Validate activity before betting a new project on VirtualWife. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ## Common questions ### What is the difference between DeepSpeed and VirtualWife? DeepSpeed: Deep learning optimization library for efficient distributed training and inference. VirtualWife: VirtualWife是一个虚拟数字人项目，支持B站直播，支持openai、ollama. See the comparison table for live GitHub stats and shared categories. ### When should I choose DeepSpeed over VirtualWife?
