Live Avatar AI: How We Reached 20 FPS Real-Time Streaming with a 14B-Parameter Model
14 days ago 高效码农LiveAvatar under the hood: how a 14-billion-parameter diffusion model now runs live, lip-synced avatars at 20 FPS on five GPUs A plain-language walk-through of the paper, code and benchmarks—no hype, no hidden plugs. “We want an avatar that can talk forever, look like the reference photo, and run in real time.” —Authors’ opening line, arXiv:2512.04677 1. The problem in one sentence Big diffusion models give great faces, but they are slow (0.25 FPS) and drift out of look after a few hundred frames. LiveAvatar keeps the quality, removes the lag, and stops the drift—so you can stream an avatar for …
Inferix World Simulation: How The New Block-Diffusion Engine Enables Real-Time AI Video Worlds
24 days ago 高效码农Mind-Blowing: A Chinese Mega-Team Just Dropped Inferix — The Inference Engine That Turns “World Simulation” From Sci-Fi Into Reality You thought 2025 was already wild? Hold my coffee. On November 24, 2025, a joint force from Zhejiang University, HKUST, Alibaba DAMO Academy, and Alibaba TRE quietly released something that will be remembered as the real turning point of AI video: 「Inferix」. It’s not another video generation model. It’s the dedicated inference engine for the next era — the 「World Model era」. In plain English: 「Inferix lets normal GPUs run minute-long, physics-accurate, fully interactive, never-collapsing open-world videos — in real time.」 …
Real-Time AI Voice Assistant: Build in 15 Minutes Using VideoSDK
4 months ago 高效码农Build a Real-Time AI Voice Assistant in 15 Minutes VideoSDK AI Agents “ A beginner-friendly, open-source walkthrough based on VideoSDK AI Agents For junior-college graduates and curious makers worldwide 1. Why You Can Build a Voice Agent Today Until recently, creating an AI that listens, thinks, and speaks in real time required three separate teams: Speech specialists (speech-to-text, text-to-speech) AI researchers (large-language models) Real-time engineers (WebRTC, SIP telephony) VideoSDK wraps all three layers into a single Python package called videosdk-agents. With under 100 lines of code you can join a live meeting, phone call, or mobile app as an AI …
