Nvidia has rolled out DLSS 4 alongside updates to its Broadcast app, timing the release with its new RTX 50 series graphics cards. The latest version of the AI upscaling technology uses a new transformer model to enhance image quality. Players can now update to the latest DLSS version in 75 supported games using DLSS 4 Overrides. The update lets users take advantage of the most recent improvements without waiting for individual game patches. The company has also updated Nvidia Broadcast, an app that taps into RTX graphics cards' AI capabilities to clean up audio and video in real time during video calls and livestreams. The app now includes a studio recording mode that mimics professional recording environments, plus video noise reduction and a virtual key light feature that uses AI to brighten faces and reduce shadows. Rounding out the updates, Nvidia has refined its RTX Video Super Resolution tool, which uses AI to improve the quality of online videos.
Nvidia is adding three new safety features to its NeMo Guardrails platform, aiming to give companies more control over their AI chatbots. The company says these microservices address common challenges in AI safety and content moderation. According to Nvidia, the Content Safety service checks AI responses for potentially harmful content before they reach users, while the Topic Control service tries to keep conversations within approved subject areas. A third service, Jailbreak Detection, works to spot and block attempts to bypass the AI's security features. Rather than using large language models, Nvidia says these services run on smaller, specialized models that should need less computing power. A few companies, including Amdocs, Cerence AI, and Lowe's, are currently testing the technology in their systems. The microservices are available to developers as part of Nvidia's open-source NeMo Guardrails package.
