“Like, for example, our five trillion run that we did, the outputs were 22 terabytes, and you want that kind of stuff in accelerator memory.”

Jenik: PDE feedback pushes physics AI models to exceed training data
“You can use those PDEs both for numerical simulators to generate data, but if you're clever about it, you can even use them as a training signal. You can check how well is my model actually doing on the PDEs themselves. And use that as an additional training s…”
Jenik: Accelerated Understanding has trained physics models up to 1-trillion parameters
“We've trained, done hundreds of training runs. We've trained up to a trillion parameter models. So we've really shown the stuff to take off.”
Jenik: Broadening PDE training domains solves the physical sim-to-real gap
“One interesting thing with PDEs is we are actually fairly confident, like the math is known, that when you solve a PDE correctly, you're doing the physics correctly. Like, obviously, you still need to make sure that you're representing the task that you're try…”
Jenik: Traditional chip design loses performance by separating digital logic and physics
“Especially when you look at the chip design itself, it was much more a, let's start in the digital, let's freeze the digital in, let's send it through some physics for a one time check, like the PDK dictates, I have to have The following feature, otherwise TSN…”
