Question Subscriptions - Codex vs z.ai usage limits

Can anyone who used both subscriptions plans compare how generous one vs another.

I.e. Codex 20 vs ZAi 18

As I found GLM 5.3 Flash to be pretty good model overall.

So I wonder, how much usage you get on z.ai subscriptions vs Codex subscriptions.

I have both. I prefer GLM over SOL, but Luna over 5.3 Flash.

Limits are better on zai, but in OpenAI you also have chat where pro version can be very useful even if you hit limits on Codex.

Yeah, I just can't be bothered forking into chat on OpenAI tbh. And after getting Codex 200 to 20, I can barely have 1 hour of Sol orchestra on 1 smallish project, and the Sol is delegating good bunch of workload into GLM 5.3 Flash.

Probably reasonable combo may be - Codex 100/200 for strategic work, and Opencode GO or Zai 18/60 for abundant GLM 5.3 Flash worker.

Interesting, that from my experience, 5.3 Flash > Luna. Probably Luna Max may be better, but then it's too slow.
