What Is Windsurf?Windsurf 是什么？
Windsurf is an agentic AI-native code editor, originally built by Codeium and launched in late 2024. Its signature feature is Cascade, an AI system with real-time awareness of your coding session: it reads files across the codebase, proposes multi-file edits, runs terminal commands, and iterates until the task is done — less steering required than chat-style assistants.Windsurf 是 Codeium 出品的 AI 原生编程 IDE，2024 年底发布。它的招牌是 Cascade 智能体：实时感知你的编码会话，跨文件读代码、提多文件改动、跑终端命令、迭代直到任务完成——比对话式助手需要的人工干预少得多。
⚠️ Ownership change (important): a reported $3 billion OpenAI acquisition collapsed in July 2025; Google then paid a reported $2.4 billion to license Windsurf's technology and hired CEO Varun Mohan, co-founder Douglas Chen and ~40 staff into Google DeepMind. Cognition AI (maker of the Devin autonomous coding agent) acquired the remaining company on July 14, 2025, and rebranded the editor "Devin Desktop" in June 2026 — windsurf.com now redirects to devin.ai. The product is actively developed under Cognition.⚠️ 所有权变动（重要）：传闻 OpenAI 30 亿美元收购在 2025 年 7 月告吹；随后 Google 以约 24 亿美元授权其技术并将 CEO Varun Mohan、联合创始人 Douglas Chen 及约 40 名员工招入 Google DeepMind。Cognition AI（自主编程智能体 Devin 背后的公司）于 2025 年 7 月 14 日收购了剩余的 Windsurf 公司，并于 2026 年 6 月将编辑器更名为 "Devin Desktop"——windsurf.com 现已跳转至 devin.ai。产品在 Cognition 旗下持续开发。
Beyond Cascade, Windsurf offers Supercomplete context-aware autocomplete, Command mode for quick targeted tasks, Plan Mode for structured agent workflows, Arena Mode for blind model comparison, and its in-house SWE-1 models alongside frontier models. Free and paid plans exist — check devin.ai for current pricing, as plans were merged into Devin's subscription line after the rebrand.除 Cascade 外，Windsurf 还有 Supercomplete 上下文感知补全、Command 模式（快速定点任务）、Plan 模式（结构化智能体工作流）、Arena 模式（模型盲测对比），以及自研 SWE-1 模型与前沿模型的双线支持。有免费档和付费档——更名后套餐已并入 Devin 订阅体系，价格以官网为准。
Windsurf's real differentiator was never the editor — it was Cascade's agentic flow: delegate a multi-file migration, go get coffee, and come back to a working diff. Under Cognition it now sits in one subscription with Devin's autonomous cloud agents, which is the honest upsell path for teams that outgrow the editor. The ownership chaos of 2025 is over — but verify the current plan names and prices on devin.ai before committing, because the standalone Windsurf pricing page is gone.
Windsurf 真正的差异化从来不是编辑器本身，而是 Cascade 的智能体工作流：把多文件迁移任务丢给它，泡杯咖啡回来就有可用的 diff。现在它和 Devin 的云端自主智能体并入了同一订阅，这才是团队从编辑器升级上来的诚实路径。2025 年的所有权动荡已经结束——但独立的 Windsurf 定价页已消失，付费前务必到 devin.ai 确认当前套餐与价格。

Cascade Agentic FlowsCascade 智能体工作流 — Maintains session context across the whole coding task — reads files, runs terminal commands, and iterates until done.整次任务保持会话上下文：读文件、跑终端命令、迭代直到任务完成。
-
SupercompleteSupercomplete 智能补全 — Context-aware autocomplete that understands what you're doing, not just what you typed.理解你在做什么、而不只是你敲了什么的上下文感知补全。
-
Command ModeCommand 模式 — Quick targeted AI tasks without leaving the flow — explain code, generate tests, fix errors.不脱离编码流的快速定点 AI 任务：解释代码、生成测试、修报错。
-
Arena ModeArena 盲测模式 — Compare two AI models side by side on the same coding task and pick the winner blind.让两个 AI 模型在同一个任务上盲测对决，选出更强的一方。
-
Model-Agnostic + SWE-1模型无关 + 自研 SWE-1 — Use frontier models or Windsurf's in-house SWE-1 family, tuned for coding workflows.可换前沿模型，也可用自研的 SWE-1 系列（为编程工作流调优）。
