Yes — I have seen that more self-assured behaviour.
I have a test where I ask the model to ask me any followup questions it needs, and Qwen 3.8 27B is the only one I have seen that won’t routinely take this as a prompt to just ask questions regardless. Muse Glimmer sometimes decides it has what it needs and has no need to ask; Qwen will generally just conclude it doesn’t need any more information. And sometimes it will ask questions with sensible defaults that I can accept collectively with a single answer.
However, when given the prompt to search if they need to, both of them will search when they don’t need to.
