The SDK is a C/C++ agentic framework with Agent, Chat, and RAG APIs, optimized for small models on RTX hardware. The UE5 plugin suite covers ASR (nemo-conformer-ctc-120m), small language models (Qwen 3.5 4B via GGUF), and TTS (Chatterbox Turbo 350M), all with Blueprint and C++ support. Real-world use cases include KRAFTON's PUBG Ally AI teammate and a Total War: PHARAOH in-game advisor using RAG over 1,200+ game data tables. DLSS 4.5 plugin updates add Dynamic Multi Frame Generation and 6X Mode. NVIDIA also released Kimodo, an open source promptable human motion generation project with a UE5 plugin via Animotive. ## Full article daily.dev links to this article rather than hosting it.
