They are moving beyond just big transformer blob LLM text prediction. Mixture of Experts is not preassembled for example, it's something like x empty experts with an empty router and the experts and routing emerges naturally with training, modeling the brain part architecture we see the brain more. There is stuff "Integrated Gated Calculator (IGC)" in Jan 2025 which makes a premade calculator neural network and integrates it directly into the neural network and gets around the entire issue of making LLMs do basic number computation and the clunkiness of generating "run tool tokens". The model naturally learns to use the IGC built into itself because it will always beat any kind of computation memorization in the reward function very quickly.
Models are truly input multimodal now. Feeding an image, feeding audio and feeding text all go into separate input nodes, but it all feeds into the same inner layer set and outputs text. This also mirrors how brains work more as multiple parts integrated in one whole.
Humans in some sense are not empty brains, there is a lot of stuff baked in our DNA and as the brain grows it develops a baked in development program. This is why we need fewer examples and generalize way better.
