Yep, main reason I ordered my Mac studio was because of privacy and control. I know no one will see the work being done on that machine and also the model will never be silently swapped out for a different lower quality model like anthropic does or a lower quant like openAI does with their models. Also having the inference engine has huge benefits because of speculative re-generation capabilities for voice agents. Anyways people who care about cost are simply bad at math if they think thell be saving any money running locally versus cloud providers.
