Anthropic has not in fact released it, and it does in fact appear to be that dangerous, judging by the flood of vulnerability reports seen by e.g. Daniel Stenberg. Certainly it’s a strategy OpenAI has used before, and when they did so it was a lie. Altman’s dishonesty does not mean it can never be true, however.

I do not think you need a great model to do this, just great automation. There’s a reason they haven’t open sourced the actual process in which did this, stubbing out the mythos model itself.

About five minutes in in this video: https://www.youtube.com/watch?v=1sd26pWhfmg They also say publicly in their Opus 4.6 post ( https://red.anthropic.com/2026/zero-days/ ): >In this work, we put Claude inside a “virtual machine” (literally, a simulated computer) with access to the latest versions of open source projects. We gave it standard utilities (e.g., the standard coreutils or Python) and vulnerability analysi…

> judging by the flood of vulnerability reports seen by e.g. Daniel Stenberg Maybe I've missed anything, but what Stenberg been complaining about so far been the wave of sloppy reports, seemingly reported by/mainly by AIs. Has that ratio somehow changed recently to mainly be good reports with real vulnerabilities?

Side note, how did the word "lose" become "loose"? I've seen this so many times on HN.
