Requesting Predictions

The AI services each have a route to the Seldon service. To create a prediction a POST request to the route under the path /api/v0.1/predictions. For instance, the flake analysis route on a CRC cluster in the Project `odh’ will look something like:


Models vary according to each service, but often, data is passed in through a field strData and parsed by the model accordingly. Within this strData field, most models require the a list of key value pairs separated by commas. For this reason, strData must have any other commas stripped out. Two common keys are model and data. A simple JSON body would look like:

{"strData":"model=healthpredictor/model.pkl, data=66:150"}

Putting that together in a curl command:

curl 'https://regrclassifier-odh.apps-crc.testing/api/v0.1/predictions' \
  -X POST \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d '{"strData":"model=healthpredictor/model.pkl, data=66:150"}'

Sample Output:

  "meta": {
    "puid": "k8h9uir10qdbsmv1qigp2qnk5l",
    "tags": {},
    "routing": {},
    "requestPath": {
      "c-regrclassifier": ""
    "metrics": []
  "data": {
    "names": [],
    "tensor": {
      "shape": [
      "values": [
