how does Perplexity AI work

So if you’re ready to go “all in” with one article, this guide is for you.

Let’s dive right in. 

What Is Perplexity AI? 

Perplexity AI is a search engine that uses artificial intelligence to give you smarter answers. It combines a regular search engine with a really smart language model called GPT- 3.5 and GPT-4. 

This language model understands and processes language like a brain.

So, imagine you have a burning question and you turn to a search engine for answers. Usually, you get a bunch of search results that may or may not directly address what you’re looking for. 

But what if there was a search engine that could give you more comprehensive and informative answers?

That’s where Perplexity AI comes in.

Perplexity AI uses a large language model to process and understand natural language questions. The model is trained on a vast dataset of text and code, allowing it to learn the connections between words and concepts. 

For that reason when a user asks a question, the language model is able to generate a response that is both comprehensive and informative.

You can also ask follow-up questions on any topic for a deeper exploration, and Perplexity will respond, keeping its earlier responses in context.

Now you have the idea of what Perplexity AI is and trying to understand the exact process on how Perplexity AI works. 

How Does Perplexity AI Work? 

Perplexity stands out from other systems by using a combination of indexing/ranking and LLM-based search methods to solve queries. 

Unlike traditional search engines that rely solely on indexing and ranking algorithms, Perplexity leverages its language model capabilities to provide accurate and reliable answers.

Let’s dive into a more detailed explanation of how Perplexity’s unique approach works:

1. Search Process

At first, when you ask a question turning on the copilot mode, Perplexity AI begins a search process. 

It begins by examining its search index, which consists of a collection of relevant web pages. Perplexity AI also uses pages that are almost similar to your question. 

Relevant web pages mean pages that appear on Google SERP results when you ask any query. 

This index encompasses a range of sources, including popular web pages and featured snippets relevant to your query.

2. Language Model Analysis

Once the search is performed, Perplexity effectively utilizes its sophisticated language model (LLM) chatbot capabilities. 

The GPT-3.5 or the latest Open AI’s GPT-4 LLM is a powerful language model that has been trained on a massive dataset of text and code. 

It carefully analyzes the text to identify and extract the specific information that is relevant to your question.

3. Striking a Balance

Perplexity’s design aims to strike a balance between the strengths of a canonical search engine and the efficiency of an LLM model. 

Traditional search engines often require users to navigate through multiple links to find answers, which can be time-consuming. 

In contrast, Perplexity streamlines the process by presenting the extracted information directly, saving you the effort of searching through links.

4. Trust and Citations

To address concerns regarding unreliable or false information, Perplexity places a strong emphasis on citations. 

It is trained in a manner that allows it to provide only statements supported by proper citations. 

This ensures that Perplexity will not make claims without credible sources to back them up. 

By adopting this approach, Perplexity ensures the reliability and trustworthiness of the answers it provides.

By combining indexing/ranking with LLM-based search and incorporating the significance of citations, Perplexity aims to provide you with accurate and well-supported answers.  

It leverages the advantages of both approaches, delivering efficient and reliable information that you can trust.

What Is Large Language Model (LLM)? 

A Large Language Model (LLM) is a powerful artificial intelligence (AI) model designed to comprehend and generate human-like language. It undergoes training on extensive amounts of textual data, such as books, articles, and websites, to grasp the statistical patterns and relationships within language.

LLMs utilize deep learning techniques, including neural networks, and possess the ability to perform various language-related tasks such as natural language understanding, text generation, translation, summarization, and question answering.

These models are characterized by their enormous size and capability to produce coherent and contextually appropriate responses. They can generate text that closely resembles human writing, although they lack genuine comprehension and consciousness.

LLMs have numerous applications, such as chatbots, virtual assistants, content generation, language translation, and aiding in research and writing. They can understand and respond to user queries, provide information, and assist in various language-based tasks.

How Does Perplexity AI Make Money? 

Perplexity AI secured $26 million in Series A funding in March 2023, but its business model is still uncertain. However, the company has a strong financial position and currently provides subscription based paid services, which could generate substantial revenue.

It is possible that Perplexity AI will partner with other companies to generate revenue.

For example, the company could sell statistics or anonymous search queries to businesses that want to understand how people are using the internet, or it could license its technology to other search engines.

It is also possible that Perplexity AI will sell advertising space. The company could target ads based on the search terms that users enter, or it could sell sponsorships to businesses that want to be associated with its brand.

Ultimately, Perplexity AI’s revenue depends on its ability to attract users and advertisers. If the company can prove its search engine’s superiority, it will be well-positioned to generate income.

Remember, these revenue sources are not mentioned on Perplexity AI’s website, and it is written based on internet sources.
