Problem Description

How to enable thinking mode for DeepSeek 3.2 deployed via VLLM? After connecting to open-webui, normal conversations work, but I can't find how to enable thinking mode. Should I add parameters to the VLLM server startup settings, or add certain parameters in open-webui

Desired Solution you'd like
