I'm getting a 403 when I start a training job

A 403 with a message like You are not authorized for Baseten training on truss train push usually means your workspace/account isn’t enabled for that training surface yet — it’s an access state, not a bug in your setup or config.

Before you write in, two quick checks:

• Confirm you’re logged into the workspace you expect with truss whoami, especially if you belong to more than one workspace.

• Confirm your API key belongs to that workspace and hasn’t been revoked.

If both check out, message us with your workspace name, what you’re training, and the model size, and we’ll help get you sorted. See How do I get access to Training?
