@dosubot[bot] commented on GitHub (Feb 12, 2025):

I found two similar discussions that might be relevant to your issue:

  1. How to put the thinking process into thinking in DeepSeek R1 deployment in xinference, which is currently unsolved [1].
  2. Using DeepSeek's API, the thought process of DeepSeek cannot be displayed, which is also unsolved [2].

These discussions address similar concerns about the absence of the "Thinking" content in the output of the DeepSeek-r1 model. You might find additional insights or potential solutions by following these threads.

To continue talking to Dosu, mention @dosu.

You need to check the original context of the result to see if there is a think tag.

@lichao4Java commented on GitHub (Feb 12, 2025):

我发现了两个可能与您的问题相关的类似讨论：

  1. 如何把思考过程放到xinference中的DeepSeek R1部署中的思考中，目前尚未解决[1]。
  2. 使用DeepSeek的API，无法展示DeepSeek的思维过程，这也是一个未解决的问题[2]。

这些讨论解决了类似的担忧，即 DeepSeek-r1 模型输出中缺少“思考”内容。通过关注这些主题，您可能会发现更多见解或潜在解决方案。

要继续与Dosu交谈，请提及@dosu。

But the latest version of dify official and novita's supplier deepseek-r1 will output the Thinking tag?

你需要检查结果的原始上下文，看看是否有think标签。

novita's supplier deepseek-r1 will output the Thinking tag。 but Openrouter's deepseek-r1 no Thinking content 。

See related commits in https://github.com/langgenius/dify/releases/tag/0.15.3

Not all of the think tag content are supported at this moment, and we move it to frontend in feat: improve think content display (#13431).

I think we need to handle this later once the API is stable for both providers.

使用阿里云的千问接入deepseek的R1模型也是缺失思考过程

加1，我本地部署的deepseek填入localai和deepseek的模型供应商那里都缺失think过程，其他途径调用是有think过程的
