Openspline - host a realtime talking avatar on a commercial GPU (90+ FPS on RTX4090)

Explain Like I'm Normal

Openspline is a new open-source framework that allows developers to add real-time, lip-synced talking avatars to voice agents using local GPUs. By optimizing for speed, it achieves over 90 FPS on consumer hardware like the RTX 4090, solving the 'uncanny valley' lag common in digital humans. It requires only five lines of code to integrate with existing LLM-based voice workflows.
