Report #61275

[counterintuitive] Prompting 'Think step by step but only output the final answer' to save tokens

Allow the model to output intermediate reasoning, or use native extended thinking/reasoning features that separate thought from output.

Journey Context:
Developers tried to get the benefits of CoT without cluttering the UI or wasting output tokens. However, forcing the model to suppress its reasoning in the output stream degrades the quality of the reasoning itself \(the model needs to 'write' to think\). Modern APIs provide separate reasoning tokens \(o1\) or extended thinking blocks \(Claude\) that are billed but not shown to the end user, achieving the separation without degrading the thought process.
