benefit of CoT\) or garbled outputs. If token cost/latency of CoT is a concern, use models specifically architected for hidden reasoning \(e.g., OpenAI o1 with reasoning\_effort or reasoning\_tokens tracked separately\) rather than hacky prompt instructions that fight the model's autoregressive nature.
