How to call your model

Once you’ve deployed your model, it’s time to use it! Every model on Baseten is served behind an API endpoint. To call a model, you need:

• The model’s ID.
• An API key for your Baseten account.
• JSON-serializable model input.

You can call a model using:

• Its predict endpoint for the production deployment, development deployment or other published deployment.
• The Truss CLI command truss predict.
• The “call model” modal in the model dashboard on Baseten.

​

Call by API endpoint

• Production deployment

• Development deployment

• Development deployment

import urllib3
import os

model_id = ""
# Read secrets from environment variables
baseten_api_key = os.environ["BASETEN_API_KEY"]

resp = urllib3.request(
    "POST",
    f"https://model-{model_id}.api.baseten.co/production/predict",
    headers={"Authorization": f"Api-Key {baseten_api_key}"},
    json={}, # JSON-serializable model input
)

print(resp.json())

See the Baseten API reference for more details.
