A lot of SOTA models seem to be gravitating towards transformer based models. Obviously, I can't speak for the entire field, but you can just go take a look at the most popular HuggingFace repos and see what I mean. They started out focused on language, but because transformers have become so popular, they're expanding into the audio and vision domains quickly. Their library called 'transformers' is, outside of research, most peoples go to high level framework as it largely abstracts away a lot of the boilerplate that writing in pure TF, PyTorch, Jax requires.
