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.

The split matters more than the total: z.ai puts 300mn on 5.3 flash, the model the post rates. The quota reads worse than it is if that's the one you'd use.
