AI / Claude Models Basics Interview Questions

What is the difference between an operator and a user in Claude's design?

Anthropic distinguishes between two types of principals who interact with Claude: operators and users. This distinction matters because it determines the level of trust Claude extends to instructions and how it resolves conflicting requests.

Operator vs User
AspectOperatorUser
Who they areCompanies or developers accessing Claude via the API to build productsEnd-users who interact with Claude through a product built by an operator
How they interactVia the system prompt and API configurationVia the human turn in conversation
Trust levelHigher — operators agree to usage policies and take responsibility for their platformLower — could be anyone; Claude applies more caution by default
Can they expand Claude's defaults?Yes — within limits Anthropic allowsOnly if the operator explicitly grants them operator-level trust
ExamplesA company building a customer service bot; a developer testing the APIThe end-customer chatting with the customer service bot

Trust hierarchy: Anthropic > Operators > Users. Operators can expand or restrict Claude's default behaviours for their platform (e.g. enable adult content on appropriate platforms or restrict Claude to only answer questions about their product). Operators cannot override Anthropic's core safety limits.

If there is no system prompt, Claude is likely being accessed directly by a developer and applies relatively liberal defaults.

How do operators interact with Claude compared to users?
What happens when there is no system prompt in a Claude API call?
