Vast.ai Local-to-GPU Canary Loop

Overview

Keep slow marketplace operations out of the inner loop. Validate code and the container locally, publish an immutable image, then use a single policy-constrained GPU rental only for the behavior that cannot be proven without CUDA.

Prerequisites

• Local unit and CPU-mode test commands with expected outputs
• Immutable image registry and a reproducible startup contract
• Canary GPU, price, reliability, timeout, and cleanup policy

Instructions

Step 1: Define the local contract

Use Read and Grep to identify entrypoints, required files, ports, and environment names. Write an explicit smoke command that works without cloud credentials.

Step 2: Run local gates
