    Tried both OpenCode and ZCode after getting frustrated with 1) performance of non-top-models in CC and 2) bloat.

    ZCode is great. But as tied to GLM as CC is to Claude models (i.e. you can change models but it will cost you UX, performance, money. OpenCode works pretty well for all models, but for CC and Z.ai their proprietary harness is just a little better.

    On the fence now what i will continue using. Probs ZCode will eventually give me the same frustration that CC gave me. so OC may be best.
