@dosubot[bot] commented on GitHub (Mar 25, 2025):

In Dify version 1.1.3, the issue of reasoning content being mixed with response content in LLM outputs is known. For version 0.15.3 and above, the separation of content and reasoning content is automatically handled using HTML details tags. However, there is currently no way to prevent the thinking information from appearing in API responses in version 0.15.3. This issue is expected to be addressed in the next version release, where the fix will move think tag rendering from the backend to the frontend to prevent HTML tags from being inserted into API response content [1][2].

For your specific case with the QwQ-32B model, you might need to implement a custom solution to filter out the reasoning content before passing the output to regex processing. This could involve parsing the output to remove or ignore sections marked as reasoning content.
