Qwen thinking likes to second-guess itself a LOT when faced with simple/vague prompts like that. (I'll answer it this way. Generating output. Wait, I'll answer it that way. Generating output. Wait, I'll answer it this way... lather, rinse, repeat.) I suppose this is their version of "super smart fancy thinking mode". Try something more complex instead.

Indeed. Qwen doesn’t just second guess itself, it third and fourth guesses itself.

OK thanks! That's helpful. I ignorantly assumed simpler prompt == faster first response.
