I don't get this. Isn't this the same as saying "I taught my 5 year old to calculate integrals, by typing them into Wolfram Alpha"...so the actual relevant cognitive task (integrals in my example, "seeing" in yours) is outsources to an external API.
Why do I need gpt-oss-120B at all in this scenario? Couldn't I just directly call e.g. gemini-3-pro api from the python script?
"easiest/low tech" would be some sort of unix file-locking and inode. Only works if you are on the same host machine though...AAAND sounds like it would be quite hacky.
Which is a good thing :) I am all in for asking questions. If someone can't answer them, it usually means they have not thought about it and are either ignorant or will learn something themselves :D
(like me for your question, as I never tried TabSub with internet disconnected. Was delighted to see it works nevertheless)
