# Spheron

> Spheron is an enterprise GPU rental marketplace. We aggregate NVIDIA and AMD GPU compute from Tier 2, 3, and 4 compliant data centers globally into a single platform with live pricing, 1-click deployment, and full root access. Developers and teams rent H100, B200, B300, A100, H200, GH200, L40S, RTX PRO 6000, RTX 5090, RTX 4090, and AMD MI300X GPUs for AI training, inference, and research at a fraction of hyperscaler costs.

Spheron is not a single cloud provider. It is a marketplace that aggregates GPU supply from multiple enterprise-grade data center partners. Prices fluctuate based on real-time availability. All infrastructure comes from Tier 2/3/4 compliant facilities (not consumer hardware). Customers get VM or bare metal options, per-minute billing, SSH root access, and zero vendor lock-in through a single account.

## Platform Details

### What Spheron Offers

Spheron is a GPU compute marketplace. You browse live pricing from multiple data center partners, pick a GPU configuration, and deploy in 60-90 seconds. Every instance comes with full SSH root access and a dedicated IP.

**GPU options:** NVIDIA H100, B200, B300, H200, GH200, A100, L40S, RTX PRO 6000, RTX 5090, RTX 4090, AMD MI300X.

**Instance types:** Virtual machines (quick provisioning, cost-efficient) or bare metal servers (zero hypervisor overhead, maximum performance). Multi-GPU configs up to 8x per node. Cluster deployments up to 80+ GPUs with InfiniBand (400 Gb/s) for distributed training.

**Billing:** Per-minute granularity after a 20-minute minimum runtime (60 minutes on a 2x AMD MI300X), no long-term contracts. Pay-as-you-go with credit card, bank transfer, or stables (USDT, USDC).

**Pre-configured templates:** PyTorch, TensorFlow, CUDA, JAX, Jupyter, NVIDIA Container Toolkit, and custom Docker images.

**Compliance:** All data centers are Tier 2/3/4 compliant. HIPAA, ISO 27001, SOC 2 Type I/II certifications available. 99.9% uptime SLA.

**Networking:** InfiniBand (400 Gb/s) and NVLink available on select providers for multi-node distributed training. Dedicated IPs for every instance.

### Who Uses Spheron

AI startups building LLM products. ML engineers and data scientists running training and inference. Enterprise teams deploying production AI platforms on compliant infrastructure. Research institutions and academic labs needing access to H100/B200 without capital investment. Generative AI developers working with Stable Diffusion, ComfyUI, and video generation. AI agent developers running distributed inference infrastructure.

### How Spheron Compares to Hyperscalers

Spheron aggregates supply from multiple data center partners, creating a competitive marketplace where prices reflect real supply and demand. This typically results in significantly lower per-hour GPU costs compared to AWS, Google Cloud, and Azure. Unlike hyperscalers, Spheron offers no vendor lock-in (switch providers through one platform), bare metal options alongside VMs, and per-minute billing without reserved instance requirements.

### Supported Frameworks & Tools

PyTorch (2.x with CUDA 12.1+), TensorFlow 2.x, JAX, Hugging Face Transformers, DeepSpeed, Megatron-LM, NVIDIA Triton Inference Server, vLLM, SGLang, RAPIDS (cuDF, cuML, cuGraph), ONNX Runtime, Docker, Kubernetes with NVIDIA Container Toolkit.
