What harness do you use with it? Are you using v4.1flash via open router ?
PS: I do not know why but opencode pushes CPU usage to very high which has NOT happened with DeepSeek harness even once.
Do you know if they retain your prompts or use it for training?
Different story with $DAYJOB where ZDR matters, but the beauty of open models is that you can find a provider hosting them in your preferred terms.
