09:27 我已经在主题演讲现场，活动将在半小时后开始。

今年，我用 vibe coding 做了一个系统，让自己能更方便地为现场博客添加照片。本来我打算使用 Codex Cloud 来做这件事（我是在去会场的路上用手机搭建的），但遇到了一些问题，于是改用了网页版 Claude Code。
与会者坐在明亮的工业风大厅中，面向大型舞台屏幕；屏幕上展示由彩色圆点组成的图案，场馆可见裸露的屋顶桁架和舞台灯光。

10:01 Sam Altman 登台欢迎大家来到 DevDay。他承诺这将是“我们有史以来最棒的一届 DevDay”。

10:02 他展示了他们已发布、且用户此前一直在要求的功能。Codex on Linux 和手机上的 Codex 都获得了一些掌声。

10:03 今天将推出一款让人感觉像是“与 AI 协作的全新方式”的产品。我猜它会是一个类似 Muse 的个人 Agent……

10:03
一名演讲者站在舞台上，面向观众；旁边的巨型屏幕显示“dots”字样以及四个彩色卡通角色。活动在一个拥有裸露屋顶桁架和舞台灯光的大型室内场馆举行。

10:03 它叫做“Dots”。

10:05 它看起来确实非常像 Muse。你可以为它选择名字，然后它会以一个可爱的团状头像呈现。（我的 Muse 头像是一只鹈鹕。）

10:06 这段演示视频中包含了大量语音交互，推测使用的是 GPT-Live 或这一技术的新一代版本。

10:06
一名演讲者站在舞台上，面向观众；旁边的大屏幕显示“dots”标志，以及与名为 Alfred 的助手进行模拟手机对话的画面。消息内容为：“good morning”、“Morning Sam! I’ve caught up on your Slack and email. Nothing urgent, just three things to look at when you get to the office,”以及“Let me know once you’re in and had your coffee.”

10:07 Dots“由 Astra 驱动”。这会是一个相当昂贵的默认模型！

10:08 这是一个非常有野心的使用场景：迁移一个 API。我很惊讶他们这么早就选择了如此重度编码的案例，不过我猜这里毕竟是开发者受众。
工业风场馆中的大屏幕展示了与 Alfred 的对话，以及公开 GitHub 仓库“superapp/engineering”的页面。Alfred 被要求在某库存 API 停止服务前将其移除，随后报告称已追踪其使用情况、检查依赖、更新集成并通过测试；GitHub 列出三个开放的 Pull Request：“Migrate the background jobs”、“Update checkout and subscriptions”以及“Replace the legacy API client”。

10:09 Sam 称 Astra 是“我们对齐程度最高的模型”，让你可以把“自己觉得舒服的那么多责任”交给自己的 Dot。

10:09 “你还需要一个让团队与各自 Dots 协作的地方。”因此他们推出了 ChatGPT Space。

10:10

这些 Space 看起来像是共享工件，可能是 Google Docs 与 artifacts 模式的结合。

Sam 介绍了 Holly Li。

10:11 Holly 正在讲解一个构建虚构音乐 App 的场景。Holly 有一个名为“Dottie”的 Dot，可以访问 ChatGPT、Slack、Teams 等更多服务。

10:12 这个 UI 的确很像 Meta 的 Muse Agent；后者目前仍位列 iOS App Store 免费榜第一。
一部智能手机的特写展示了与名为“dottie”的助手的对话。用户问“what time is my lunch party”后，助手列出工作更新：一次发布评审被提前、日历已更新、对 Blossom 反馈进行了 GTM 策略分析，以及一个新的主屏幕修订版；画面打开了包含“Copy”、“Select text”和“Reply”的菜单。

10:13 现场演示！“Dottie 今天早上有点慢”——我们看到了“still checking”，随后出现了一段尴尬的沉默。

10:14 现在进入 ChatGPT Space。它有一个 Notion 风格的斜杠菜单。
一台电脑屏幕展示文档编辑器，其中包含关于保存音乐和离线收听的 FAQ，以及用于添加可视化内容、页面、图片、文件和标题的菜单。下方正在起草“Customer Feedback”部分；状态气泡显示“Working for 33s”和“Thinking…”。

10:16 OpenAI 的员工开始直接在 Slack 中向自己的 Dots 委派任务；这些 Dots 在 OpenAI 的 Slack 中拥有各自的身份。我猜这是 OpenAI 对 Claude Tag 的回应。

10:17 “Dottie 可以在我的笔记本电脑上使用 Codex 来构建 App，并在 iPhone Simulator 中启动它。”

10:18 ChatGPT Pro 和 Enterprise 客户今天就可以获得 Dots 的访问权限。

10:19
Sam Altman 站在会议舞台上，面向就座的观众；旁边的大屏幕写着“People and AI, working together.”

10:19 他们还在构建面向法务、财务等领域的“专业 Dots”。他们将与企业合作推进这件事，也正在围绕这些能力与 Microsoft 365 开展合作。

10:20 “今天的第二个重要部分”是平台。Sam 表示：优秀的模型、工具——可访问 OpenAI 内部使用的同类工具——以及分发能力。

10:21 人们一直在要求推出比 GPT-6 Astra 更便宜、更快的版本。今天他们发布 GPT-6.1 Sol。

10:21 “以五分之一的价格，提供接近 Astra 水平的智能。”

10:22 6.1 Sol 将于今天发布。
一名演讲者在科技活动舞台上发言，面对坐着的观众和裸露的天花桁架。屏幕显示“GPT-6.1 Sol”，并与“GPT-6 Astra”对比价格：输入价格分别为 $2.00 与 $10.00，缓存输入价格分别为 $0.10 与 $1.00，输出价格分别为 $10.00 与 $50.00。

10:22 同样在今天发布：Ultrafast。速度提升 8 倍，最高可达每秒 300 tokens。可用于 API、ChatGPT 和 Codex。价格是标准模式的 6 倍——Sam 说，“你知道吗，这值得。”

10:22 Ultrafast 今日可用于 Astra 6，Sol 6.1 也将很快支持。

10:23 新订阅方案：Pro 500。它提供 Ultrafast 访问权限，以及 Plus 方案 25 倍的使用量。他们今天也重新向新订阅用户开放每月 200 美元的方案。

10:24 同样在今天：预览新的 Decisions API。它可以让模型“在几分之一秒内”作出响应。其工作方式是向 Luna 模型提供“一个预定义选项集供其选择”。这听起来像是对 Jev 的回应，后者在不到两周前才结束隐身模式、正式亮相！

10:26 Tejal 正在讲 Astra 的 Computer Use 能力。“我们的模型帮助优化了我们用于 Computer Use 的 harness。”他们加速了这个 harness，实现了“2 倍的延迟改进，并已向所有用户发布”。

10:27 “我们的模型在桌面和浏览器中导航时犯错的可能性大幅降低”——这“对你所有的 Dots 都应该非常重要”。

10:28
一名演讲者面向就座的观众，旁边大屏幕写着：“Agents are increasingly solving more complex problems for researchers.”图表比较了 2026 年 1 月和 7 月 Agent 在时长不断增加的任务中的成功率；侧栏显示，在零人工干预条件下完成 8 至 16 小时任务的成功率，从 1 月的 10% 提升至 7 月的 35%。

10:29 Sam 回来了。现在他谈到“支持开发者”——让开发者获得与 OpenAI 相同的基础能力。这从开源 Codex harness开始。Codex 现在也“全面上云”了。就在两小时前，我对云端 Codex 的体验很糟糕，所以希望这次的新发布能让它好很多。

10:30 今天发布“Codex Security Cloud”，提供“Daybreak Blue access”——包括定时扫描和自动去重。今天也已上线。

10:31 有一个（新的？）Agents API，现在支持 Computer Use。

10:31 （AWS 合作部分让我有点走神，不过只持续了几秒钟。）

10:32 Sam 正快速讲解企业隐私功能部分。

10:33 Sam 正在夸耀他们拥有当前“性能最高、最可靠的 API”。这感觉像是在针对 Claude，尤其是考虑到 Claude 就在今天早上发生了故障。

10:33 Romain Huet 刚刚以有趣的方式登场：他走进会场时进行了现场演示，屏幕上播放了摄像机画面。

10:34 看起来他将通过现场演示展示使用 Ultrafast 进行 3D 建模。语音模式没能配合！他只能改用打字。

10:35
科技活动的大屏幕展示了 Fort Mason Festival Pavilion 的计算机生成视图：场馆被布置为会议现场，成排座椅面向舞台，顶部可见裸露屋顶桁架。Codex 侧栏列出了包括“Fort Mason live demo”和“Map out the venue in 3D”在内的项目；画面底部可见观众的头部。

10:36 这是个不错的演示。他输入诸如“把直播放到大屏幕上”之类的命令，片刻之后，视频就出现在场馆 3D 模型中的大屏幕上。

10:38 Romain 正使用 Ultrafast 现场编写一个 App，向随机与会者发放免费门票。
OpenAI DevDay 会场的大型显示器展示了深色网页“DevDay Lucky 3”，提供三张 DevDay 2027 免费门票；页面包含三张票卡和一个“Spin”按钮。旁边的编程助手面板称，抽奖 App 已构建完成，并已通过构建验证。

10:39 （这符合一个模式：在此前的 DevDay 中，Romain 经常进行以有趣方式与观众互动的现场演示。）

10:39 现在是 Astra Computer Use 演示，Astra 要弄清楚如何玩一款新的、通过 vibe coding 制作的游戏。

10:40
工业风活动空间的大屏幕展示一款名为“ASTRA ADVENTURES”的太空飞行游戏，一艘飞船正接近小行星和一颗行星。界面显示速度为 018 m/s、推力为 20%，并提供“CRUISE”、“PATROL”、“CHASE”、“INVESTIGATE”和“BATTLE STATIONS”等控制选项；画面底部可见观众的头部。

10:41 ……接着是一个演示：Codex Remote 为 iPhone Duo 构建 App，并在 Codex UI 中展示来自模拟器的界面。

10:42 现在 Romain 切换到 Codex Cloud，输入“rewrite the entire backend in Rust”。

10:44
一名佩戴耳麦的男子站在木质讲台后，旁边有一个紫黄相间的小机器人，讲台上摆着笔记本电脑。背景是一面带有垂直绿色条纹的木质墙。

10:46 Sam 回来了。每周有 12 亿人使用 ChatGPT。“我们以前尝试过这个，结果有好有坏”，但他们准备再次尝试。首先是：sign in with ChatGPT，它让用户能够登录你的 App，并使用他们已经付费购买的 tokens。我已经想要这个功能很多年了！

10:46 还有：Plugin extensions——这些插件是“完整的应用程序”，在 ChatGPT（以及 Codex）中具有原生体验。

10:47 这里有一个来自 Adobe 的 ChatGPT 插件示例。
一名演讲者站在科技活动的舞台上，旁边的大屏幕标题为“Build your product.”屏幕展示一个软件界面，正在生成或编辑一张带着行李箱微笑女性的图像，前景中有观众观看。

10:48 你还可以构建 ChatGPT Sites，并将它们分享给指定的其他人。（我承认，我原本以为他们已经有这个功能了。）

10:49 他们还在今天推出 OpenAI Marketplace，并公布了这些合作伙伴。
舞台上的大型黑色屏幕写着“OpenAI Marketplace”，下方排列着 Adobe、Canva、Figma、Notion、Salesforce、Vercel 和 Zendesk 等公司的标志。前景中的观众正在观看，场馆顶部可见裸露屋顶桁架和舞台灯光。

10:49 最后以一段温情内容收尾，介绍了一些基于 OpenAI 平台进行开发的人。现场播放了一段视频。

10:52 他们会给每位与会者发一个这个东西，以及一次预先安排好的 reset。
一名演讲者站在舞台左侧、面对观众，旁边的大屏幕写着“Codex Game Studio”和“Today at 1PM”，并展示了一台掌上游戏机的图片。

10:53 他们在现场按下了按钮。这个 reset 会影响全球所有人，而不仅仅是 DevDay 与会者。
会议中的大型演示屏左侧展示了成排就座的观众，右侧展示一个蓝色 3D 图形：一个带云状符号的圆润物体放置在黑白条纹底座上。上方可见天花桁架和舞台灯光，前景中有与会者的头部。

12:47 我现在正在参加 ChatGPT Sites 主题会议。Jon Abrams 最初为这项工具制作原型，是因为他对内部工具如此难以上线感到沮丧（我在许多过去的雇主那里也感受过这种痛苦）。它在今年早些时候推出，如今已托管 800 万个站点，OpenAI 70% 的员工都在制作自己的站点。

12:47 Katia Gil Guzman 展示了一份记录 DevDay 发布内容的电子表格，并演示如何将其转换为一个 Site。“你能把这张表转成”

English / 原文

09:27 I'm in the room for the keynote, which starts in half an hour.

This year I vibe-coded a system for more easily adding photos to my live blog. I intended to do that using Codex Cloud (I built it on my phone on the way to the venue) but ran into problems with that and switched to Claude Code for web instead.
Attendees sit facing a large stage screen displaying a pattern made of colored dots in a bright industrial hall with exposed roof trusses and stage lights.

10:01 Sam Altman is on stage, welcoming us to DevDay. He promises "our best DevDay yet".

10:02 Showing features they've shipped that people asked for. Codex on Linux and Codex on your phone both got some applause.

10:03 Today, a product to feel like a "whole new way of working with AI". My guess is that it's a personal agent similar to Muse...

10:03
A presenter stands onstage before an audience beside a giant screen displaying “dots” above four colorful cartoon characters. The event is in a large indoor venue with exposed roof trusses and stage lights.

10:03 It's called "Dots".

10:05 It does look very Muse-like. You get to pick its name, then it's represented by a cute blob-like avatar. (My Muse avatar is a pelican.)

10:06 This demo video includes a whole lot of voice interactions, presumably using GPT-Live or a new generation of that technology.

10:06
A presenter stands before an audience onstage beside a large screen displaying the “dots” logo and a mock phone conversation with an assistant named Alfred. The messages read: “good morning,” “Morning Sam! I’ve caught up on your Slack and email. Nothing urgent, just three things to look at when you get to the office,” and “Let me know once you’re in and had your coffee.”

10:07 Dots are "powered by Astra". That would be an expensive default model!

10:08 A very ambitious use-case, migrating an API. I'm surprised that they went for such a code-heavy example so early on, I guess this is a developer audience.
A large display in an industrial venue shows a chat with Alfred alongside a GitHub page for the public “superapp/engineering” repository. Alfred is asked to remove an inventory API before it shuts down, then reports tracing its uses, checking dependencies, updating integrations and passing tests; GitHub lists three open pull requests: “Migrate the background jobs,” “Update checkout and subscriptions,” and “Replace the legacy API client.”

10:09 Sam called Astra "our most aligned model", to allow you to trust your Dot with "as much responsibility as you are comfortable with".

10:09 "You also need a place four your team to collaborate with their Dots". So they are introducing ChatGPT Space.

10:10

These Spaces look like shared artifacts, maybe Google Docs meets the artifacts pattern.

Sam Introduces Holly Li.

10:11 Holly is talking through a scenario building fictional music app. Holly has a Dot called "Dottie", which has access to ChatGPT, Slack, Teams, and more.

10:12 This UI really does look like Meta's Muse agent, currently still at number one on the iOS App Store free list.
A close-up of a smartphone shows a chat with an assistant named “dottie.” After the user asks, “what time is my lunch party,” the assistant lists work updates: a launch review moved earlier, calendar updated, analysis of Blossom feedback for GTM strategy, and a new homescreen revision; a menu with “Copy,” “Select text” and “Reply” is open.

10:13 Live demo! "Dottie is having a slow morning" - we got a "still checking" and an embarrassing silent moment.

10:14 Now we're in ChatGPT Space. It has a Notion-style slash menu.
A computer screen shows a document editor with an FAQ about saving music and offline listening, plus a menu for adding visualizations, pages, images, files and headings. Below, a “Customer Feedback” section is being drafted; a status bubble says “Working for 33s” and “Thinking…”.

10:16 People at OpenAI started delegating to their Dots directly in Slack, which have their own identities in OpenAI Slack. I guess this is OpenAI's answer to Claude Tag.

10:17 "Dottie can use Codex on my laptop to build the app and launch it in the iPhone Simulator."

10:18 ChatGPT Pro and Enterprise customers get access to Dots today.

10:19
Sam Altman stands on a conference stage before a seated audience, beside a large screen reading “People and AI, working together.”

10:19 They're also building "specialist dots" for legal, finance, etc. They'll collaborate with enterprises on this, and are also doing a thing with Microsoft 365 around these.

10:20 "The second big part of today" is about platforms. Says says: Great models. Tools - access to the same tools used within OpenAI. And distribution.

10:21 People have been asking for GPT-6 Astra but cheaper and faster. Today they're launching GPT-6.1 Sol.

10:21 "Near-Astra level intelligence at a fifth of the price".

10:22 6.1 Sol is launching by today.
A presenter speaks onstage at a technology event, facing an seated audience beneath exposed ceiling trusses. The screen reads “GPT-6.1 Sol” and compares prices with “GPT-6 Astra”: input $2.00 vs. $10.00, cached input $0.10 vs. $1.00, and output $10.00 vs. $50.00.

10:22 Also today: Ultrafast. 8x faster - up to 300 tokens/second. Available in the API, ChatGPT, and Codex. 6x the price of standard - "you know what, it's worth it" says Sam.

10:22 Ultrafast is available for Astra 6 today, and Sol 6.1 soon.

10:23 New subscription plan: Pro 500. This gives you access to Ultrafast, and 25x the usage of Plus. They're also putting their $200/month plan back on sale for new subscribers today.

10:24 Also today: previewing a new Decisions API. Lets the model respond "in a fraction of a second". It works by giving the Luna model "a predefined set of options to choose from". Sounds like their response to Jev, which came out of stealth less than two weeks ago!

10:26 Tejal is talking about Astra's abilities at Computer Use. "Our models helped optimize the harness we use for Computer Use". They accelerated the harness, getting "a 2x latency win that we've shipped to all of you".

10:27 "Our models are much less likely to make a mistake while navigating the desktop and the browser" - which "should really matter for all your Dots".

10:28
A presenter addresses a seated audience beside a large screen reading, “Agents are increasingly solving more complex problems for researchers.” A chart compares January and July 2026 agent success rates across tasks of increasing duration; a side panel reports success on 8–16-hour tasks with zero interventions rising from 10% in January to 35% in July.

10:29 Sam is back. Now talking about "supporting developers" - giving developers access to the same foundations they have at OpenAI. This starts with the open source Codex harness. Codex is also now "fully in the cloud". I had a bad experience with Codex in the cloud just two hours ago, so hopefully this new launch will make that a whole lot better.

10:30 Today launching "Codex Security Cloud", with "Daybreak Blue access" - scheduled scans, automatic de-duplication. Also launched today.

10:31 There's a (new?) Agents API, now with Computer Use.

10:31 (My eyes glazed over a bit at the AWS partnership section, but it only lasted a few seconds.)

10:32 Sam is dashing through a section about enterprise privacy features.

10:33 Sam is boasting about the "most performant and reliable API" available today. Feels like a jab at Claude, especially given they had an outage just this morning.

10:33 Romain Huet just made a fun entrance, with a live demo as he walked into the venue (with camera footage on screen.)

10:34 Looks like he's going to show off some 3D modeling with Ultrafast, in a live demo. The voice mode is not collaborating! He's going to have to type instead.

10:35
A large display at a tech event shows a computer-generated view of Fort Mason’s Festival Pavilion arranged for a conference, with rows of chairs facing a stage beneath exposed roof trusses. A Codex sidebar lists projects including “Fort Mason live demo” and “Map out the venue in 3D”; audience members’ heads are visible along the bottom.

10:36 This is a good demo. He's typing commands like "put the livestream on the big screen" and a moment later the video appears on the big screen in the 3D model of the venue.

10:38 Romain is live coding an app to distribute free tickets to random attendees, using Ultrafast.
A large monitor at an OpenAI DevDay display shows a dark “DevDay Lucky 3” webpage offering three free tickets to DevDay 2027, with three ticket cards and a “Spin” button. A coding assistant panel beside it says the giveaway app is built and the build passed verification.

10:39 (This fits a pattern - in previous DevDays Romain has frequently run live demos that interact with the audience in interesting ways.)

10:39 Now we have an Astra Computer Use demo, where Astra figures out how to play a new (vibe coded) game.

10:40
A large screen in an industrial event space shows a space-flight game called “ASTRA ADVENTURES,” with a spacecraft approaching asteroids and a planet. The interface shows velocity 018 m/s, thrust 20%, and controls including “CRUISE,” “PATROL,” “CHASE,” “INVESTIGATE” and “BATTLE STATIONS”; audience members’ heads are visible along the bottom.

10:41 ... and a demo showing Codex Remote building an app for the iPhone Duo, showing the UI from the simulator in the Codex UI.

10:42 Now Romain is switching to Codex Cloud, with "rewrite the entire backend in Rust".

10:44
A man wearing a headset microphone stands behind a wooden lectern beside a small purple-and-yellow robot, with laptops on the lectern. A wood-paneled wall with a vertical green stripe forms the backdrop.

10:46 Sam is back. 1.2B people use ChatGPT every week. "We've tried this before with variable results", but they're trying this again. First up: sign in with ChatGPT , which lets people sign into your app and use the tokens they are paying for already. I've wanted this one for years!

10:46 Also: Plugin extensions - plugins that are "entire applications" that feel native to ChatGPT (and Codex).

10:47 Here's an sample ChatGPT plugin from Adobe.
A presenter stands onstage at a technology event beside a large screen headed “Build your product.” The screen shows a software interface generating or editing an image of a smiling woman with a suitcase, while audience members watch from the foreground.

10:48 You can also build ChatGPT Sites and share them with specific other people. (I admit I thought they had that feature already.)

10:49 And they're launching the OpenAI Marketplace today, with these partners.
A large black stage display reads “OpenAI Marketplace,” with rows of logos including Adobe, Canva, Figma, Notion, Salesforce, Vercel and Zendesk. Audience members watch from the foreground beneath the venue’s exposed roof trusses and stage lights.

10:49 Finishing with a feel-good bit profiling some people who are building on OpenAI's platform. There's a video.

10:52 And they're giving every attendee one of these. And a banked reset too.
A presenter stands at the left of a stage before an audience, beside a large screen reading “Codex Game Studio” and “Today at 1PM,” with an image of a handheld game console.

10:53 They pressed the button live in the room. The reset affects everyone in the world, not just the DevDay attendees.
A large presentation screen at a conference shows an audience seated in rows on the left and a blue 3D graphic on the right: a rounded object with a cloud-like symbol sits on a black-and-white striped pedestal. Visible ceiling trusses and stage lights hang above, with attendees’ heads in the foreground.

12:47 I'm now in the ChatGPT Sites session. Jon Abrams initially prototyped this tool because he was frustrated at how hard it was to ship internal tools (I’ve felt that pain at many previous employers). It launched earlier this year and is already hosting 8m sites, and 70% of OpenAI employees are making their own sites.

12:47 Katia Gil Guzman demonstrates a spreadsheet of DevDay launches, and shows how to turn that into a Site. "Can you turn this sheet into a Launch Radar app in a new folder and publish it as a Site?"

12:48
Two presenters stand at wooden podiums on either side of a large stage screen, addressing an audience seated in a dark auditorium. The screen shows a software interface titled “Build and publish launch radar,” with a prompt about turning a Google Sheet into a launch radar app.

12:49 You can also tell Codex to keep an eye on e.g. a shared sheet and continually update the site with new details.

12:50 Sites get a SQLite database! They're launching scheduled tasks for Sites today.

12:51 They also have "Sign in with ChatGPT" support. Sites default to private.

12:52 Launching today is Plugins in Sites , which will allow a Site to display data that is personalized for the visiting user imported from their plugins. I recently noticed that Claude Artifacts can access MCPs, which looks like the same shape of feature.

12:53 Here's the Radar Launch app built as a live demo in the session.
A man stands at a lectern beside a large projected screen showing a launch-planning dashboard titled “Launch Radar [DEVDAY 2026].” The dashboard lists six launches, with three on track, two needing attention, and 13 of 30 milestones complete; a coding assistant interface is visible on the left.

12:54 You can add other people as "editors", which allows them to publish updates to the Site themselves.

13:01 Katia is now talking about WebMCP, and how much more efficient it is than using Computer Use.

13:32 Now a session by Kyle Brown on Ian Webster on Codex Security.

13:33 At OpenAI they had a security sprint a couple of months ago involving a quarter of their product engineers, and they fixed 53 critical findings on the first day.

13:34 Today they're launching a major upgrade to their Codex Security Cloud product, integrating lessons learned from their internal security sprint.

13:35
A presenter speaks to an audience at an OpenAI developer event, beside a large screen listing five steps: “01 Contextualize,” “02 Scan,” “03 Enrich,” “04 Patch” and “05 Integrate.” Another man stands behind a podium to the right.

13:37 They build a security knowledge base which includes architecture details and things that might not be visible in source code. They also now use SECURITY.md files, allowing product owners to define their own threat models and secure guidelines.

13:38 Running a scan using Codex Security.
A presentation screen styled as a terminal displays a prompt to review a document service for authorization boundary violations. It asks the reviewer to trace authenticated identity through document lookup and returned content; check ownership and organization membership; provide evidence, impact and remediation; distinguish confidence from severity; state validation limits; and not modify source during the scan. A curved line with colored dots appears beside the terminal, under the heading “01.”

13:39 The scanner keeps on looping until it can find no more issues.
A large presentation screen on a wood-paneled wall shows a terminal-style document titled “Document service architecture,” outlining identity, document fields, access rules and expected responses (401, 404, 403 and 200). A numbered “01” and a curved line with colored dots appear along the left side.

13:40 Deduplication is now available as a workflow in the CLI.
A presentation slide titled “03 Enrich the Findings” lists “Deduplication,” “Prioritization” and “Assignment.” Terminal windows show a codex-security dedupe scan and report deduplicationStatus: completed; the top of an attendee’s head is visible at the bottom edge.

13:41 In their internal sprint 36% of the discoveries were duplicates. Eliminating these saved a lot of developer time.

13:42 They put a lot of work into figuring out who owned what - a surprisingly hard problem in a company growing at OpenAI's rate.

13:43 Over time they got to the point where the system could generate patches. This was more of a "dial you turn up" as you get more comfortable with the quality of the results.

13:45 Now the codex-security patch command can generate patches and open PR. They only had a 1% rollback rate, thanks to a verify-fix command, which you can think of as an adversarial agent against the fix.

13:45
A presentation slide titled “Put scanning into the SDLC” shows a flowchart: “Validated finding” → “Codex generates a patch” → “Codex verifies the attack is blocked” and “Replays the original attack path” → “Draft PR” → “Human decides when to proceed / CI · Review · Merge.”

13:48 Here's a version of OpenAI's own internal burndown chart of their security vulnerabilities, showing the impact of their security sprint.
A presenter stands beside a large black display showing a red line that rises gradually, spikes sharply into several peaks, then plunges and settles near the bottom. Audience members watch from the foreground in a wood-paneled auditorium.

13:49 Codex Security Cloud lets you run continuous security. It's in the Codex plugins marketplace, and uses the Daybreak model that specializes in security.
A presentation screen shows a circular continuous-security workflow: Scan, Deduplicate, Validate, Prioritize, Patch, Verify and Review, arranged around the words “Continuous security.”

13:50 It runs a scan, lets you inspect the vulnerabilities, and can generate patches and open PRs. It should be generally available today.

14:13 I was wondering why OpenAI's visual identity for this event - the logos made up of animated clouds of dots, see first photo in this thread - felt somewhat familiar.

Then I realized they remind me of the Pluribus logo!

(I'm pretty sure that wasn't deliberate.)
The word “PURIBUS” appears in large white, striped letters against a black background scattered with small white dots.

Two presenters address a seated audience in a wood-paneled venue, standing on either side of a large screen showing a colorful line drawing of a carousel and a green-and-white sphere.
