do you read the diaries of your AI agents?













We replicated Mythos findings in opencode using public models, not Anthropic's private stack. The moat is moving from model access to validation: finding vulnerability signal is getting cheaper; turning it into trusted security A better way to read Anthropic's Mythos release is not "one lab has a magical model." It is: the economics of vulnerability discovery are changing. We took the patched public Mythos examples and tried to reproduce them with GPT-5.4 and Claude Opus 4.6 in an open-source harness. Every run stayed below $30 per file. AI models are already good enough to narrow the search space, surface real leads, and sometimes recover the full root cause in battle-tested code. The takeaway: model access is not the moat anymore. Validation is. Finding vulnerability signal is getting cheaper; turning it into trusted security work is still hard.

Why does Anthropic have such hardass licenses for even their skills lol Meanwhile most Codex skills are Apache 2.0
