Great explanation here — thanks! Removing the <think> tag really cleans up DeepSeek output and makes articles much easier to work with. I just used the default regex (<think>.*<\/think>) in SCM’s DeepSeek settings and it worked perfectly by stripping the reasoning block so I only get the final answer. Super useful tip!
