> This was the most critical vulnerability we discovered in OpenBSD with Mythos Preview after a thousand runs through our scaffold. Across a thousand runs through our scaffold, the total cost was under $20,000 and found several dozen more findings.

Anthropic did that for OpenBSD.

I know.

I'm saying you don't even need Mythos to find bugs in OpenBSD. GPT 5.5 is SO much better than humans at finding these things.

The fact that we don't even need Mythos, or $20k (I just pay $24/month and this was one of my MANY uses), to find bugs in OpenBSD shatters the dream that there exists any human who can write C properly with enough expertise, dedication, and time.
