[counterintuitive] Can I force the model to think silently using hidden scratchpad tags to save output tokens?

Allow the model to reason in standard prose before answering, or use models with native hidden reasoning \(like o1\). Forcing arbitrary scratchpad tags on standard models degrades logic.

Journey Context:
Developers tried to hack hidden Chain of Thought by asking models to think in XML tags and then only output the last part. However, standard models aren't RLHF'd to separate reasoning from output this way reliably; they often leak logic or produce worse answers because the intermediate reasoning steps aren't properly conditioned. Models like o1 handle this natively. For standard models, it's better to just ask for the reasoning and the answer, then parse the answer programmatically.
