Steps to reproduce

This bug was reported by someone two months ago, but it seems that it has not been addressed yet. https://github.com/langgenius/dify/issues/32679

Using the deepseek-v4-pro model, if deep thinking is triggered, the content of 【reasoning_content】 will be directly included in the return value 【text】. However, the 【reasoning_content】 in the return value will be empty.

The Qwen model will do the same.

This uncertainty requires the addition of a processing node after each LLM, which is quite troublesome.

✔️ Expected Behavior

The deep thinking content should be returned to 【reasoning_content】

❌ Actual Behavior
