OpenAI is rolling out its cybersecurity testing tool, GPT-5.5 Cyber, but only to critical cyber defenders at first. This decision comes after OpenAI's previous criticisms of Anthropic for limiting access to their Mythos tool. The selective release raises questions about access and utility in cybersecurity.

OpenAI has announced that its new cybersecurity testing tool, GPT-5.5 Cyber, will initially be available exclusively to key cyber defenders. This move echoes a prior critique the company made against Anthropic for restricting access to its Mythos tool. By limiting access to a select group, OpenAI aims to ensure that the cybersecurity tool is used effectively by those most capable of leveraging its capabilities. The decision is significant in the context of ongoing discussions about the role of AI in cybersecurity, highlighting concerns about accessibility, security, and the ethical implications of AI in sensitive domains. Such selective rollout strategies can influence the pace of innovations in AI and cybersecurity.
