NVIDIA provides powerful vision language models through their NIM platform. The plugin enables real-time video understanding using models like Cosmos Reason2 with automatic frame buffering and NVCF asset management.
Vision Agents requires a Stream account for real-time transport. Most providers offer free tiers to get started.
