What is the Mechanism of Perplexity?

With sophisticated language models such as GPT-4 Omni and Claude 3, Perplexity AI enables intelligent and real-time search and discovery. It is not like regular search engines, and it knows what it means when you add context to your queries and it tells you where it’s getting information from so you know what to trust it with.

• Understanding the query. Perplexity extracts the intent, context and salient points of the question, which is how it analyzes the question with NLP.
• Web search. It pulls up relevant data from articles, websites, journals, research papers, news sites and live feeds.
• Information processing. The AI distills information, weeds out unused or irrelevant data and comes up with a clear, succinct answer.
• Citing sources. The answers contain numbered footnotes linked to the sources which enable the user to easily check the information.
• Response delivery. Produces a well organised output which is easy for users to comprehend and includes hyperlinked possibilities for further follow up.

Many language models do not have access to the internet to access information in real time, but rather come from information in their training data. Perplexity is able to access and process live data feeds, enabling it to offer accurate and up-to-date information on current events. Dynamic data feeds give Perplexity live data on sports scores, elections, weather, and other real-time events.

Perplexity’s Election Information Hub, for instance, for the 2024 US election, curated information from The Associated Press and provided real-time results for the presidential, senate and house races using the Elections API by Democracy Works. Users can see national and state-level outcomes, confirm candidate seats, and receive AI-generated policy stance and ballot measure reports.

Limitations of Perplexity

Perplexity AI is a handy tool for quick, citation-supported research, but it has some drawbacks that show it cannot completely replace human-led search engines or research.

Reliance on the quality of the source material

Perplexity AI uses pre-trained knowledge and current web search to create answers. This means that it can provide general answers, but the answers may not be accurate due to the quality of its sources. Perplexity may inadvertently replicate inaccuracies when the references cited come with misinformation, biases, or outdated facts.

The models it uses, including GPT-4 Omni and Claude 3, are trained on a huge amount of text data but are not capable of autonomously checking facts. This could make it more prone to errors with its existing library of content as well as with live search results, which means users may need to check critical information against trusted sources.

Restrained conversation

The main purpose of Perplexity is to provide brief responses to the queries, not to have an on-going conversation with the user. It holds on to the context of previous responses, enabling further questions, but it is not designed for long conversations, like chatbot-type AIs like ChatGPT or Gemini.

Laws and copyright issues

Perplexity gathers content from a number of internet sources, including media content, which may not have explicit permissions. Media organizations have been concerned about their materials being used by Perplexity without paying them or giving them credit. Such legal actions could hinder the platform’s access to and use of some content, potentially impacting its functionality and credibility.

Limited multimodal functionality

While Perplexity supports uploading images and documents in its Pro versions, its capability of interpreting complex visual data is still developing. It might not have the same accuracy or in-depth analysis as dedicated AI tools for computer vision applications, including image recognition or complex visual data processing.
