The default settings for Qwen-3 models according to Qwen-Team. Default means that reasoning is automatically enabled, unless you end your user message with `/no_think`.
For example if you just want to smalltalk then do this:
```
Hello there, how are today?
/no_think
```
-> The AI will respond immediately and naturally.
Otherwise, for example, if you have a more complex question during the course of the conversation to which you would like a more precise answer, simply do not use the `/no_think` tag and the AI will first start reasoning before finally answering.
Note that I've set repetition penalty to 1.1 - feel free to change this parameter and experiment with it, but the other parameters should remain unchanged if you want to follow Qwen's recommendations.
