If I want to use GLM 5.2 for my usecase, how do I use it locally?

I am new to Reddit, some issue with Local LLama, looks like I cant post there so I posted here.

I know about Ollama & Unsloth, I reseached and even found something modelstdio. My question is for now I am prototyping so I am doing good lets say if I use it locally, but once I decide that I want users now and make it available to the public. How will the thing work? I will need to keep my laptop on or do I use glm from Z.ai - I noticed they have plans which I can use, 20$ per month seems cheap, what is the catch there? Also anywhere else I can try to use it, does someone offer like free creds or something?
