Hey hunters If you've ever tried integrating a real-time AI avatar, you've probably hit one of these walls: 1. Video-generation APIs (HeyGen, Synthesia) — beautiful but not interactive 2. Cloud-rendered streams — 1-2 MB/s bandwidth, $0.10-$0.30/min, 3s+ latency 3. Open-source 3D avatars — you ship the GPU bill Spatius takes a different approach: cloud GPU only runs lightweight driving inference (~100 kbps stream of FLAME params), and the 3D Gaussian Splatting avatar renders on the user's device. Result: • $0.42/hour (vs ~$0.15/min industry average) • <1.5s latency (sub-second with end-to-end voice stacks) • 60fps on entry-level Android chipsets (G88, RK3576, etc.) • 99% of mobile/web devices supported, no dedicated GPU needed What's included: – SDKs for Web, iOS, Android, Flutter – LiveKit plugin + Pipecat-friendly – Python & Go server SDKs – Free commercial-use avatar – Generate your own avatar from a single photo (Beta) Free tier: 500 credits/month, no credit card. We'd love feedback on the docs, the demos, and especially what scenarios you're trying to build — language tutors, interviewers, companions, in-car assistants are where we're seeing the most traction.
