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。

SenderStack is an AI writing and email productivity platform available as a Chrome extension and a web workspace. It drafts and replies to email in your own voice, lets you chat with multiple AI models, translate and summarize documents, and build simple automations that remove repetitive busywork from your day.
Generate replies, draft new messages, and produce multiple phrasing options from a Gmail sidebar without breaking your workflow.
Talk to several well-known AI models in one interface and pick the one that fits each research, writing, or summarization task.
Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.
Create custom personas for professional, casual, sales, or support writing and train them on your own tone so output matches your voice.

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。

免费 / 开源提供同等级的开源权重基础模型与多语言效能,但需要自行架构主机或第三方推理设定。
免费 / 开源Enables running open-source models locally on consumer hardware, but lacks DeepSeek's cloud-scale hosted reasoning power.
