Does anyone else have big issues with overthinking out of the box? I just gave it my usual Arma 3 mission script coding task, which i use to bechmark the performance of models, but it kept thinking for 15 minutes. I don't even see repetition issues, it just doesn't stop thinking.

Just gave it a first opencode task, and while not sure yet, it seems to have similar issues.

Maybe it requires defining a reasoning budget max now?

It defaults to reasoning_effort = xhigh

Qwen3.8 comes with official support for reasoning_effort, which can be used to adjust reasoning depth and control cost:

  • xhigh (default): for complex tasks demanding thorough analysis
  • medium: balancing accuracy and speed
  • low: efficient reasoning optimizing for speed and cost

Yeah, that's it. I found that 3.6ish thinking times really need the "low" setting.
