Definition

Tool use in AI means giving the model access to external tools like calculators, search engines, or code runners. Instead of just answering questions, the AI can look things up, run scripts, or take actions using other services.

Example

AI uses a calculator plugin to solve math problems it can’t do in its head.

How It’s Used in AI

Used in agents, advanced chatbots, research assistants, and productivity tools. It lets AI go beyond text prediction and actually interact with the web, files, databases, or APIs. This helps the AI complete real-world tasks with more accuracy and flexibility.

Brief History

Tool use became more popular in 2023 as LLMs gained plugin capabilities. OpenAI's ChatGPT plugins, tools in Claude, and LangChain agent integrations led the way in expanding what AI can do beyond text generation.

Key Tools or Models

Platforms like ChatGPT Plugins, LangChain Tools, OpenAI Function Calling, Zapier AI Actions, and Claude's Tool Use API all support tool use in AI.

Pro Tip

Always check what tools your AI has access to—better tools = better results. But poorly scoped tools can cause errors or misuse.
