Perplexity AI is a conversational search engine that uses large language models (LLMs) to answer queries using sources from the web and cites links within the text response.[3][4] Its developer, Perplexity AI, Inc., is based in San Francisco, California.[5]
History
[edit]
Perplexity was founded in 2022 by Aravind Srinivas, Andy Konwinski, Denis Yarats and Johnny Ho, engineers with backgrounds in back-end systems, artificial intelligence (AI) and machine learning:
- Srinivas, the CEO (Chief executive officer), worked at OpenAI as an AI researcher.
- Konwinski was among the founding team at Databricks.
- Yarats, the CTO (Chief technology officer), was an AI research scientist at Meta.
- Ho, the Chief Strategy Officer, worked as an engineer at Quora, then as a quantitative trader on Wall Street.[6]
Services
[edit]Perplexity works on a freemium model. It also has an enterprise version of its product.[2]
Free plan
[edit]The free model uses the company's standalone LLM based on GPT-3.5 with browsing.[7][8]
It uses the context of the user queries to provide a personalized search result. Perplexity summarizes the search results and produces a text with inline citations.[8]
Perplexity also enables users to use Pages to generate customizable webpage and research presentations based on user prompts.[9]
Perplexity Pro
[edit]- Provides access to an API[8]
- Search both internal files and web content[10]
- Asks the user clarifying questions to refine queries
- Enables users to upload and analyze local files, including images
- Has access to GPT-4, Claude 3.5, Grok-2, Llama 3 and in-house Perplexity LLMs[11][4][2]
- Able to generate images using AI via Playground v3, DALL-E, Stable Diffusion and FLUX 1
Shopping hub
[edit]On 18 November 2024, Perplexity launched its shopping hub to attract users, backed by Amazon and leading AI chipmaker Nvidia. This will give users product cards which will show relevant items in response to asked questions about shopping.[12]
As a business
[edit]As of 2024, Perplexity has raised $165 million in funding, valuing the company at over $1 billion.[2]
As of November 2024, Perplexity is raising $500 million in a funding round that would elevate its valuation to $9 billion.[13][14]
In July 2024, Perplexity announced the launch of a new publishers' program to share ad revenue with partners.[15]
Perplexity AI plans to introduce ads [16][17] on its search platform by Q4 of 2024.[18]

Controversies
[edit]Forbes
[edit]In June 2024, Forbes publicly criticized Perplexity for use of their content.
According to Forbes, Perplexity published a story which was largely copied from a proprietary Forbes article, without mentioning or prominently citing Forbes.
In response, Srinivas said that the feature had some "rough edges" and accepted feedback, but maintained that Perplexity only "aggregates" rather than plagiarizes information.[20][21]
Wired
[edit]In June 2024, separate investigations by the magazine Wired and web developer Robb Knight found that Perplexity does not respect the robots.txt standard, which allows websites to stop web crawlers from scraping content, reportedly despite Perplexity claiming the opposite.
Perplexity also lists the IP address ranges and user agent strings of their web crawlers publicly, but according to Wired and Robb Knight, they use undisclosed IP addresses and spoofed user agent strings when ignoring robots.txt.[22][23]
Wired also stated that, in some cases, Perplexity may be summarizing:
"not actual news articles but reconstructions of what they say based on URLs and traces of them left in search engines like extracts and metadata, offering summaries purporting to be based on direct access to the relevant text."[22]
In response, Srinivas stated in a phone interview that:
"Perplexity is not ignoring the Robot Exclusions Protocol... We don't just rely on our own web crawlers, we rely on third-party web crawlers as well."
Srinivas explained that the web crawler identified by Wired was owned by a third-party provider.[24]
When asked whether Perplexity would cease scraping Wired content using third parties, Srinivas responded that "it's complicated."[24]
Amazon
[edit]Amazon Web Services, which hosts the Perplexity crawler, has a terms of service clause prohibiting its users from ignoring the robots.txt standard.
Amazon began a "routine" investigation into the company's usage of Amazon Elastic Compute Cloud.[25]
Lawsuits
[edit]In October 2024, The New York Times (NYT) sent a cease-and-desist notice to Perplexity to stop accessing and using NYT content, claiming that Perplexity is violating its copyright by scraping data from its website.[26]
NYT is also suing OpenAI and Microsoft for copyright infringement for similarly using millions of its articles to train the large language models that power ChatGPT.[27]
The cease-and-desist notice sent by NYT lawyers read in part:
"Perplexity and its business partners have been unjustly enriched by using, without authorization, The Times's expressive, carefully written and researched, and edited journalism without a license."[28]
Perplexity plans to respond to the notice by October 30, 2024.[26]
The same month, Dow Jones and New York Post filed a lawsuit against Perplexity, alleging copyright infringement. The lawsuit also alleges that Perplexity attributed quotes to an article on F-16 jets for Ukraine that never appeared in the original article.[29]
