In this paper[1], the author used a KL penalty of 0.01 for general tasks and 0.001 for mathematical. I tend to think it&amp;#x27;s probably not very important unless you&amp;#x27;re trying to optimize for human preferences. As for response length, I think the model internalizes the logic and doesn&amp;#x27;t deliberate its answers through context creation. I don&amp;#x27;t think this is necessarily good for general reasoning, but for a specific task it would cut down inference costs. Just depends on what you&amp;#x27;re optimizing for. To encourage more general reasoning, I think a broader train and validation set…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/2501.03262/"&gt;Paper and discussion history&lt;/a&gt;.
