Tencent quietly open-sources Hy-Nomas interactive video world model

Tencent Hunyuan published Hy-Nomas, an Apache-2.0 interactive world model, to Hugging Face on October 23, 2026, with training and inference code on GitHub and no blog post or paper. It generates video segment by segment with a persistent KV cache, accepting free-form text and camera-trajectory control mid-generation, at 720x1280 and 24 FPS in eight denoising steps, with an INT8 configuration that runs on a single RTX 4090.
