It’s interesting how little attention this gets on HN. In my view it’s a huge achievement for a truly open source model, and a necessary check and balance on corporate control of AI.
Totally. I don't get why people sleep on AI2's launches. They're such powerful platforms for AI R&D.

I'm one of the many people who Soumith hired to Meta and PyTorch. I had the privilege of working on PyTorch with him and lots of the folks on this post.
As his longtime colleague, the one thing I would want people to know about him and this decision is that Soumith has always viewed PyTorch as a community project. He consistently celebrated the contributions of his co-creators Adam and Sam, and he extended the same view towards the Yangqing and the Caffe2 crew that we merged into PyTorch. At the very beginning, by Soumith's highly intentional design, PyTorch was aimed at being truly developed by and for the AI research community and for many years that was the key way in which we grew the framework, FB PT team, and the wider community. At every single stage of PT's lifecycle, he always ensured that our conception of PT and its community grew to include and celebrate the new people and organizations growing what was possible with PT. He's an incredible talent magnet, and thus more and more smart people kept dedicating their blood, sweat, and tears to making PT bigger and better for more people.
I've worked with some very well known and highly compensated leaders in tech, but *no one* has done the job he has done with ameliorating a bus factor problem with his baby. PT has a unique level of broad support that few other open source technology can reach. In a world of unbounded AI salaries, people who want to move AI research methods forward still freely give their time and attention to PyTorch and its ecosystem. It's the great lever of this era of AI that is moving the world, *due in large part* to the strength of the community he fostered and can now let continue without his direct involvement.
His departure is the end of an era, but it's also operationally a true non-event. PyTorch is going strong and can afford to let one of its creators retire from stewardship. This is precisely what success looks like in open source software.
He deserves our congratulations and our thanks. Enjoy your PT retirement, man.

Just curious, but is there any evidence that Chinese/Indian/etc will even be as open to US students as the US has been to them? I have no knowledge of what their intentions may be, but I think it’s a pretty large assumption that they would even take American students at all
American here who went to a Chinese (grad) school for CS and was admitted to every Chinese school I applied to. This is very much a possible route, if you’re appropriately qualified for the program. The main issue is language: outside of HK, programs in English are rare.

Not sure what's with the HN tone on this announcement. AI2 are really some of the best people around for creating truly open artifacts for the whole ecosystem. Their work on OLMo and Molmo is some of the most transparent and educational material you can find on model building. This is just great news for everyone.
