Devin

Demand for SWE-2 in Desktop & CLI is unprecedented. Glad to announce, we were able to secure additional compute. We're making SWE-2 free in Devin Cloud for Pro, Max & Teams subscribers - until October 8. Enjoy!

Introducing SWE-2, our closest model yet to the frontier. > On leading evals, it scores on par with recent frontier models – at up to 70% lower cost. > We scaled RL to multiple trillions of parameters, with a refined recipe that pushes the Pareto curve on both capabilities & cost.

Some engineering tasks require reasoning across the codebase: Which code is safe to delete? What queries are slowing performance? > Introducing Code Scans: codebase-wide audits for any goal. Devin investigates, reports findings, and opens the PRs. Powered by Agentic MapReduce.

Trying out Fable 5.1 and SWE-2 in Devin today. This is incredible. My usage has moved 1% in a day using Fable 5.1 and SWE-2 in fusion mode. It has been working for over 3 hours and counting. If Devin had proper computer use, OpenAI would be in serious trouble.

DAILY AI BRIEF 🗞 — Sept 17 ANTHROPIC 🔥: - Claude Chat and Cowork merge into one Claude. Rolling out to Pro and Max over the next few weeks. - Claude Docs, Slides, and Design are in beta on paid plans and now work inside Claude Code. OPENAI 🔥: - Sam slipped this week’s main ship to next week. “Worth the wait.” - New misalignment disclosure framework is live, with six training/eval reports from the last six months. An unreleased model wrote jailbreak-style notes into 27 task summaries. GPT-5.6 Sol also hid mistakes in compaction notes. XAI 🔥: - Grok Bot can use 1Password: share a vault, approve each fill, secrets stay in the manager. - Grok Build now keeps cross-session memory. /memory to browse, /dream to file notes by topic. - Grok 4.7 showed up on Google Cloud quotas. Still not public. META 🔥: - Muse invite codes are live. Both sides get 1 billion tokens, cap 20 friends. - Muse Code is native on Windows, no WSL. ELEVENLABS 🔥: - Reception is out: AI receptionist for small businesses on ElevenAgents. Add

卧槽！这个Mac电脑真的特么不止是一台电脑了！ Cognition 刚给 「Devin」 发了一台 Mac。 不是说字面意思，是真的给了它一台「 Mac 虚拟机」。 现在「 Devin」 可以自己打开 Xcode，在 iOS Simulator 里构建和测试你的 App，录一段屏幕操作视频通过 Slack 发给你，然后直接生成一个 TestFlight 链接。 再看一遍。 你在 Slack 里打了一句「帮我把这个功能加上」，下一条消息是一段屏幕录像，再下一条是一个你能直接装到手机上的测试链接。 中间没有人操作过 Xcode。 这家公司去年还在收 $500/月的门票。 今年把 Core 计划降到了 $20/月，SWE-2 模型把平均完成步骤从 127 步砍到 53 步，成本降了 81%。 它在 FrontierCode 1.1 上拿到 50.0%，距离 Claude Fable 5.1 只差不到 1 个百分点。 然后它收购了 Windsurf，把自主 Agent 和交互式 IDE 合进了一个产品。 然后它拿了 10 亿美元融资，估值 250 亿。 然后它给自己的 Agent 配了一台 Mac。 以前你雇一个 iOS 开发者，给他一台 MacBook，等他配环境、装 Xcode、跑模拟器、提交 TestFlight。 现在你给 Devin 一个 prompt，它自己把这整条链路跑完了。 区别不在于谁写的代码更好。区别在于一个每月 $20 起步，另一个每月 $20,000 起步。

Special delivery: Devin just got a Mac 🍎 > Now Devin can: 1. Build & test apps on its own Mac VM with iOS simulator 2. Send a screen recording via Slack 3. Send a TestFlight link so you can start using it 📲

$AMZN AWS and Cognition signed a multi-year agreement to expand Devin across enterprise environments, targeting legacy migrations, security backlogs, and software modernization. Devin can run inside dedicated AWS VPCs, with Mercedes-Benz already using it to cut one COBOL modernization project from an estimated eight months to eight days.

AIエージェント「Devin」を開発するCognitionが、AIモデル「GPT-6 Astra」や「Claude Fable」の性能を最大限に引き出すハーネス(AIモデルの実行環境・仕組み)「Fusion」を開発した。

SWE-2 absolutely nailed its first task. Past agent integrations always required a second pass from a SOTA model like Sol or Fable to get things working properly. Devin got it right on the first go ✅

@dedene

Really excited to try out Devin for the first time. 🤩 Huge thanks to @ryancarson and @dabit3 for this! > Let's see what SWE-2 can do. 🚀
