# Vast.ai Hello World ## Overview Rent your first GPU instance on Vast.ai, run a PyTorch workload, and destroy the instance when done. Demonstrates the full lifecycle: search offers, create instance, connect via SSH, run a job, and tear down. ## Prerequisites - Completed `vastai-install-auth` setup - Vast.ai account with credits ($1+ recommended for testing) - SSH key uploaded to Vast.ai (cloud.vast.ai > Account > SSH Keys) ## Instructions ### Step 1: Search for Available GPUs (CLI) ```bash # Find cheap single-GPU offers sorted by price vastai search offers 'num_gpus=1 gpu_ram>=8 inet_down>100 reliability>0.95' \ --order 'dph_total' --limit 5 # Output columns: ID, GPU, VRAM, $/hr, DLPerf, Reliability, Location ``` ### Step 2: Search for Available GPUs (REST API) ```bash curl -s -H "Authorization: Bearer $VASTAI_API_KEY" \ "https://cloud.vast.ai/api/v0/bundles/?q=%7B%22num_gpus%22%3A%7B%22eq%22%3A1%7D%2C%22gpu_ram%22%3A%7B%22gte%22%3A8%7D%2C%22reliability2%22%3A%7B%22gte%22%3A0.95%7D%2C%22rentable%22%3A%7B%22eq%22%3Atrue%7D%7D&order=dph_total&limit=5" \ | jq '.offers[:3] | .[] | {id, gpu_name, num_gpus, gpu_ram, dph_total, reliability2}' ``` ### Step 3: Create an Instance (CLI) ```b

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill vastai-hello-world --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,630 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
