Something I find interesting is that in the last year or so, the talk around AI shifted from the model architecture to the trained model. People talk about Mistral 7B e.g., not transformer with rotary position embedding and gelu feed forward network (I don't know Mistral's architecture). Contrast this to a few years ago we'd talk about Resnet or Retina-net or whatever, not so much about the facebook pertain on Image-…
Annnd nowadays tools like transformers can automatically select the architecture based on the name of the weights, so when interacting with LLMs, you generally just name the weights.
Also MANY models are just using the llama or llama2 architecture.
