Standard architecture

Runloop Devboxes default to arm64 architecture. You can specify either x86_64 or arm64 explictly to choose the architecture for launched devboxes.
curl -X POST 'https://api.runloop.ai/v1/devboxes' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $RUNLOOP_API_KEY" \
  -d '{ 
  "launch_parameters": {
    "architecture": "x86_64"
    }
  }'

Incorrect usage: Mixing architectures between blueprints and devboxes

Blueprints created on x86_64 will not work on arm64 devboxes and vice-versa. You can safely leave out the architecture parameter when creating a devbox from a arm64 blueprint and manually specify the architecture when launching from x86_64.
