Tool calling
The broader pattern of letting a model choose and invoke available tools.
Example
A model selects the approved weather tool and supplies the city in the required format.
Why it matters
It helps an assistant choose an appropriate capability rather than use the same method for every request.
You'll hear it
“It selected search when this question needed the account record.”
Can you control it?
Sometimes
Sometimes. Some products or workflows let you influence tool calling, while others keep it fixed or manage it automatically. Check the settings and documentation for the tool you are using.
Common questions
- Can a tool call fail even when the AI chose the right tool?
- Yes. Missing permission, unavailable services or unsuitable details can prevent the action.
- Does a successful call prove the whole task is complete?
- No. The returned result may still need checking or further work.
- Can a tool description affect the choice?
- Yes. Unclear or misleading descriptions can steer the system toward an unsuitable action.
