# Key Concepts
|
|
|
|
## Python REPL
|
|
Sometimes, for complex calculations, rather than have an LLM generate the answer directly,
|
|
it can be better to have the LLM generate code to calculate the answer, and then run that code to get the answer.
|
|
In order to easily do that, we provide a simple Python REPL to execute commands in.
|
|
This interface will only return things that are printed -
|
|
therefore, if you want to use it to calculate an answer, make sure to have it print out the answer.
|
|
|
|
## Bash
|
|
It can often be useful to have an LLM generate bash commands, and then run them.
|
|
A common use case this is for letting it interact with your local file system.
|
|
We provide an easy component to execute bash commands.
|
|
|
|
## Requests Wrapper
|
|
The web contains a lot of information that LLMs do not have access to.
|
|
In order to easily let LLMs interact with that information,
|
|
we provide a wrapper around the Python Requests module that takes in a URL and fetches data from that URL.
|
|
|
|
## Google Search
|
|
This uses the official Google Search API to look up information on the web.
|
|
|
|
## SerpAPI
|
|
This uses SerpAPI, a third party search API engine, to interact with Google Search.
|
|
|
|
## Searx Search
|
|
This uses the Searx (SearxNG fork) meta search engine API to lookup information
|
|
on the web. It supports 139 search engines and is easy to self-host
|
|
which makes it a good choice for privacy-conscious users.
