Function Calling是什么

Function Calling让AI模型不仅能生成文字，还能决定调用哪个函数、传什么参数。 比如用户说「帮我查一下北京的天气」，AI会调用get_weather(city=北京)，拿到结果后组织成自然语言回复。

支持的模型

Function Calling是AI从聊天工具变成生产力工具的关键一步。

Why This Matters

Understanding this topic is essential for anyone building AI applications in 2026. As AI agents become more integrated into production workflows, knowing how to properly implement these patterns can be the difference between a prototype and a reliable system.

Practical Tips

• Start simple and iterate. Dont try to implement everything at once.
• Test with real user scenarios before going to production.
• Monitor performance and collect feedback for continuous improvement.
• Keep learning - this field evolves rapidly.

Common Mistakes to Avoid

1. Over-engineering: solving problems you dont have yet
2. Under-testing: not validating edge cases
3. Ignoring costs: not monitoring token consumption
4. Skipping documentation: not documenting your prompts and configurations

Remember: the best AI agent is the one that actually works for your specific use case.
