[counterintuitive] Asking the model to 'think silently' or 'hide your reasoning' in standard text generation

Use native API features for hidden reasoning \(like reasoning tokens in o1\) or explicitly structure the output to separate reasoning from the final answer using XML tags, accepting that the reasoning must be generated to exist.

Journey Context:
Models cannot actually 'think silently' in a standard text completion; if they don't output the tokens, the computation doesn't happen. Asking them to 'think but don't output' often results in skipped reasoning. Newer models have native hidden reasoning, but for standard models, you must output the reasoning to get the benefit.
