  "account": "Anthropic has upgraded its Claude Security vulnerability scanner with the integration of its Claude Mythos 5 model. This comes as part of a major enhancement to the service that aids development teams in identifying and addressing security vulnerabilities within their codebase. In addition to this upgrade, Anthropic is collaborating with other cybersecurity firms to facilitate integration of Mythos 5 into their products. To support this effort, Anthropic is launching a new Defender Advantage Fund, offering $35 million in credits to assist in the discovery and patching of vulnerabilities within open source software. Earlier, Anthropic announced the Cyber Verification Program, enabling approved cybersecurity professionals to work with both Opus and Sonnet models for dual-use cybersecurity tasks, with Claude Mythos access becoming available soon to vetted organizations. The process behind Mythos 5 is noteworthy, as it was initially not made publicly available due to its high-performance capabilities in high-risk domains. However, Anthropic has deemed it safe to integrate into Claude Security now, as users can only receive specific outputs, such as patches or security alerts, instead of direct model access. This approach significantly reduces the risk of malicious actors steering the model towards harmful uses. Safeguards are in place within Anthropic's tools to ensure the model remains within its intended scope. As Mythos 5 now operates in public beta for Claude Enterprise users, Anthropic charges $10 per million input tokens and $50 per million output tokens.",
