New AI model turns photos into explorable 3D worlds, with caveats

arstechnica.com Unknown 2025-10-18 16:56:07

On Tuesday, Tencent released HunyuanWorld-Voyager, a new open-weights AI model that generates 3D-consistent video sequences from a single image, allowing users to pilot a camera path to "explore" virtual scenes. The model simultaneously generates RGB video and depth information to enable direct 3D reconstruction without the need for traditional modeling techniques. However, it won't be replacing video games anytime soon. The results aren't true 3D models, but they achieve a similar effect: The

Why the US government is taking a stake in Intel

techcrunch.com Rebecca Szkutak 2025-10-19 08:22:36

The Trump administration wants the United States to be the dominant force when it comes to artificial intelligence, and one way the administration hopes to achieve primacy is by bringing semiconductor manufacturing back to the U.S. To help with that transition, President Donald Trump has introduced potential chip tariffs and policies in recent months meant to bring more semiconductor manufacturing stateside.

Some time around the year 466 BCE – in the second year of the 78th Olympiad, the Roman naturalist Pliny the Elder tells us – a massive meteor blazed across the sky in broad daylight, crashing to the earth with an enormous explosion near the small Greek town of Aegospotami, or ‘Goat Rivers’, on the European side of the Hellespont in northeastern Greece.

We should have the ability to run any code we want on hardware we own

Sideloading has been a hot topic for the last decade. Most recently, Google has announced further restrictions on the practice in Android.

Can cheaper lasers handle short distances?

Optical technology is well established for long-haul communications, but the distances it serves are shrinking — especially in the data center. Vertical-cavity surface-emitting lasers (VCSELs) already drive short fiber links. But efforts are underway to further scale them down to provide more connections through waveguides than fiber can provide. “We have seen the transition from long haul to metro-to-local area networks and then into the data center,” said Suresh Jayaraman, senior director fo

Do the simplest thing that could possibly work

When designing software systems, do the simplest thing that could possibly work. It’s surprising how far you can take this piece of advice. I genuinely think you can do this all the time. You can follow this approach for fixing bugs, for maintaining existing systems, and for architecting new ones. A lot of engineers design by trying to think of the “ideal” system: something well-factored, near-infinitely scalable, elegantly distributed, and so on.
