AI heist or hype leak?
MythosWatch: Tracking who has access to Anthropic's Mythos AI
Leaked AI, secret NSA access, and a Discord backdoor have the internet yelling “who’s really in charge here”
TLDR: A private group reportedly slipped into Anthropic’s restricted Mythos AI through a vendor system, even as agencies like the NSA quietly get official access. Commenters are split between calling it a major trust and security failure and laughing that AI has turned into an exclusive nightclub for governments and hackers.
Anthropic’s secretive “Mythos” AI preview was supposed to be invite-only, but the internet is having a field day after reports that a small, unauthorized group snuck in through a third‑party vendor and showed it off on a private Discord. Cue instant drama: some users are calling it an “AI heist,” others say it’s just a glorified password screw-up. When people saw that the NSA (yes, the spying agency) is listed as having access while the Pentagon is legally barred, comment sections basically melted. One camp is posting memes of the NSA in sunglasses saying, “Nice AI you’ve got there.” Another is side‑eyeing Anthropic for having 40+ undisclosed partners and asking, who exactly is playing with this thing?
Privacy‑focused users are furious that shadowy groups and intelligence agencies might be poking around a powerful AI tool while regular developers are stuck outside the fence. Meanwhile, more cynical commenters are joking that the “unauthorized users” are just Mythos’ unintended beta testers, working for free. Others defend Anthropic, saying leaks happen and at least the core systems weren’t hit. The loudest fight: is this a serious security red flag or just normal growing pains for cutting‑edge tech? Either way, people agree on one thing — AI access has officially become the hottest VIP list on the internet.
