Function Calling
Function calling is a pattern where a model outputs a structured request to invoke a tool or API, separating reasoning from action execution and enabling more reliable integrations.
Plain-English meaning
Function Calling is used here to describe structured tool invocation. In the daily board, the word is grouped by the role it performs rather than by spelling or market popularity.
You may encounter it in a product interface, technical document, risk report, policy paper, or market dashboard. The term is included for recognition and comparison, not as a product recommendation.
Why it belongs with AI Agents and Evaluation
Evaluation and controlled tool use help teams improve reliability without assuming the model is always correct or safe.
When solving the puzzle, compare the job this term performs with nearby cards. A correct group usually shares a function, risk type, workflow, or market structure rather than simply sharing similar wording.
Where you might see it
You might encounter this term while reading educational explainers, product documentation, risk disclosures, market dashboards, or beginner guides. Always separate vocabulary learning from financial decision-making.
