????????在工作流中deepseek-r1的think標簽內部的內容，很容易讓工作流其他的llm產生幻覺，導致不能良好的生成目標效果。

????????我們通過代碼的方式讓deepseek-r1既有think思考鏈的效果，又不傳遞思考鏈。

????????工作流的邏輯為上圖

去除think中的代碼為

import re
def main(answer: str) -> dict:cleaned_text = re.sub(r'<think[^>]*>.*?</think>', '', answer, flags=re.DOTALL)# 移除清理后可能在開頭的多余換行符final_text = re.sub(r'^\n+', '', cleaned_text)return {"result": final_text,}

這樣子生成的效果就將think內容替換了

整個工作流的代碼為
