Perplexity CEO Aravind Srinivas, Thursday Nights in AI

Key Learning from the AI Event with Aravind Srinivas:

  • Perplexity AI: Aravind Srinivas is the co-founder and CEO of Perplexity AI, a conversational answer engine that directly answers questions about any topic, launched shortly after ChatGPT. It uses large language models combined with search indexes to provide definitive answers with citations, unlike traditional search engines that yield links.

  • Usage and Approach: The platform has seen success, with metrics indicating users stay longer and interact more compared to others like ChatGPT or Bard. Perplexity AI's focus on being an answer engine rather than a search engine allows it to excel in providing research assistance.

  • Technology: Perplexity uses a combination of traditional search indexes and the reasoning capabilities of large language models (LLMs). It retrieves relevant paragraphs from various sources and cites them in concise answers, which helps minimize incorrect information (hallucinations).

  • Building on APIs: Initially built on OpenAI API, Perplexity AI has expanded to include specialized models and its search indexes. The aim is to become more self-reliant but still use OpenAI's models where beneficial.

  • Business Sustainability: By leveraging existing APIs and focusing on product-market fit first, rather than investing heavily upfront in infrastructure, Perplexity AI aims for a more sustainable and less risky growth path.

  • Product Differentiation: The emphasis is on providing a service that aids research and requires more than simple fact lookup. Perplexity differentiates itself from other AI products by sticking to its core principle of citation-backed answers.

  • Future Plans: The plan includes developing their own models alongside OpenAI's and enhancing capabilities such as conversational AI. Srinivas believes that in the next few years, it's possible to see refined AI assistants capable of conducting research autonomously.

  • Challenges of Rapid AI Development: Srinivas discusses the challenges of building AI startups at a time when larger companies are quickly advancing AI technology and the investment landscape is volatile.

  • Start-up Realities: Being pragmatic about fundraising, maintaining a product focus, and being motivated by proving detractors wrong are key factors in Perplexity AI's journey.

  • The Importance of Real User Feedback: Srinivas highlights the significance of using real-world testing over just benchmarking. OpenAI advocates for testing in production environments for truly robust and reliable systems.

  • Anticipating Technological Trends: On a longer time scale, predicting specific advancements is difficult. Srinivas emphasizes flexibility, staying user-focused, and not getting sidetracked by competitors' funding rounds or achievements.


The conversation provides insights into the strategic decisions and philosophy behind building an AI company in a fast-moving and competitive landscape. Srinivas emphasizes focusing on core strengths, gradual infrastructure build-up, and the importance of staying connected with the user's needs.
