[D] Are you excited about the upcoming Keras 3.0? (alien.top)

Creator of Keras confirmed that the new version comes out in a few days. Keras becomes multi-backend again with support for PyTorch, TensorFlow and JAX. Personally, I'm excited to be able to try JAX without having to deep dive into documentation and entire ecosystem. What about you?

My experience is that JAX is much lower level, and doesn’t come with batteries included so you have to pick your own optimization library or module abstraction. But I also find it makes way more sense than PyTorch (‘requires_gradient’?), and JAX’s autograd algorithm is substantially better thought out and more robust than PyTorch’s (my background was in compilers and autograd before moving into deep learning during postdocs, so I have dug into that side of things). Plus the support for TPUs makes life a bit easier compared to competing for instances on AWS.

It’s a drop in replacement for numpy. It does not get sexy than that. I use it for my research on PDE solvers and deep learning and to be able to just use numpy and with automatic differentiation on it is very useful. Previously I was looking to use auto diff frameworks like tapenade but that’s not required anymore.
