Describe the bug
deepseek-chat only searches question without retrieving answer, while deepseek-v4-pro / v4-flash cannot respond at all and throw Error: Failed to create AI stream.When the AI assistant is set to deepseek-chat, it can output something, but it only searches for the user's question and cannot effectively retrieve the corresponding answer. Additionally, the system outputs the error message: Error: Failed to create AI stream.
To Reproduce
Steps to reproduce the behavior:
Set the AI assistant to deepseek-chat mode.
Input a question that requires retrieving relevant information to answer.
Observe that the assistant only echoes or searches for the question itself.
See the error: Error: Failed to create AI stream appearing in the console or response.
Expected behavior
The AI assistant should be able to effectively retrieve the corresponding answer based on the question, instead of only searching for the question text. No Error: Failed to create AI stream should occur.
