  great video let me tell you how Mythos affects crypto: > companies ("labs") that are serious about their dapp's code and by extension their livelihood will pay to get these bugs found > cost socialization will happen by governance tokens being dumped (yet again) > nothing new

  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, a…

  This video is absolutely hilarious because there are literally thousands and thousands of people who happily opened a gaping hole for Remote Code Execution on their main devices over the last 3 months. You know - the type of security vulnerability that the researcher in video

  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/...

  Anthropic: Mythos is too good, it'll be dangerous to release it.  Also Anthropic: buggy code, only 98.7% uptime.  Also Anthropic: Claude Mythos Preview was made available for internal use on February 24... ...and their reliability has gotten worse since 24th February.  Can we jus…

  Absolutely brilliant video. He's completely correct too. I previously said no one found it because no one was looking. I didn't know what the issue was and that it likely wasn't even exploitable. So I guess this is yet again marketing to try to get people to pay for expensive AI.

• @maxcroser Max Roser on x

  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/...

• @emollick Ethan Mollick on x

  I am catching glimpses in my feed that there is a backlash against Mythos as “marketing hype,” and it is a little confusing. I don't think anyone who has used the latest agentic coding tools, would think that expecting large-scale cybersecurity implications of increasingly good

• @davidsacks David Sacks on x

  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.

• @ramez Ramez Naam on x

  There does seem to be an anti-Claude vibe shift. As someone who has tweeted reasons to believe Mythos is mostly a continuation of current trends, I want to clarify that: 1. The cyber security implications look major and quite important. 2. I applaud what Anthropic is doing with

• @adxtyahq Aditya on x

  Anthropic will say whatever it takes to stay in the headlines. Claude Mythos claims “thousands of vulnerabilities” off just ~198 reviewed cases • only ~198 reports actually reviewed • “thousands” comes from extrapolation • some bugs weren't even practical to exploit • some [image…

• @robertwiblin Rob Wiblin on x

  I spent the last 2 days trying to figure out how scary Claude Mythos is.  I think it's fairly scary, though not because of the hacking: 1.  It indicates fully-automated AI R&D is coming sooner 2.  Its alignment seems better, which is good.  But all the alignment tests have seriou…

• @andrewcurran_ Andrew Curran on x

  There has been a great deal of speculation about why Anthropic is keeping Mythos in restricted release. One of the least-discussed reasons is cost. Not the cost to Anthropic of serving the model, but the downstream effects that cost will have on the industry, and on the world.

• @maskedtorah Drake Thomas on x

  Hey!  I work at anthropic and helped organize the writing of the mythos preview system card.  I can't speak to the insides of other people's heads, but for what it's worth, it is my very very strong impression that the public announcement was motivated overwhelmingly by a desire …

• @jeffreyleefunk Jeffrey Lee Funk on x

  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/ ...

• @littmath Daniel Litt on x

  Curious how much (if at all) the anti-Claude hedonic treadmill tweeting is being amplified by Elon. Seems to have really taken over my timeline, at least.

• @timkellogg.me Tim Kellogg on bluesky

  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…

• @timmarchman Tim Marchman on bluesky

  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:

  “So, basically, if Anthropic was not a US company, we'd be facing zero days with multiple unknown points of attack on virtually all of our systems to an adversary who developed this capacity before us.”  [embedded post]

  Anthropic Mythos is so dangerous > spending $20k on tokens > find bug on a 15-20y old code > never a bug bounty over $1k Shocked to find bugs in code bases nobody ever gave a fuck about
