Lex Fridman: 本期节目讨论了Perplexity,一个旨在彻底改变人们获取互联网信息方式的公司。它结合了搜索引擎和大型语言模型(LLM),能够提供具有来源引用的答案,从而减少了LLM的幻觉,提高了可靠性。 Aravind Srinivas: Perplexity是一个答案引擎,它结合了传统搜索引擎和大型语言模型。搜索引擎负责提取与用户查询相关的结果,大型语言模型则负责根据这些结果生成具有来源引用的答案。Perplexity的成功在于这三者的协同工作。 Perplexity的答案生成方式类似于学术论文写作,每个句子都必须有来源引用,以确保准确性。Perplexity的诞生源于团队自身的需求,以及对提高聊天机器人准确性的探索。 Perplexity不仅仅是一个搜索引擎,更是一个知识发现引擎,它旨在帮助用户探索知识,而不是仅仅提供答案。通过提供相关问题建议,引导用户深入探索知识,实现知识的持续扩展和增长。 Aravind Srinivas: Perplexity不会与Google或Bing在搜索领域直接竞争,而是通过重新思考用户界面来实现颠覆。Perplexity通过将答案置于搜索结果的中心位置,而不是链接,来改变传统的搜索引擎用户界面。Perplexity押注于AI技术的指数级改进和成本降低,并致力于提供Google不愿提供的服务。 Google的主要盈利模式是搜索广告,而Perplexity的盈利模式将与之不同。Google的盈利模式多元化,即使搜索广告收入下降,公司也不会有风险。Google通过AdWords广告系统,利用其搜索引擎的巨大流量来获取广告收入。 Perplexity的盈利模式将不同于Google的链接广告模式,其答案是网站的第一方特性。Perplexity的长期商业模式目标是盈利和成为一家优秀的公司,但不必追求像Google一样的利润。 Perplexity的诞生源于团队自身的需求,以及对提高聊天机器人准确性的探索。Perplexity的初始版本是一个基于Twitter数据的问答机器人,后来发展成为一个通用的答案引擎。
