# Key Concepts
|
|
|
|
## Agents
|
|
Agents use an LLM to determine which actions to take and in what order.
|
|
For more detailed information on agents, and different types of agents in LangChain, see [this documentation](agents.md).
|
|
|
|
## Tools
|
|
Tools are functions that agents can use to interact with the world.
|
|
These tools can be generic utilities (e.g. search), other chains, or even other agents.
|
|
For more detailed information on tools, and different types of tools in LangChain, see [this documentation](tools.md).
|
|
|
|
## ToolKits
|
|
Toolkits are groups of tools that are best used together.
|
|
They allow you to logically group and initialize a set of tools that share a particular resource (such as a database connection or json object).
|
|
They can be used to construct an agent for a specific use-case.
|
|
For more detailed information on toolkits and their use cases, see [this documentation](how_to_guides.rst#agent-toolkits) (the "Agent Toolkits" section). |
