[counterintuitive] Instructing the model to 'think silently' or 'hide your chain of thought' while still expecting high reasoning quality

Allow the model to output its reasoning via designated tags \(e.g., \), or use models with native hidden reasoning. Parse out the final answer from the tags.

Journey Context:
Developers wanted clean output without the thought process cluttering the UI. However, suppressing the CoT degrades the model's reasoning ability because autoregressive generation is the computation. You can't have the model 'think' without generating the tokens \(unless using specialized reasoning models\). If you need clean output, instruct the model to put reasoning in tags and parse the output after the closing tag.
