Report #56752

[counterintuitive] Instructing 'Output ONLY code, no explanations' yields better and faster code

Allow the model a designated space to reason \(e.g., comments in the code, or a separate planning block\) before outputting the final code, even if you strip the reasoning later.

Journey Context:
Developers suppress explanations to save output tokens and parsing time. However, LLMs require intermediate token generation to perform complex reasoning \(implicit Chain of Thought\). Forcing the model to jump straight from prompt to code suppresses its ability to 'think,' leading to architectural errors and hallucinations. The small cost of generating hidden reasoning tokens pays off massively in code correctness.
