The most powerful and sophisticated models will be controlled by the largest tech corporations (i.e. Google, Meta, Microsoft, Amazon, IBM, Nvidia, etc). They will slowly embed the AI into their products as enhancements/features, and also they will rent out their models to other businesses sort of like an 'AI model as a Service'. Initially I think the cost to access a proto-AGI API will be expensive because it will be quite capable, but costs will dramatically decrease as more companies offer the service. While all of this is happening, there will be hundreds of open-source versions that are less powerful but still very good.

My prediction is that one of these large tech companies will get to AGI first, but they will keep it contained within their company for some time. They won't release it to everyone straight away. In the meantime, other large companies will get to AGI just by following the bread crumbs, and then quickly we will have AGI (or at least proto-AGI) in the hands of several companies. Once that happens, there will be a race to monetize it and productize it. It will take the world by storm. Every business will be racing to adopt these AGI models to improve their efficiency/output or whatever. Then the open-source community will crack the code, and it will be available to pretty much everyone. Whether you'll be able to run it on your own machine is another issue, though.
