I'm happier with my Opencode Go running with the pi harness than Claude Code at work currently. I'm not sure if this will be that big of a moat, at least in the software dev market.
This and I very much miss reading the chain of thought. At least I have it on GLM-5.2.
I have zero quality issues on Z.ai Coding Plan and maki.sh as the coding agent, but I've seen many reports on 3rd party providers that they host heavily quantized versions of GLM models.
