There was a time back in the years after dot com era where search servers were sold with the proprietary software loaded for enterprises to use. A google box running on your local network. Now there are advanced things like elastic and other search specific technologies that you can use.
I think LLMs might follow this market pattern where you can buy something to host yourself and then commoditization happens enough where open source solutions will also evolve to have good enough solutions.
An idea for a disrupting company would be to open source their LLM and offer support and feature development to enterprises as the paid offering, kinda like Red Hat or others doing that model. A key difference is running an LLM locally on decent sized compute is fine but it will be costly to scale on your own.
I feel like there's plenty of tech that has always been proprietary, and still is.
Yes, there's a lot of Open Source, and yes a lot of it is critical, but to see the current state as "open source " is not seeing the whole picture.
Google us not Open Source. Neither is Gmail, Google Maps etc. Then there's Windows, Office etc. What about AWS. Or iOS. Android is sorta open source, except for all the bits that actually make it useful.
And that's before we consider Facebook and friends. Or Netflix. Or Amazon shopping cart.
LLMs are following in the footsteps of pretty much every tech company, and every technology - it starts out life being proprietary. Maybe one day not just the software (llama) but the models will also be open source.
But no, it doesn't bother me at all. Most all Open Source is built on the ideas of proprietary software.
