The way this is rolled out is super weird. Ultra bold - shocking - claims by a credible researcher but zero details amidst tons of documentation and even code that would hint at how these two universes (model based simulation and model free generative models) are being unified beyond a lot of references to differentiable simulation…

Super exciting!

What method is Genesis using for JIT compilation? What subset of Python syntax / operations will be supported?

The automatic differentiation seems to be intended for compatibility with Pytorch. Will Genesis be able to interface with JAX as well?

The project looks interesting, but the website is somewhat light on details. In any case, all the best to the developers! It's great to hear about various efforts in the space of differentiable simulators.

In the sizzle reel, the early waterdrop demos are beautiful but seem staged, the later robotics demos look more plausible and very impressive. But referring to all these "4D dynamical worlds" sounds overhyped / scammy - everyone else calls 3D space simulated through time a 3D world.

> Genesis's physics engine is developed in pure Python, while being 10-80x faster than existing GPU-accelerated stacks like Isaac Gym and MJX. ... Nvidia brought GPU acceleration to robotic simulation, speeding up simulation speed by more than one order of magnitude compared to CPU-based simulation. ... Genesis pushes up this speed by another order of magnitude.

I can believe that setting up some kind of compute pipeline in a high level language such as Python could be fast, but the marketing materials aren't explaining any of the "how", if it's real it must be GPU-accelerated, but they almost imply that it isn't. Looks neat, hope it works great!
