maybe determined should come up with its own API instead of copying Lightning's :)
Not a nice move for the opensource spirit. Also, pretty sure it's a violation of our patent and 100% copyright infringement.

In fact, our PyTorch API makes some significantly different design choices than Lightning does -- e.g., we require users to step optimizers and run the backward pass explicitly, which is a bit lower-level but allows for more flexibility when using the API.
For instance, here is an example of a GAN using our PyTorch API: https://github.com/determined-ai/determined/blob/master/exam...
This is a port of this PyTorch Lightning example: https://github.com/PyTorchLightning/pytorch-lightning/blob/m...
Despite the former being a port of the latter, there are significant differences between the two APIs.
More broadly, we welcome competition in this space and think there's a lot that we can all learn from one another.
If this is the philosophical stance that Grid and Lightning are taking then it's definitely a project I'm going to advice people to stay well clear off. It's the worst flavor of commercialized open source software and potentially a legal liability to touch in any way as you seem way too lawsuit trigger happy.
We want people to build on Lightning and we want companies to deliver value and products for their users.
We place no limitations on how Lightning is use or what products people will build.
Our in-process patent portfolio is not to limit the use of lightning in any way but for defensibility purposes only.
