I think this is overselling their capabilities. I've used Gemma 4 and Qwen 3.6 quite a bit on my strix halo home server. They're great models and the dense variants are significantly better, but they're still very far behind the frontier. If you boot up Gemma 4 MoE and OpenCode/Pi and expect to perform anything like Claude Code or Codex you're going to be very disappointed.
Petsitter's default tricks doesn't seem to do much for Qwen3.6, right? JSON mode could be useful I suppose, but that's not really going to make it better at writing code. Do you have any other example tricks? I'm having a hard time understanding how I would apply them.
