an LLM is a curiosity without user data, anyone with a big silo of data can put out something years behind frontier and still instantly see huge usage. No one wants to go to AI, they want AI to come to them, unless OpenAI can stake a claim in a super novel way they're the Dropbox.
It's not like someone is going to use insider OpenAI knowledge to build an LLM so advanced you switch email, phone, or ERP providers
Let's say Google's LLM has slightly poorer reasoning, and you have to be really clear when you tell it to delete your old emails. What are you going to do, go to ChatGPT and have it very eloquently walk you through how to manually delete your emails?
But the idea that Google, the terrifying nation-state, who covetously gobbled up most of the bright minds of a generation, just couldn't fathom RLHF, means you think there is some inherent magic at OpenAI.
I use OpenAI's models a lot, obviously they're great, but whole-thread-as-context as a product is not a product, and Google has people plural who could execute that from first principles.
If Apple, Google, or MS are integrating LLMs, they can't get away with "you can talk to this website". The intersection of "has the cash to train a LLM" and "LLM is itself the entire offering" is very small
If you mean the other kind of ERP they will definitely do that; it's basically all /r/localllama is about.
