What Is Perplexity?Perplexity 是什么？

Perplexity is the leading AI answer engine: instead of ten blue links, it searches the live web and returns a direct answer with cited sources you can click to verify. One subscription includes a model picker across multiple vendors, Pro Search and Deep Research modes, file analysis, premium sources (Statista, PitchBook, S&P Capital IQ), the Comet agentic browser, and creation tools for reports, dashboards and presentations.Perplexity 是头牌 AI 答案引擎：不给你十条蓝色链接，而是实时联网搜索后直接给答案，每条答案都带可点击核验的引用来源。一个订阅包含多家大模型一键切换、Pro Search 与 Deep Research 模式、文件分析、高级数据源（Statista、PitchBook、标普 Capital IQ）、Comet 智能浏览器，以及报告/仪表盘/演示文稿创作工具。

Pricing in 2026: Free ($0, limited Pro Searches), Pro $20/month ($200/year), Max $200/month ($2,000/year, highest consumer limits with Computer credits and Create), Enterprise Pro $40/seat/month and Enterprise Max $325/seat/month. The developer API is billed separately from web subscriptions — the Decisions model pplx-decider-v1-27b costs $0.04 per 1M input tokens with free output tokens and no per-request fee; the Agent API charges web search at $0.0025 per invocation. Prices per the official site.2026 年档位：免费（$0，Pro 搜索次数有限）、Pro $20/月（年付 $200）、Max $200/月（年付 $2000，消费级最高上限，含 Computer 额度与 Create）、企业版 Pro $40/人/月、企业版 Max $325/人/月。开发者 API 与网页订阅分开计费——Decisions 模型 pplx-decider-v1-27b 定价$0.04 输入每百万 token、输出免费、无单次请求费；Agent API 的联网搜索按 $0.0025/次。价格以官网为准。

💡 Billing scope matters: Max benefits do not apply to programmatic API access — the API is always billed separately. And "unlimited" in one part of a plan is not proof of unlimited access everywhere: check model picker, research allowance, upload limits and credit pools as separate line items before you buy.计费口径提醒：Max 订阅权益不覆盖程序化 API 调用——API 永远单独计费。而且某部分写的「无限」不等于处处无限：下单前把模型选择、研究额度、上传上限、点数池当独立条目逐项核对。

Perplexity won the "answer engine" category by making citations the product: every answer is checkable, which is exactly what research workflows were missing from chatbots. At $20/month, Pro price-matches ChatGPT Plus and Claude Pro while differentiating on cited research and multi-model switching instead of raw model power. Max at $200/month is a power-user tier — justifiable only if Computer, Comet and Create are daily infrastructure for you, and it pointedly does not cover API usage. The sleeper value is the API: pplx-decider-v1-27b at $0.04 per 1M input with free output is a genuinely cheap decision/classification layer, and $0.0025-per-search Agent API pricing undercuts rivals' search tooling. Honest caveats: "unlimited" claims need line-item verification, and Chinese-web depth still trails Metaso (秘塔). Verdict: the best default AI search for cited research — start on Free, upgrade to Pro the week you hit the Pro Search limit, and evaluate the API separately from the subscription.

Perplexity 把「引用」做成产品，拿下了「答案引擎」这个品类：每条答案都可核验，这正是聊天机器人给不了研究工作流的东西。Pro $20/月与 ChatGPT Plus、Claude Pro 同价，差异化打的是带引用的研究和多模型切换，而不是裸模型能力。Max $200/月是重度用户档——只有当 Computer、Comet、Create 是你每天的工作基础设施才划算，而且它明确不覆盖 API。用 API 才是被低估的价值：pplx-decider-v1-27b 输入 $0.04 每百万 token、输出免费，是实打实便宜的决策/分类层；Agent API $0.0025 一次的搜索定价也比竞品的搜索工具便宜。真实短板：「无限」字样要逐项核验；中文网页深度仍不如秘塔。结论：带引用研究的默认 AI 搜索首选——免费先用，撞到 Pro 搜索上限那周再升级 Pro；API 和订阅分开评估。
