Launch a Vast.ai GPU Instance

Guide the user through launching a GPU instance on Vast.ai.

User Request

$ARGUMENTS

Instructions

Step 1: Determine the Offer

If the user provided an offer ID (number), use it directly.

If they described requirements, search first:

vastai search offers '<query>' -o 'dph_total'

Present top options and ask the user to pick one.

Step 2: Gather Configuration

Setting Flag Default
Docker image --image Ask user (suggest pytorch/pytorch)
Disk size --disk 64 GB
Access method --ssh / --jupyter / --jupyter-lab --ssh
Direct connect --direct No (not all machines support it)
Startup script --onstart-cmd None
Environment/ports --env None
Pricing --bid_price On-demand (no flag)
Label --label None
Template --template_hash None
Volume --create-volume / --link-volume None
Mount path --mount-path None
Entrypoint --entrypoint Container default
Container user --user root

Common images: pytorch/pytorch, nvidia/cuda:12.1.0-devel-ubuntu22.04, vllm/vllm-openai:latest, tensorflow/tensorflow:latest-gpu

Step 3: Launch

vastai create instance <OFFER_ID> \
  --image <IMAGE> \
  --disk <GB> \
  --ssh \
  [--env '<DOCKER_OPTS>'] \
  [--onstart-cmd '<SCRIPT>'] \
  [--label '<NAME>']

Alternatively, auto-select an offer:

vastai launch instance -g <GPU_NAME> -n <NUM_GPUS> -i <IMAGE> -d <DISK> --ssh

Step 4: Verify & Connect

After creation succeeds (note the new_contract instance ID):

# Wait for running status
vastai show instances

# Get SSH connection
vastai ssh-url <INSTANCE_ID>

Provide the user with the SSH command or Jupyter URL.

Step 5: Volume Setup (if needed)

# With new volume
vastai create instance <OFFER_ID> --image <IMG> --ssh --disk 64 \
  --create-volume <VOLUME_OFFER_ID> --volume-size 100 --mount-path /root/data

# With existing volume
vastai create instance <OFFER_ID> --image <IMG> --ssh --disk 64 \
  --link-volume <VOLUME_ID> --mount-path /root/data

Safety

  • Always confirm offer ID and $/hr cost before creating
  • Remind user to vastai destroy instance <ID> when done
  • Warn about interruptible instances losing work if preempted
  • For spot: use --bid_price — if bid is too low, instance won’t start
