Truss allows you to securely manage API keys, access tokens, passwords, and other secrets without exposing them in code.

​
1. Define Secrets in config.yaml

Add secrets with placeholder values in config.yaml: 
secrets:
  hf_access_token: null
Never store actual secret values in config.yaml. Store secrets in the workspace settings.

​
2. Access Secrets in model.py

Secrets are passed as keyword arguments to the Model class: 
def __init__(self, **kwargs):
    self._secrets = kwargs["secrets"]
Use secrets inside load or predict: 
def load(self):
    self._model = pipeline(
        "fill-mask",
        model="baseten/docs-example-gated-model",
        use_auth_token=self._secrets["hf_access_token"]
    )

​
3. Store Secrets on Your Remote

  • On Baseten, add secrets in the workspace settings.
  • Use the exact name from config.yaml (case-sensitive).

​
4. Deploying with Secrets

By default, models have access to any secrets on a workspace.
