OpenSpline gives your voice AI a realtime avatar in 5 lines, integrates with LiveKit and OpenAI Realtime
Mikasa0xdev · reddit · 2026-10-15
Developer Mikasa0xdev released OpenSpline, an open-source project that adds a realtime avatar layer to voice AI: supply a portrait and your agent's audio, and it generates synchronized talking video on your own NVIDIA GPU, with a lite model running locally on a single card.
- Built on SoulX-FlashHead
- Ships integrations with LiveKit, OpenAI Realtime, Gemini Realtime, ElevenLabs and more
- The author's contributions cover the runtime, streaming, agent integrations, and embeddable players
- Code on GitHub, demo at openspline.dev, plus a walkthrough video
Still early-stage; the author is seeking feedback and use-case ideas.
