由 DeepSeek-V4 与 R1 驱动的高效开源权重与托管推理 AI,token 成本极低。
依托稀疏混合专家架构(V4-Pro 为 1.6T 中的 49B 激活参数),以极低延迟与内存开销处理最多 100 万 token。
由 DeepSeek-R1 开创并融入 V3.2 与 V4 思考模式,对复杂数学、逻辑与代码调试展示逐步自校验过程。
缓存命中时,输入 token 成本降至 Flash 的每百万 0.003 美元与 V4-Pro 的每百万 0.022 美元,非高峰 UTC 时段费率再低 50%。
在 chat.deepseek.com 及 iOS/Android 上免费提供文档上传、推理模式与网页搜索,核心模型不必付费墙。

Comet is Perplexity's AI-powered browser. It puts an assistant inside the browsing experience so you can ask questions about what is on screen, summarize pages, draft emails, build small artifacts, and delegate multi-step tasks across the web.
The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.

提供巨大的上下文窗口与深度的 Google 生态系整合,但对于纯推理任务感觉较不够专精。
