So much breathless hyperbole this week about Anthropic's Mythos, no doubt ignited by genius way the company marketed it with elite access and bold unproven claims. @lilyhnewman does good job examining the hype and where it might also prove to be true https://www.wired.com/...

A growing number of people are wondering if Anthropic is the AI industry's “boy who cried wolf.” If Mythos-related threats don't materialize, the company will have a serious credibility problem.

We've been tricked, again. Many of the thousands of bugs and vulnerabilities Mythos found are in older software are impossible to exploit. And the severe zero-day reports rely on just 198 manual reviews https://www.tomshardware.com/ ...

NEW: Just because the most annoying people alive claim Mythos is a harbinger of the end of days doesn't mean it isn't a big deal; the nature of that big deal, though, isn't necessarily as the hype would have it. Level-headed @lhn.bsky.social reports:

this probably exposes my unhinged optimism — but this didn't have to be the case, and is only the case because Anthropic places altruism above profit — it's likely that both OpenAI and Google have private models of roughly equal capabilities to Mythos — Anthropic doesn't have…

everyone talking about claude mythos like it's the biggest model ever and will be insanely expensive to run, but gpt 5.4 pro is already publicly available and costs significantly more. there are actually 4 benchmarks in common: it's a tie on gpqa, mythos is much better at HLE, [i…

Anthropic's new model, Claude Mythos, is so powerful that they're not releasing it. They must have good reasons. They're willing to forgo a lot of revenue. @robertwiblin on what we know so far about how dangerous the current situation is. https://80000hours.org/...

Couple thoughts re: the Sam/Molotov cocktail thing and the wider issue of AI-related violence: 1. Most importantly, I'm glad no one got hurt. Besides the basic human perspective of “murder bad,” political violence is always bad, as is techno-political violence or whatever this

I would say there's a 20% chance that the molotov cocktail attack on Sam Altman's house was a FALSE FLAG to play victim after all the damning revelations from @RonanFarrow and the mogging from Anthropic on every dimension. Also, whenever Sam is in trouble he's posting his baby [i…

Small banks and credit unions aren't built for this threat model. Most run on 1-2 outsourced cyber teams. That doesn't stand a chance against even high end open source models in adversarial mode.

Every single person saying “Anthropic made up mythos,” despite *JP Morgan* and many others being clearly concerned about it, is perfectly fulfilling this prediction. They think “perceiving AI models as highly capable” is an EA perversion intended to attain “regulatory capture.”
