The ads angle is an interesting one since that's what motivates most things that Google and Meta do. Their LLMs' context window size has been growing, and while this might the natural general progression with LLMs, for those 2 ads businesses there's pretty straight paths to using their LLMs for even more targeted ads. For example, with the recent Llama "herd" releases, the LLMs have surprisingly large context window and one can imagine why Meta might want that: For stuffing in it as much of the personal content that they already have of their users. Then their LLMs can generate ads in the tone and style of the users and emotionally manipulate them to click on the link. Google's LLMs also have large context windows and such capability might be too tempting to ignore. Thinking this, there were moments that made me think that I was being to cynical, but I don't think they'll leave that kind of money on the table, an opportunity to reduce human ad writers headcount while improving click stats for higher profit.
