New software package enables interactive characters on mid-range graphics cards

The new software package includes plugins that connect speech recognition, small language models, and text-to-speech systems. Developers can use these components to create interactive characters that understand player input and respond with voice output.

NVIDIA designed the SDK to run on graphics cards with just 8GB of video memory. The 3060 meets this requirement, which allows mid-range hardware to handle AI companions without needing expensive upgrades.

The package contains a Qwen 3.5 4B model for decision logic and Chatterbox Turbo 350M for voice generation. NVIDIA also partnered with Epic Games to embed these tools into the MetaHuman NPC framework used in Unreal Engine projects.
