did you not read the Github link you posted? It specifically says the Anthropic's Claude was used in the TV "debloat" process and calls out Claude and Gemini as the options for repeating it
sure, if you're using locally hosted open-source models it avoids all the horrors of Silicon Valley and I've been told it's a useful tool, but I have yet to see anybody explain quantifiably and repeatably where a coding LLM actually saves time or effort in novel ways with trustworthy results. the software engineers I know say they spend as much time editing and proofing the LLM output as was "saved" by using it, and initial scientific surveys on its professional use say the same thing
I am open to being proven wrong but I am justified in not trusting technology that is being pushed by capitalist monsters who openly state they want to use it to eliminate jobs, especially creative human ones
