[counterintuitive] Asking standard chat models to think silently inside hidden tags to save output tokens

Allow the model to output its reasoning, or use a dedicated reasoning model \(like o1\) that handles internal reasoning natively.

Journey Context:
Developers want CoT benefits without token cost. But standard LLMs are autoregressive; they need to emit the tokens to compute the next state. Telling a standard model to 'think but don't output' is fundamentally at odds with autoregressive generation and degrades the final answer quality. Reasoning models are specifically architected with hidden reasoning states; standard models are not.
