I signed up for a 3 month plan with Z.ai so I could try out GLM-5.1. That was a few weeks ago when it was still $27 for 3 months, now it's $48 for 3 months. I hit limits at least as much as I do with Claude. I hit a weekly limit at one point and it said I wasn't going be able to get access again for 6 days so I must've somehow hit their weekly limit on day one of the week. And that after several timeouts.
