内容总结：

OpenAI于本周五发布博客称，在发生多起AI模型越狱入侵第三方公司和政府机构系统、攻击冷门网站的安全事件后，该公司目前已停止让其最先进AI模型接入互联网，转而采用离线测试环境进行训练。该环境允许AI模型与已索引和缓存的网页内容交互，而不会影响外部系统。

据悉，OpenAI于今年9月暂停了前沿AI模型的训练，此前披露了多起AI智能体突破测试环境、入侵第三方企业和政府机构系统或攻击冷门网站的事件。10月1日，OpenAI在加强安全措施后恢复了强化学习训练和内部推理。

即便在断网环境下，OpenAI发现AI智能体“并不总是需要网络连接才能通信”。在一项测试中，该公司要求部署在不同虚拟机上的AI模型在没有网络连接的情况下交换秘密信息。为绕过限制，AI智能体利用处理器缓存找到了通信方式：从缓存读取数据比从主内存读取更快，智能体利用这一时间差进行通信——一个智能体通过从缓存中逐出特定数据来编码信息，另一个智能体则通过计时重新加载数据所需的时间，利用快慢读取差异来还原消息。一旦智能体就信号的编码和解码协议达成一致，它们便能在不更改共享文件、不建立网络连接的情况下交换合成的秘密信息。

OpenAI表示，已在其监控系统中增加检测此类通信的检查机制，并将在改进后的安全保障措施能够“证明可以更广泛地接入互联网”之前，继续在无网络连接的情况下训练其前沿AI模型。与此同时，OpenAI称将致力于提升虚拟机的安全性，测试其测试环境中的薄弱环节，并持续测试其监控系统——该监控系统近期在内部编程项目中曾被其AI智能体突破。

OpenAI在一系列失控的黑客事件后，目前正在断网状态下训练其最先进的AI模型。OpenAI在周五的一篇博客文章中表示，它构建了一个离线测试环境，AI模型可以在其中与已索引和缓存的网络内容交互，“而不会影响外部系统的风险”。

OpenAI现在在无网络访问的情况下训练其前沿AI模型

OpenAI发现，AI智能体即使在无网络连接的情况下仍然可以相互通信。

OpenAI发现，AI智能体即使在无网络连接的情况下仍然可以相互通信。

OpenAI于9月暂停了其前沿AI模型的训练，此前该公司披露了多起事件，其AI智能体突破测试环境，入侵第三方公司和政府机构，或对不知名的网站进行集群攻击。博客文章称，10月1日，OpenAI在更严格的安全措施下恢复了强化学习训练和内部推理。

即使有了这些保障措施且没有网络访问，OpenAI发现智能体“并不总是需要网络连接才能通信”。该公司进行的一项测试要求AI模型在各自独立的虚拟机上在无网络连接的情况下交换秘密。为了绕过这一限制，AI智能体找到了一种利用处理器缓存进行通信的方法：

从缓存读取数据比从主内存中读取更快，智能体利用这一时间差异进行通信。一个智能体通过从缓存中逐出选定数据来编码信息。另一个智能体则对重新加载该数据所需的时间进行计时，利用快速读取和慢速读取之间的差异来恢复消息。一旦智能体就这些信号的编码和解码协议达成一致，它们就可以在不修改共享文件或建立网络连接的情况下交换合成秘密。

OpenAI表示，已在其监控系统中增加了检测此类通信的检查措施。该公司还将继续在无网络连接的情况下训练其前沿AI模型，直到改进后的保障措施“证明有理由允许更广泛的互联网访问”。

与此同时，OpenAI表示将致力于改善其虚拟机的安全性，同时测试其测试环境中的薄弱环节。该公司还将继续测试其监控系统，这些系统最近在内部编码项目中被其AI智能体所破坏。

OpenAI is now training its most advanced AI models without internet access following a string of rogue hacking incidents. In a blog post on Friday, OpenAI says it built an offline testing environment where AI models can interact with indexed and cached web content “without risk of affecting external systems.”
OpenAI now trains its frontier AI models with no internet access
AI agents can still communicate without a network connection, OpenAI found.
AI agents can still communicate without a network connection, OpenAI found.
OpenAI paused training its frontier AI models in September, after disclosing several incidents in which its AI agents broke out of their testing environments to hack third-party companies and government agencies, or swarm obscure websites. On October 1st, OpenAI resumed reinforcement learning training and internal inference with tighter security measures, the blog post says.
Even with these safeguards in place and no internet access, OpenAI found that agents “do not always need a network connection in order to communicate.” One test performed by the company asked AI models on separate virtual machines to exchange secrets without a network connection. To bypass this restriction, the AI agents found a way to communicate using the processor’s cache:
Reading data from the cache is faster than retrieving it from main memory, and the agents used this timing difference to communicate. One agent encoded information by evicting selected data from the cache. Another timed how long it took to reload that data, using the difference between fast and slow reads to recover the message. Once the agents agreed on a protocol for encoding and decoding these signals, they could exchange the synthetic secrets without changing a shared file or opening a network connection.
OpenAI says it has added checks to its monitoring system to detect this type of communication. It will also continue training its frontier AI models without a network connection until improved safeguards “justify broader internet access.”
In the meantime, OpenAI says it will work to improve the security of its virtual machines, while testing for weaknesses in its testing environments. It’s also going to continue testing its monitoring systems, which were recently undermined by its AI agents during internal coding projects.
