GPU-Action: Zero-Downtime Spot GPU Failover Guard v2.0

PyPI Version License: MIT Security: Audited

GPU-Action is a lightweight, 100% local Python daemon that protects your AI inference & PyTorch training workloads on cheap Spot GPUs (Vast.ai, RunPod, AWS Spot) with zero downtime.

🔒 100% Local Security Guarantee

  • Zero-Key Leakage: Your VAST_API_KEY stays 100% local on your host machine.
  • Zero Admin Rights Needed: Runs entirely in unprivileged user space.
  • Auditable Open Source: 100% open-source Python code.

🚀 Quick Start

1. Installation

pip install gpu-action

2. Set Environment Variable & Run Guard

export VAST_API_KEY="your_vast_api_key_here"
gpu-action start --license-key YOUR_GPU_ACTION_LICENSE_KEY

⚡ How It Works

  1. 0.05s Eviction Detection: Monitors local/remote Vast instance health 24/7.
  2. Instant Failover: Automatically selects the cheapest, highest-reliability replacement Spot GPU upon eviction warning.
  3. 0% Downtime Proxy Rerouting: Seamlessly redirects active inference HTTP traffic to the replacement node.
