Private AI Infrastructure Platform

Run Enterprise AI

On Your Infrastructure.

Under Your Control.

ZStack AIOS is a self-developed AI infrastructure operating system built around three integrated layers — compute power, model services, and operations — giving enterprises a complete private AI platform without stitching together multiple tools.

Why Private AI

Why enterprises need
Private AI infrastructure

Don't settle for public cloud APIs. Keep your AI infrastructure
where it belongs — under your control.

Data never leaves your building
Public cloud AI APIs require sending your proprietary data — customer records, financial models, internal documents — to third-party servers. Private AI keeps sensitive data under your governance, always.
Predictable cost at scale
Cloud GPU pricing compounds fast. At enterprise inference volumes, the economics of on-premise GPU infrastructure become significantly more favorable. You own the hardware. You control the cost.
Model customization without compromise
Fine-tuning proprietary models on public cloud platforms means your training data and model weights live on someone else's infrastructure. Private deployment means full ownership of every training run and every model artifact.
Compliance by design
Regulated industries — financial services, healthcare, government — cannot use public AI APIs without extensive legal review. Private AI eliminates the compliance question entirely.
Architecture

One platform. Three layers.

Every capability from GPU scheduling to AI application deployment — built in, not bolted on.

Fully Integrated Stack
All three layers ship as one product — no integration projects, no separate vendors.
Layer 01
Compute Power Layer
The foundation: make every GPU work harder
GPU Management Partitioning Heterogeneous Scheduling
  • Multi-engine support: Deploy AI workloads on bare metal, VMs, or containers within the same platform.
  • 1% GPU granularity: Precise allocation down to 1% increments — dramatically reduces waste.
  • GPU passthrough at 95% performance: Full physical performance for demanding training workloads.
  • vGPU partitioning: Share GPU resources across teams without per-seat licensing from GPU vendors.
  • Heterogeneous scheduling: Unified management across multi-brand, multi-architecture GPU pools.
  • Real-time monitoring + self-healing: Resource utilization visible at all times; failures auto-recover.
Layer 02
Model Layer (AI MaaS)
From raw compute to running models — without the complexity
Training Evaluation Inference RAG App Deployment
  • Full lifecycle MaaS: Model training → evaluation → inference → updates, all managed through one platform.
  • Intelligent task decomposition: AI tasks dynamically broken down, routed, and scheduled for optimal resource use.
  • Distributed parallel training: Scale training jobs across multiple nodes with adaptive load balancing.
  • Model compression & optimization: Efficient deployment with adaptive scheduling between training and inference.
  • Broad model support: Generative AI, NLP, computer vision, multimodal — hundreds of large models supported.
  • RAG knowledge base: Local retrieval-augmented generation with multiple orchestration strategies and plugin integration.
Layer 03
Operational Layer
Governance, visibility, and reliability for enterprise AI at scale
Scheduling Billing Multi-tenant HA Security
  • Cross-platform metering & billing: On-demand billing across multiple GPU clusters, compute centers, and tenants.
  • Visual unified portal: Comprehensive, intuitive view of all AI resources across the entire infrastructure.
  • Elastic fault tolerance: Rapid failure localization and self-healing; cross-platform DR with minimal RTO.
  • Multi-tenant isolation: Resource quota management per team, project, or business unit.
  • Sensitive data detection: End-to-end data security — file-level isolation and localized data management.
  • High availability for AI: Elastic fault-tolerant self-healing module maintains service continuity for production workloads.
Product Advantages

Built for enterprise AI.
Not retrofitted.

Every design decision optimized for production private AI — not adapted from general-purpose infrastructure.

Low Barrier to Entry
Minimum 2-node deployment. Full platform capabilities from day one. No need to build a full GPU cluster before experimenting.
One-Stop AI Experience
Data management → model training → inference → app deployment. One platform, one interface, no integration projects.
High Cost-Effectiveness
Dynamic GPU partitioning maximizes hardware utilization. The same GPU cluster serves more teams, more workloads, with less waste.
High Performance
95% GPU passthrough performance for training. High-performance storage network optimized for AI I/O patterns. Adaptive load balancing for inference.
Security & Data Sovereignty
Localized data management. File-level isolation. HA and DR built in. Your models, your data, your infrastructure — entirely under your control.
Use Cases

Any scale. Works with the GPUs you already have.

ZStack AIOS supports heterogeneous GPU environments, eliminating the need
to standardize on a single vendor before running enterprise AI.

Scenario 01
Model Training and Fine-Tuning
Build AI that understands your industry
Fine-tune foundation models on proprietary datasets across industries including media, healthcare, education, government, and telecommunications. ZStack AIOS provides everything from compute scheduling to industry-specific training dataset storage — a complete end-to-end training environment on your own infrastructure.
Fine-tuning Foundation Models Industry-specific
Scenario 02
Model Inference at Scale
Deploy AI into production without cloud dependency
Run inference workloads for production AI applications using on-premise GPU resources. Dynamic scheduling ensures inference SLAs are met even as demand fluctuates, while keeping all data on your own infrastructure.
Production Inference Dynamic Scheduling SLA Guaranteed
Scenario 03
AI Application Deployment
Go from model to application in your own environment
Enable local implementation of RAG knowledge base applications. Support multiple inference service orchestration strategies and plugin integrations. Quickly deploy AI applications — chatbots, document analysis, vision systems — without sending data to external APIs.
RAG Chatbots Document Analysis Vision Systems
Compatibility

Works with your existing infrastructure.

No rip-and-replace. ZStack AIOS overlays on the GPUs you already own
and the ZStack platforms you already run.

Heterogeneous GPU Support
Multi-brand, multi-architecture GPU pools unified under a single scheduling layer. Legacy and new hardware work together — no silos.
