I am working on a new project called Openspline, an open source avatar layer to existing voice AI agents.

Key points

  • Just select an image and you can create a realtime talking avatar with lipsynced video generated locally on your GPU.
  • You can integrate any existing voice AI agent in 5 lines of code.
  • The lite model can generate 90+ FPS on an NVIDIA RTX4090 gpu.
  • PS: sorry for a sleepy photo, it's 5:10am and didn't sleep last night :P
