面向 AI 与数据负载的无服务器云基础设施
直接写 Python，挂载 GPU 或容器，部署成随流量伸缩、空闲时缩容到零的 HTTPS 端点。
为编码智能体、强化学习 rollout 和不可信代码提供隔离安全环境，启动低于一秒，可支持百万级并发沙箱。
在弹性单机或多机 GPU 算力上运行微调、LoRA、全量训练和强化学习，无需等待配额审批。
通过兼容 OpenAI 的端点服务大语言模型以及图像、视频、音频模型，也可以自带推理栈，由 Modal 负责底层基础设施。
在你自己的云中运行的持久化 AI 运行时
任务、追踪与制品可跨基础设施故障存活。运行可派生、恢复并从最后一个成功步骤重放，重试与缓存由运行时统一处理。
具名、带类型并带版本的制品把团队连接起来，血缘图清晰展示某个版本由哪次运行产出、又被哪些下游任务消费。
控制面托管在 Union 云，负载在你自己的 AWS、GCP、Azure 或新云集群上执行，始终处于自有安全边界内。
支持接入 OpenAI、Claude、PydanticAI、CrewAI 等智能体，每一轮都被追踪并在临时容器中沙箱执行，支持 MCP 服务器与人工审批。
专项更强专为生成式多媒体模型优化的超快速无服务器运行环境，而非通用的 Python 代码。
Together AI is the AI Native Cloud — a full-stack platform for running, fine-tuning and training open-source models. It spans serverless inference APIs, dedicated endpoints, GPU clusters, post-training and storage, all backed by in-house systems research.

从全球市场按秒租用云 GPU
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.

通过 Cog 可以更轻松地打包模型，但不如 Modal 提供那么多样的无服务器 Python 容器运行方式。
由 PyTorch Lightning 创建团队打造的 AI 云平台
专项更强Combines ready-to-use model APIs and serverless GPU jobs, with simpler API consumption than custom Modal apps.
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.
