I know there are many open source models, but they're designed to be 'build yourself and train them on your corpus' kind of solution...it's for professionals, not a ready working solution.
or even better...you can follow the money (aka bill gate's case back in the days_: contact big companies like intel, hp, lenovo etc to embed your AI into their hardware, so they market it as "for free offline AI assistant" while your contract with the company gives you millions, the vast majority of people have no idea what "45% on humanity last exam" means so even if your model isn't gemini 3.1 pro it will be considered a plus, and if it is then even better since it means people get something better without the hassle of paying online to sites they didn't know exist yesterday.
