Qwen3.5 27B refuses to stop thinking

I've tried --chat-template-kwargs '{"enable_thinking": false}' and its successor --reasoning off in llama-server, and although it works for other models (I've tried successfully on several Qwen and Nemotron models), it doesn't work for the Qwen3.5 27B model. It just thinks anyway (without inserting a tag, but it finishes its thinking with ). Anybody else have this problem / know how to solve it? llama.cpp b8295 submitted by /u/liftheavyscheisse [link] [comments.
