[Feature Request] Improve Opus model execution quality and provide configuration options

Bug Description
Opus 5 is unusable. I literally regret using it. It might be "smart" but it feels really dumb. Execution is lacking and its unclear how to change it. I have way better results and understanding using a cheaper and less sophisticated model
