在OpenAI,Ultrafast如何将事件调查从几个小时减少到几分钟
这是我们系列的一部分，分享OpenAI如何使用自己的技术和API的内部实例。 这些工具正在OpenAI内部使用，并在此分享，以说明边境AI如何支持我们各团队的使用情况。
Ultrafast是Codex中的一种高速模式，对于OpenAI的工程师来说，工程师往往没有时间等待回答，利用Ultrafast，他们可以立刻调查多种潜在原因，并获得答案而不会分散注意力。
OpenAI的技术人员Aaron Friel通常是一个事件运行点。 他旋转Slack频道进行事件响应，然后将 Codex 指向问题，要求 Codex 监视，调查，并回答任何进来的问题。 他的称写道：“无论如何，我能够同时搜索所有的干草堆
AJ Trbojevic，技术工作人员和Datacenter安全建筑师，称对安全问题的调查，通常需要一两个小时才能将结构化和无结构化的数据拉到一起，使其正常化，并提供作出决定的背景。 称。 “现在这发生在10至15分钟内。” 「有时
亚当·佩里和萨扬·西索迪亚都为核心的agent团队工作，构建了让Codex采取行动，运行命令，以及使用工具的代码。 Ultrafast公司在安全事件中改变了运作方式。 「在此之前，我要求Codex调查一些事情，“现在随着Ultrafast,Codex已经足够快了，我只能集中精神，而不是分散注意力。”
Sayan欣赏Ultrafast如何让他立即从多个数据来源得到答案：“在一次事件中
称将检查Slack或与同事聊天。 但是他的大部分作品现在都与超快铁处于这一门槛之下。 他曾经问过Codex一个问题，在它思考时切换到别的东西，并在失去他的思维火车后回来。 现在，这种对话是实时发生的；这帮助他专注于手头的任务。
Ultrafast也使得杰夫更愿意处理大的重构物，因为对现有代码的重新工作需要的时间更少。 称先生说，“现在偿还技术债务比以前容易得多。 “守则很便宜，一个曾经花费很多钱的重构几乎立即发生。”
亚当保留了一条运行的Codex线，他称他的幕僚长。 每天早上，它都告诉他有什么会议，以及他可能忘记回答哪些信息。 他的称表示，“它已经研究了所有的数据来写这个摘要，所以当我要求后续调查时，“我只能像实际参谋长一样，在同一次谈话中继续提问。”
Sayan使用Codex在浏览器中做乏味的手工工作，“它会打开浏览器，坐在那里思考五秒钟，点击一些东西，再坐在那里，” 随着最新模型在计算机使用方面的改进，他更愿意让Codex处理这项工作。 “现在我完全可以点击浏览器
Ultrafast让OpenAI的技术人员按照问题的速度与Codex合作。 他们可以追踪一个答案，尝试另一种方法，继续工作而不失去他们的思维。 这段短暂的等待也改变了他们愿意承担的事情

How Ultrafast cut incident investigation from hours to minutes at OpenAI
This is part of our series sharing internal examples of how OpenAI is using its own technology and APIs. These tools are being used internally, at OpenAI, and are shared here as illustrative examples of how frontier AI is supporting use cases across our teams.
Ultrafast is a high-speed mode in Codex, and for engineers at OpenAI, it’s become the default for incident response. When something breaks, engineers often don’t have time to wait minutes for an answer while the issue compounds. With Ultrafast, they can investigate multiple potential causes at once and get answers without splitting their attention.
Aaron Friel, Member of the Technical Staff at OpenAI, is usually the one running point on an incident. He spins up a Slack channel for incident response and then points Codex at the problem, asking Codex to monitor, investigate, and answer any questions as they come in. “In any incident, there are usually many hops along the way of what could have gone wrong, and finding the right needle in the right haystack is really the chief job of the people on that channel,” he says. “Using Ultrafast, I’m able to essentially search all of those haystacks at the same time, and respond to incidents much faster.”
AJ Trbojevic, Member of the Technical Staff and a Datacenter Security Architect, says investigations into security issues used to take an hour or two to pull structured and unstructured data together, normalize it, and provide context to make a decision. “Now that happens in 10 to 15 minutes,” he says. “And at times it’s near real time.”
Adam Perry and Sayan Sisodiya both work on the core agent team, building the code that lets Codex take actions, run commands, and use tools. Ultrafast has changed how they operate during security incidents. “Before, I’d ask Codex to look into something, and then go look into it myself at the same time, because I knew it wouldn’t be fast enough to just wait on,” Adam says. “Now with Ultrafast, Codex is fast enough that I can just stay focused instead of splitting my attention.”
Sayan appreciates how Ultrafast lets him get immediate answers from multiple data sources: “Beyond just digging through logs in an incident, I use Codex to dig through Slack to see if there are references to changes that might be suspect or people talking about similar symptoms elsewhere in Slack,” he says.
If it takes more than 30 seconds to find an answer with AI, Jeff Niu, another Member of the Technical Staff, says he’ll check Slack or chat with a coworker. But most of his work is now under that threshold with Ultrafast. He used to ask Codex a question, switch over to something else while it thought, and come back having lost his train of thought. Now that conversation happens in real time; it helps him stay focused on the task at hand.
Ultrafast also makes Jeff more willing to tackle large refactors, because reworking existing code takes less time. “Technical debt is much easier to pay down now than it ever was before,” he says. “Code is cheap, and now it’s very quick to produce. A refactor that used to cost a lot happens almost instantly.”
Adam keeps a running Codex thread that he calls his chief of staff. Every morning it tells him what meetings he has and which messages he might have forgotten to reply to. “It’s already looked at all the data to write that summary, so when I ask a followup, it’s not waiting to go fetch more,” he says. “I can just keep asking questions in the same conversation just like an actual chief of staff.”
Sayan uses Codex to do tedious manual work in the browser, like filling out forms—something he’d previously avoided because it was too slow. “It would open a browser, sit there thinking for five seconds, click something, sit there again,” he says. With the latest models’ improvements in computer use, he’s more comfortable letting Codex handle that work. “Now I’m totally fine letting it click through the browser and it’s fast enough that I’m not losing time by not doing it myself.”
Across incident response, daily planning, and refactoring, Ultrafast lets OpenAI’s Technical Staff work with Codex at the pace of their questions. They can follow up on an answer, try another approach, and keep working without losing their train of thought. That shorter wait also changes what they’re willing to take on, from a refactor they’d put off to a routine task that’s finally worth delegating.
