Aravind Srinivas: 我创办Perplexity的初衷并非要打败Google,而是想探索一个具有同样规模和雄心的想法。我最初在OpenAI实习时,受到Ilya Sutskever的启发,开始研究无监督学习和生成模型。在Google实习期间,我阅读了《In the Plex》一书,这进一步激发了我创业的想法。我意识到,搜索和自动驾驶是少数几个能够同时进行AI研究和产品构建的领域。Perplexity最初的版本是一个基于Twitter数据的搜索工具,用户可以通过聊天界面进行查询。我们后来意识到,让模型在推理时处理大部分工作,而不是在索引时处理,是更有效的策略。我们通过一个简单的启发式方法,利用搜索API的顶部链接和摘要片段,构建了一个快速原型。我们发布的后续问题功能显著增加了用户参与时间,这让我意识到我们找到了正确的方向。我们最初担心微软的Bing Chat,但后来意识到他们并不擅长消费者产品。我更担心的是Google,因为他们的广告业务将阻碍他们在AI搜索领域的创新。我认为Perplexity比OpenAI和Anthropic更有优势,因为我们更关注用户体验和产品细节。我们能够利用最新的开源模型,并进行微调和评估。我们不仅关注模型和推理,也关注产品设计和用户体验。 David Lieb: 我对Perplexity在不到三年内估值超过90亿美元感到惊讶。我很想知道Aravind是如何将AI研究与产品构建结合起来的,以及他是如何克服挑战,最终创造出这样一款成功的产品的。
