AI 摘要

OpenAI继批评Anthropic限制其AI模型Mythos的访问后，也对其AI模型Cyber实施了访问限制。这一行动表明，尽管OpenAI曾公开质疑竞争对手的限制政策，但其自身在实际操作中也采取了类似措施。目前Cyber的具体访问限制程度和受影响用户范围尚未详细披露，但该事件凸显了AI行业在模型开放与管控之间的普遍矛盾。

After dissing Anthropic for limiting Mythos, OpenAI restricts access to Cyber, too

After Sam Altman trash-talked Anthropic for gatekeeping its cybersecurity tool Mythos by only releasing it to select users, he confirmed that OpenAI would be doing the same with its competing tool, Cyber.

Altman said in a post on X on Thursday that OpenAI will begin rolling out GPT-5.5-Cyber “to critical cyber defenders” in the next few days. OpenAI has an application on its website where people submit information about their credentials and planned use in order to gain access.

This version of Cyber can perform such tasks as penetration testing, vulnerability identification (and exploitation), and malware reverse engineering, the application implies. It’s intended to be a toolkit to help a company find security holes and test defenses. The fear is that the kit could be misused by the bad guys.

When Anthropic similarly restricted access to Mythos, Altman called the tactic fear-based marketing. Some critics also thought so, saying Anthropic’s rhetoric was overblown. Ironically, an unauthorized group reportedly managed to gain access to Mythos anyway.

OpenAI says it’s working to make Cyber more widely available by consulting with the U.S. government and identifying more users with legit cybersecurity credentials.

A spokesperson tells TechCrunch that the company’s system for verifying those with legit cybersecurity credentials, which it calls Trusted Access for Cyber (TAC) has scaled “to thousands of verified defenders and hundreds of teams responsible for protecting critical software.” Those folks can use the latest model, GPT 5.5 for “cybersecurity tasks” with less “friction” from safeguards.

The TAC permissions program is tiered, the spokesperson said: “Critical defenders with legitimate defensive use cases can apply to access dedicated more cyber-permissive models like GPT-5.4-Cyber, and the forthcoming GPT-5.5-Cyber, through the program.”
