Nvidia CEO Jensen Huang told Lex Fridman in a Monday podcast interview that he believed AGI had been achieved, then seemed to slightly walk back the claim.
Training data isn’t stored in the model. The model processes that data and uses it to adjust the weights and measures of its parameters (usually several to a hundred billion or more for commercial models), which are divided among several layers, hidden sizes, and attention heads. These weights and the architecture are what are hard-coded into the model during training.
Inferencing is what happens when the model generates text from an input, and at this point the weights and measures are hard-coded so it doesn’t actually retain all that information it was trained on. The context window refers to how many tokens (words or phrases) it can store in its memory at a time.
For every token that it processes, it runs a series of calculations on embedded vectors passes them through several layers in which they’re considered against the context of all the other tokens in the context window. This involves matrix multiplication and is very compute-heavy. Think like 1-4GB of RAM for every billion parameters, plus several more GB of RAM for the context window. There’s just no way it would be able to hold its entire training dataset in RAM at a time.
You would need to integrate retrieval-augmented generation to fetch the relevant data into the context window before generating a response, but that’s not at all the same as containing all that knowledge in a stateful manner
