[counterintuitive] Asking the model to 'think silently' or 'hide your reasoning' to save tokens or clean up output
Use native reasoning models that handle reasoning internally, or explicitly structure the CoT in the prompt and parse it out in code.
Journey Context:
Asking a model to 'think silently' in a standard chat completion doesn't actually make it think better; it just asks it to output text in a specific format. If you want hidden reasoning, you must use a reasoning-specific model or a multi-turn agent architecture where the reasoning happens in a separate API call. Asking it to 'hide' reasoning in a single turn often just truncates the reasoning, degrading the final answer.
