My combo is codex and claude basic subscription for planing the hard tasks (if any) opencode with GLM 5.1 (z.ai coding plan) for the actual coding.
replyopencode is awesome I don't miss cluade or codex cli at all, and the z.ai plan is way more generous in compression.
I was lucky to subscribe to z.ai coding plan pro when it costed 30$/month, I was surprised now it costs 70$/month.
In case anyone wants to subscribe to z.ai with 10% discount [1] * here is the credit campaign rules * [2]
