While the API was technically available, access has been limited or suspended due to national security and data privacy concerns raised by US authorities. Perplexity operates without such restrictions globally."},{"question":"Which is better for fact-checking and current events?","answer":"Perplexity is significantly better for current information and fact-checking because it performs live web searches and provides 15-20 cited sources per response. DeepSeek operates with a knowledge cutoff (April 2024) and cannot access real-time information, making it unsuitable for recent news or verification tasks."},{"question":"Which is more cost-effective for developers?","answer":"DeepSeek is 30-40% cheaper for API usage, with input pricing at $0.14 per million tokens versus Perplexity's $0.20. For high-volume applications, DeepSeek's R1 model can also be self-hosted open-source, eliminating ongoing API costs entirely."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/deepseek-vs-perplexity)","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/deepseek-vs-perplexity)), DeepSeek is a cost-optimized Chinese AI model excelling at reasoning and coding with lower operational costs, while Perplexity is a US-based AI search engine prioritizing real-time information retriev","dateModified":"2026-07-07T03:22:28.192Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/deepseek-vs-perplexity)","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/deepseek-vs-perplexity)","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/deepseek-vs-perplexity)","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/deepseek-vs-perplexity)#claimreview","url":"https://www.aversusb.net/compare/deepseek-vs-perplexity)","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"DeepSeek vs Perplexity","reviewBody":"DeepSeek is a cost-optimized Chinese AI model excelling at reasoning and coding with lower operational costs, while Perplexity is a US-based AI search engine prioritizing real-time information retrieval and citation accuracy with a freemium subscription model.","datePublished":"2026-07-07T03:22:28.152Z","dateModified":"2026-07-07T03:22:28.192Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/deepseek-vs-perplexity)","url":"https://www.aversusb.net/compare/deepseek-vs-perplexity)","name":"DeepSeek vs Perplexity","inLanguage":"en-US"}}}
