AI Applications
Perplexity
Perplexity is an answer-engine search product built on top of foundation models, with retrieval grounded in real-time web search and a citation-first answer format. The company raised $500M in late 2024 at a reported $9 billion valuation. The Pro tier integrates GPT-4, Claude 3.5, and Perplexity's own Sonar models with file upload and image generation.
Why this matters in 2026
Perplexity drew Forbes, Conde Nast, and New York Times complaints about content reproduction in 2024. The pattern is now the central legal question of AI retrieval products: how much of a source can a grounded model paraphrase before reproduction becomes infringement.
