Toasted to a respectable shade. No regrets, no crumbs left.
Summary
Frontier AI labs like Anthropic and OpenAI are shifting toward a strategy of selective access for their most advanced cyber-capable AI models. Rather than fully open or fully restricted releases, they are creating trusted-access programs that give certain defenders privileged use of cutting-edge cyber capabilities. This positions AI companies as new power brokers in cybersecurity, deciding who gets access to the most powerful tools. Anthropic recently announced public availability of its Fable 5 model (part of the Mythos class), while also developing a formal trusted-access program.
