Definition

LLM capability to call external functions when it decides they're needed to answer.

قدرة LLM على استدعاء وظائف خارجية عندما يقرر أنها ضرورية للإجابة.

Why It Matters

404Fault's AI Project Factory could use tool calling to let Claude search the glossary collection in Firestore mid-generation.

يمكن لمصنع مشاريع AI في 404Fault استخدام استدعاء الأدوات للسماح لـ Claude بالبحث في مجموعة القاموس في Firestore أثناء التوليد.

Full Definition

Tool use (also called function calling) lets you describe functions to an LLM (name, parameters, description) and the model decides when to call them. Instead of the LLM making up information, it calls get_weather(city='Dubai') and uses the actual result in its response. This connects LLMs to real-world data and actions.
استخدام الأدوات يتيح لك وصف الوظائف لـ LLM ويقرر النموذج متى يستدعيها. بدلاً من اختلاق معلومات، يستدعي النموذج get_weather ويستخدم النتيجة الفعلية.
