Overview

The Perplexity AI Toolkit makes it easy to use Perplexity Labs' Sonar language models (built on top of LLama-3), LLama-3 and Mixtral, for creating chatbots, generating text, and searching the web (in real-time). It's designed for everyone, from beginners to experienced developers, allowing quick addition of AI features to projects with simple commands. While it offers simplicity and lightweight integration, it doesn't compromise on power; experienced developers can access the full suite of advanced options available via the API, ensuring robust customization and control. This toolkit is perfect for those looking to efficiently tap into advanced AI without getting bogged down in technical details, yet it still provides the depth needed for complex project requirements.

Key Features

• Search Functionality: Search online (in real-time) with the help of AI.
• Chat Functionality: Engage in interactive conversations with Perplexity's advanced conversational models.
• Command-Line Interface (CLI): Access the full suite of functionalities directly from the command line.
• Python Wrapper: Simplify interaction with a variety of models in only 2 lines of code.
• Streamed Responses: Receive responses as they are generated for real-time interaction.
• Flexible Configuration: Customize the token limits, system prompt, temperature, frequency penalty, and more.
• Minimal Dependencies: Built to be efficient and lightweight, requiring only the requests package for operation.

Prerequisites

• Python 3.x
• An API key from Perplexity AI

Dependencies

The following Python packages are required:

• requests: For making HTTP requests to the Perplexity API.

The following Python packages are optional:

• python-dotenv: For managing API keys and other environment variables.

Installation

To use the Perplexity AI Toolkit, clone the repository to your local machine and install the required Python packages.

Clone the repository:

git clone https://github.com/RMNCLDYO/perplexity-ai-toolkit.git

Navigate to the repositories folder:

cd perplexity-ai-toolkit

Install the required dependencies:

pip install -r requirements.txt

Configuration

1. Obtain an API key from Perplexity.

2. You have three options for managing your API key:

   Click here to view the API key configuration options

   • Setting it as an environment variable on your device (recommended for everyday use)

     • Navigate to your terminal.
     • Add your API key like so:

       export PERPLEXITY_API_KEY=your_api_key
       

     This method allows the API key to be loaded automatically when using the wrapper or CLI.

   • Using an .env file (recommended for development):

     • Install python-dotenv if you haven't already: pip install python-dotenv.
     • Create a .env file in the project's root directory.
     • Add your API key to the .env file like so:

       PERPLEXITY_API_KEY=your_api_key
       

     This method allows the API key to be loaded automatically when using the wrapper or CLI, assuming you have python-dotenv installed and set up correctly.

   • Direct Input:

     • If you prefer not to use a .env file, you can directly pass your API key as an argument to the CLI or the wrapper functions.

       CLI

       --api_key "your_api_key"
       

       Wrapper

       api_key="your_api_key"
       

     This method requires manually inputting your API key each time you initiate an API call, ensuring flexibility for different deployment environments.

Usage

The Perplexity AI Toolkit can be used in two different modes: Chat, and Search. Each mode is designed for specific types of interactions with the language models.

Chat Mode

Chat mode is intended for chatting with an AI model (similar to a chatbot) or building conversational applications.

Example Usage

CLI

python cli.py --chat

Wrapper

from perplexity import Chat

Chat().run()

An executable version of this example can be found here. (You must move this file to the root folder before running the program.)

Search Mode

Search mode is intended for searching online (in real-time) for a single query as perplexity does not support multi-turn conversations with their online models.

Example Usage

CLI

python cli.py --search --query "What is today's date?"

Wrapper

from perplexity import Search

Search().run(query="What is today's date?")

An executable version of this example can be found here. (You must move this file to the root folder before running the program.)

Advanced Configuration

CLI and Wrapper Options

To exit the program at any time, you can type exit or quit. This command works similarly whether you're interacting with the program via the CLI or through the Python wrapper ensuring that you can easily and safely conclude your work with the Perplexity AI Toolkit without having to resort to interrupt signals or forcibly closing the terminal or command prompt.

Available Models

Perplexity uniquely offers both native models and a selection of large, open-source models, providing a versatile and efficient way to leverage their API for a wide range of applications with both in-house and extensive community-developed models.

Perplexity Models

Open-Source Models

Where possible, Perplexity tries to match the Hugging Face implementation.

Online LLMs

Search mode is limited to 'online' models, such as sonar-small-online and sonar-medium-online. For these online LLMs, Perplexity recommends refraining from using system prompts.
