Contrail AIX™ is the world's first RISC-V AI Execution Platform, purpose-built for the next phase of artificial intelligence as the industry transitions from training models to deploying and executing intelligent applications at scale. Unlike traditional AI infrastructure, which separates CPUs for system management and GPUs for model processing, Contrail AIX is designed to support emerging workloads such as AI inference, reasoning, agentic AI, retrieval-augmented generation (RAG), autonomous systems, and physical AI, all of which require continuous orchestration, memory management, information retrieval, and workflow execution. Built on an open RISC-V architecture, the platform combines high-performance compute, AI acceleration, and a modern cloud-native software ecosystem, supporting technologies such as Ubuntu, Kubernetes, Docker, LLVM, GCC, MLIR, IREE, Ceph, and SPDK. By enabling intelligent agents to collaborate, access tools, retrieve knowledge, and execute complex tasks efficiently, Contrail AIX provides a unified and scalable foundation for the emerging AI Execution Era, where the ability to execute intelligence becomes as critical as the ability to train it.
