由 PyTorch Lightning 创建团队打造的 AI 云平台

Nebius is an AI-focused cloud platform that gives teams non-virtualized NVIDIA GPU clusters, managed MLOps tooling, and a serverless inference layer so they can move from experiment to production on one stack.

免费 / 开源Metaflow is Netflix's open-source Python framework for building, running, and operating real-world machine learning, AI, and data science workflows. It keeps your code in plain Python while handling dependency management, versioning, orchestration, and elastic cloud compute.

用于扩展 AI 工作负载的托管 Ray 平台

FluidStack builds and operates large-scale compute infrastructure for AI, including gigawatt-class data centers and GPU clusters used for training and inference. The company designs its own power, cooling and data center systems, onshores manufacturing and deploys solar generation to supply the power its clusters need. Rather than a self-serve cloud console, FluidStack works with AI labs and enterprises to provision large reserved clusters, with orchestration tooling for the ML frameworks and schedulers those teams already use.
