Researchers have developed PhyAI, a unified inference engine designed to streamline the deployment of physical AI models across various platforms, including edge devices and cloud environments. This single runtime aims to maintain consistent checkpoint and action semantics while optimizing performance through model-specific adapters. PhyAI has demonstrated significant speedups over existing implementations for several vision-language-action and world-action models, though specialized runtimes may still offer superior performance in certain configurations. The engine's architecture allows for efficient execution on GPUs, with detailed profiling revealing performance bottlenecks related to latency and generation dominance for different models. AI
