Vast.ai CLI Helper

Teaches Claude to drive the `vastai` CLI for GPU instances, volumes, serverless endpoints, and billing on Vast.ai.

Dev & CodingIntermediate★ 220⑂ 94AI score 8/10Last updated: Sep 26, 2026

What it does

  • Provides a complete map of the vastai CLI: offer search, instance create/start/stop/destroy, SSH keys, file copy, volumes, templates, serverless endpoints, teams, API keys, and invoices.
  • Documents the query filter syntax (gpu_name=RTX_4090 reliability>0.95) and sort fields such as dlperf_usd and dph_total.
  • Gives a canonical workflow: register SSH key → search offers → create instance → poll status → copy data → destroy to stop billing.
  • Includes an actual_status table plus warnings about infinite poll loops, spot (--bid_price) pitfalls, and when GPU vs. storage charges start.

Who it's for

  • ML engineers and researchers renting GPUs on Vast.ai for training or inference.
  • Anyone automating instance lifecycle from scripts or an AI agent.
  • Users of prebuilt images like vLLM, ComfyUI, or the Linux desktop image.

Example uses

  1. "Find a verified single RTX 4090 offer with the best perf-per-dollar and launch it with the PyTorch image and 20GB disk."
  2. "List my running instances with hourly cost, then destroy everything labeled training."
  3. "Serve Qwen2.5-3B with the vLLM image using my HF token, then tail the last 100 log lines."
