Tencent’s HY-World 2.0 is officially dropping, bringing open-source multimodal 3D world generation that exports directly to game engines as editable meshes and 3D Gaussian Splatting, pushing well beyond standard video synthesis. Meanwhile, SenseNova’s NEO-unify is turning heads by ditching the VAE and vision encoder entirely for a 2B parameter native image generation architecture that processes raw pixels with an impressive 31.56 PSNR. On the cybersecurity front, OpenAI quietly rolled out GPT-5.4-Cyber to trusted testers to rival Anthropic’s Mythos, just as the UK AI Security Institute reported Mythos successfully completed 3 out of 10 simulated corporate network attacks without human intervention.
