Step-by-Step Setup Walkthrough

6 Steps to First Run
1

Account Registration & Login Workaround

Step 1 of 6

Sign up via email or Google to avoid third-party OAuth redirect glitches.

  • •Visit Vast.ai via GPUy's direct referral gateway.
  • •Sign up using standard email and password or Google OAuth. (If GitHub OAuth fails with auth errors, use direct email registration instead).
  • •No identity verification, KYC questionnaire, or phone number confirmation is required.
Pro Tip: If you experience infinite loading with GitHub login, switch to email + password registration for instant access.
2

Deposit Prepaid Funds (Card, PayPal, or Crypto)

Step 2 of 6

Load credit into your account balance before searching for machines.

  • •Click 'Billing' in the top-right console.
  • •Choose your payment provider: Stripe (Cards), PayPal, or CoinGate (Crypto/USDT).
  • •Minimum deposit is only $5.00. Billing runs continuously on an hourly rate converted to per-second deductions.
3

Configure Your SSH Key in Account Settings

Step 3 of 6

Upload your public key to automatically inject it into every rented host.

  • •Navigate to 'Account' → 'SSH Keys'.
  • •Paste your public SSH key (`~/.ssh/id_ed25519.pub`) and save.
  • •Vast.ai will inject this key into the authorized_keys of any instance you rent.
Generate and Copy ed25519 Public Key
bash
ssh-keygen -t ed25519 -f ~/.ssh/vast_key -N ""
cat ~/.ssh/vast_key.pub

Filtering the Marketplace: Host Reliability & Bandwidth

Step 4 of 6

Use advanced filters to select high-uptime, unthrottled machines.

  • •Go to 'Search'. Filter by GPU model (e.g. RTX 4090, RTX 3090, H100).
  • •CRITICAL: Set 'Reliability' filter to ≥ 98% and 'DL Perf' to verified high ratings.
  • •Check 'Inet Down' and 'Inet Up' speeds. Aim for ≥ 500 Mbps to prevent agonizingly slow model downloads.
  • •Select your Docker Image (e.g. `pytorch/pytorch`, `runpod/stable-diffusion`, or custom Dockerhub repo).
Critical Warning: Never rent hosts with reliability below 95% — they are frequently residential rigs that may reboot or lose internet without warning.
5

Launch & Connect via Direct SSH Proxy

Step 5 of 6

Connect to your provisioned machine via Vast's proxy port.

  • •Click 'Rent' on your chosen instance. It typically transitions to 'Running' in 30-90 seconds.
  • •Click the blue SSH button to copy the custom SSH command with its assigned host and external port.
Connect to Vast.ai Instance
bash
ssh -p 12345 [email protected] -L 8080:localhost:8080 -i ~/.ssh/vast_key
6

Destroy Instance to Completely Stop Billing

Step 6 of 6

Prevent storage leakage on community-hosted nodes.

  • •On Vast.ai, stopping a machine keeps the host holding your disk, billing you disk storage per hour.
  • •To stop all billing completely, back up your results to Google Drive or Hugging Face, then click the red 'Trash' icon to Destroy the instance.

Insider Cost-Saving & Anti-Waste Tactics

#1: Set up 'Interruptible' (bid) pricing to get GPUs for as little as $0.15/hr.
#2: Check the host location in the search table to select the server geographically closest to you for lowest SSH latency.
#3: Always destroy instances when done rather than leaving them paused.

Frequently Asked Questions (Vast.ai Onboarding)

Q:Why does GitHub login fail on Vast.ai?

GitHub OAuth on Vast.ai occasionally fails due to strict session cookie validations or adblockers blocking the callback script. Use Google OAuth or direct email/password signup instead for 100% reliability.

Q:Can I rent a GPU without a credit card on Vast.ai?

Yes! Vast.ai accepts PayPal and cryptocurrencies (USDT, USDC, BTC) via CoinGate. You do not need an international credit card to get started.

Q:How reliable are Vast.ai machines for training models?

Vast is a peer-to-peer marketplace. For production training, filter by Datacenter hosts with Reliability ≥ 99% and high disk speeds. Residential hosts are great for hobbyist ComfyUI or batch inference, but can be rebooted by hosts.
