not sure I get this one. you’re gonna want to bbq roll the datacenter so the bulk doesn’t get roasted on one side, but will need to put the panels on bearings so they don’t rotate out of the normal plane

Everything you love about generative models — now powered by real physics!

Announcing the Genesis project — after a 24-month large-scale research collaboration involving over 20 research labs — a generative physics engine able to generate 4D dynamical worlds powered by a physics simulation platform designed for general-purpose robotics and physical AI applications.

Genesis's physics engine is developed in pure Python, while being 10-80x faster than existing GPU-accelerated stacks like Isaac Gym and MJX. It delivers a simulation speed ~430,000 faster than in real-time, and takes only 26 seconds to train a robotic locomotion policy transferrable to the real world on a single RTX4090 (see tutorial: https://t.co/bEkIlCKqdf).

The Genesis physics engine and simulation platform is fully open source at https://t.co/DhBv7NdyqH. We'll gradually roll out access to our generative framework in the near future.

Genesis implements a unified simulation framework all from scratch, integrating a wide spectrum of state-of-the-art physics solvers, allowing simulation of the whole physical world in a virtual realm with the highest realism.

We aim to build a universal data engine that leverages an upper-level generative framework to autonomously create physical worlds, together with various modes of data, including environments, camera motions, robotic task proposals, reward functions, robot policies, character motions, fully interactive 3D scenes, open-world articulated assets, and more, aiming towards fully automated data generation for robotics, physical AI and other applications.

@QiaochuYuan the brain minds and the mind thinks

@jam3scampbell updating more and more towards a diverse toolbox of archs with different capabilities rather than one model to rule them all

[alkali @thealkali]

@TeridaxDev consider problem domains far more complex than mc where we could never account for every possible interaction. imagine how a coherent, real-time state prediction engine trained on observation might model such processes. this demo is cool because it’s clearly not just about games

[alkali @thealkali]

@MarkovMagnifico i can’t help but marvel when i see this demo as i understand just how impossible it should be, and how quickly it’ll improve, and what this signifies (not just re: gaming)

the unfamiliar just don’t have the necessary context to be as awed, so revert to “it’s mc, but worse”

[alkali @thealkali]

@jam3scampbell Naan, jelly, achaar. Your life will be changed

[alkali @thealkali]

@GeorgeCrudo Gotcha— but I would posit that increased understanding of artistic intent is implied in “further improvement.” In any case, I wouldn’t expect the devs of a tool to release a demo reel that’s been touched up by other tools, for fear of misleading

[alkali @thealkali]

@GeorgeCrudo Genuine question(s) as I’m trying to burst the bubble/stay out of the echo chamber as much as possible lately: do you think the buck stops here? Like, do you anticipate no further improvement upon these techniques from now forward? I’m curious about accomplished artists’ opinions

[alkali @thealkali]

@aidan_mclau so frustrating. i’ve long been idealistic that excellent communication can bridge gaps of understanding. i loved dario’s essay— finally, a major figure publicly staking a similarly pragmatic position. shame the verge elects to talk past that position instead of to it directly

@francoisfleuret @DarioAmodei I do see what you’re saying, but if you’ll allow me some conjecture; Dario seems pretty reserved. As others have mentioned, he’s not very active on X— and, many of his media appearances are institutional rather than fireside. One can be private and still care immensely.

@pmarca right yes international security is surely commensurate with social media and this would not set a precedent on the muddling of public and private spheres at all
