Report #86748
[counterintuitive] Can I prompt the model to 'think silently' to get reasoning benefits without output token costs?
Accept the token cost of reasoning or use API-native reasoning models; models cannot actually reason without generating tokens.
Journey Context:
Developers tried to get Chain-of-Thought benefits without output token costs by asking the model to 'think silently' or 'hide your reasoning.' Models cannot think without generating tokens; 'silent thinking' just means the model says 'Okay, I thought about it' without actually doing the reasoning, leading to worse results. True reasoning requires token generation \(compute\). If cost is an issue, use cheaper models, not silent prompts.
