NVIDIA Open-Sourced a 2.6B World Model. It Runs on a Gaming GPU. (SANA-WM Breakdown)

Hinzugefügt: 2026-05-22

[00:00:00]6 months ago 1 minute of controllable 3D world cost $60,000 of GPU.

[00:00:08]Last night, NVIDIA open-sourced one that runs on a gaming card.

[00:00:14]Sana WM 2.6 billion parameters 60 seconds of 720p 1 RTX 5090 34 seconds to render.

[00:00:26]Apache 2 weekend project big distinction because everybody gets this wrong.

[00:00:33]A video model predicts pixels.

[00:00:36]Pretty footage.

[00:00:38]A world model predicts physics.

[00:00:41]Walk forward, the chair stays put.

[00:00:44]Turn left, the shadow moves right.

[00:00:47]Lift the camera new geometry appears that matches what you already saw.

[00:00:53]Until last week every serious world model Genie, Cosmos was closed weights and needed a data center.

[00:01:04]That wall just fell. Here is the flow.

[00:01:08]One image, your room, a forest, a robot arm one trajectory forward, pan, tilt 6 degrees of freedom.

[00:01:20]Sana WM generates the full 60-second video that obeys that exact path with consistent geometry every frame.

[00:01:31]The unlock is hybrid linear attention by gated Delta net plus softmax.

[00:01:39]So, memory doesn't blow up on long context.

[00:01:42]36 times the throughput of any open baseline. Real talk 90% of you watching haven't subscribed.

[00:01:52]On Facebook, subscribe is the supporter button.

[00:01:57]That is what keeps the lights on here.

[00:02:00]On YouTube, it is free and it tells the algorithm to send you more.

[00:02:05]Subscribe to support us. I packaged what world models actually unlock.

[00:02:11]Robot simulation data.

[00:02:13]Game environments from one image.

[00:02:16]AV scenarios, AR VR scenes.

[00:02:20]Sim to real. Seven use cases.

[00:02:23]Install config.

[00:02:25]Trajectory patterns.

[00:02:27]Six failure modes.

[00:02:30]One free PDF.

[00:02:32]Comment world and I will send it.

[00:02:36]One word.

[00:02:37]World.

[00:02:39]And the four guides below.
