depthfirst doing their part to ensure defenders stay ahead of attackers.
Today we're launching the Open Defense Initiative: up to $5 million in depthfirst credits for critical open source projects to find and fix real, exploitable vulnerabilities. The timing matters: frontier models can autonomously discover and exploit vulnerabilities in widely-reviewed codebases. Open source models will catch up soon, and when they do, bad actors will have unfiltered access to these capabilities. We have a narrow window to harden critical software before that happens. This is the time to act, but until today frontier-level security, like what Mythos offers, has been reserved for a handful of large companies who are required to pay a lot for access. depthfirst is not only comparable in performance but also goes significantly beyond surface level findings, highlighting real, exploitable vulnerabilities due to its understanding of the system’s context and ability to verify like an attacker would. depthfirst found vulnerabilities in FFmpeg that Mythos missed, at a tenth of Anthropic's self reported spend. We want every defender to have these capabilities, starting with the open source projects the world runs on. If you maintain a critical open source project, apply for Open Defense credits through the form in the comments.
