Heavy user proposes pairing OAI Pro with a 512GB Mac Studio running GLM-5.3 locally

- An OpenAI Pro subscriber says he burns through the $200 plan in a few hours and doubts the new $500 plan would last much longer, so he proposes a hybrid: keep OpenAI for the best models, plus a 512GB Mac Studio running GLM-5.3 locally for bulk usage.
- The math: Apple's published Klarna financing works out to roughly $400/month or less for the Mac Studio — fixed cost for effectively unlimited local inference.
- Caveat: the 512GB models are sold out, with delivery possibly later this year.
- He also found recent reporting on GLM-5.3's cyber capabilities interesting, and asks what he's missing.
