We developers like to pretend that LLM's are akin to humans and that they've been using things like NYTimes like humans as educational material. But they are not. It's much simpler, proprietary writing is now integrated into the source code of OpenAI, it would be as if I would copy parts of other propriety code and copy paste it into my own codebase. Claiming copy paste is a natural evolving process of millions of ye…
The source code of the LLM is likely a few hundred lines of text describing the shape of the neural networks involved in the model.
None of the NYTimes content will be in the source code. NYTimes doesn't publish Python source code, it publishes human language news.
LLMs are conceptually simple, mostly matrix multiplications and some non-linear operations connecting each layer, in some loops based on attention, etc. It's the staggering amount of training data and compute that makes them complex.
