Tencent's Hy4 Can See and Use a Computer

The 770-billion-parameter AI just got eyes and hands. Here's what it changes. LexxWire

Hy4 is a mixture-of-experts model: only a small slice of its 770B parameters fires up for each token. LexxWire

Hy4 reads photos, charts and visual math. In one demo it spotted a 2-metre rooftop detail in a 2.8-gigapixel aerial shot. LexxWire

Hy4 clicks through apps and runs command lines — trained on Blender, CAD and game engines like Unreal. LexxWire

The model is live through Tencent's cloud and APIs, but the downloadable weights are still promised, not published. LexxWire
