🚨 SOURCES: ANTHROPIC IS ABOUT TO RELEASE A PUBLIC VERSION OF MYTHOS. Mythos is the model Anthropic said was too dangerous to release. It can hunt down critical software flaws and build working cyberattacks on its own. Until now only a locked circle could touch it: Apple, Google, Microsoft, JPMorgan, NVIDIA. Per Sources, the public version is finally coming, once the safeguards are in place. The model they called too dangerous to ship is about to go mainstream.

Claude Mythos / Oceanus is insane see the level of detail using Three.js (from jsDelivr).HTML and a custom meshing engine it made (in like 5 minutes and low effort thinking level) Credit to Lentils and z..AI , this is so good people are not realising it yet 😭

$AMZN AWS CEO said Anthropic’s latest models are being trained on Trainium (including Mythos) which Anthropic describes as its most capable model yet. That is notable because Anthropic is limiting Mythos due to cybersecurity risk & high compute costs which says a lot about the kind of model Amazon’s chips are now helping train.

Anthropic CEO: “At Anthropic, we essentially have Claude designing the next version of Claude itself.” Meanwhile, Anthropic says every new model is given code that trains a small AI model and asked to make it faster. Claude Opus 4 achieved a 3x speedup. Mythos Preview reached 52x. Recursive self-improvement is starting to look real The models are helping build what comes next.

David Sacks on How Anthropic is Ironically Running Surveillance on Their Latest Models “This is the company that said that it was against government surveillance. They are now retaining for 30 days every prompt and every output you send to one of these Mythos class models.”

"You should have to own a GUN LICENSE to use it. Please don’t release this." that’s what early testers told Anthropic about Mythos 💀 the hype around this thing is getting ridiculous.

#WATCH | California, USA: On Anthropic Mythos, CEO of Blackstraw AI, Atul Arya says, "...Anthropic has released a reasoning model called Mythos... Unlike standard AI, it explains the 'why' behind its answers. Its primary initial use case is cybersecurity... helping companies identify not just where vulnerabilities exist, but why they occur. Currently, Mythos provides its testing early version to 20 major firms like Microsoft and CrowdStrike... to both simulate and prevent attacks... it's in its early phase... this model is powerful... and will be very useful in future..." Speaking about its impact on the banking industry, he says, "It can be both a threat and helpful... If someone wants to do something wrong, they'll attack the bank... According to me, for the banking industry, it is not a matter of worry. But yes, it is definitely a matter of caution as to what can happen with this and early adoption means adopting it in advance and reaching a stage when it is used in general availability..." On India's banking system's preparations for Mythos, he says, "...What's happened in India is that a large generation has acquired banking access directly on mobile phones, having never seen anything else, including a laptop... Even if we provide this only to banking systems, they are only halfway to success... The remaining 50% depends on public education. In a nation where 60-70% of people live in rural areas, educating users not to click suspicious links or share credentials is critical..."

Anthropic's newest AI model, called Mythos, is so powerful, the company says, that it could cause widespread disruption if it's released to the public. For now, Anthropic is giving more than 40 tech companies, including some rivals, access to Mythos to test it and identify vulnerabilities across systems. But that move is raising concerns. Watch Geoff Bennett's conversation with Gerrit De Vynck 🦭.

For the past 2 months, XBOW has been testing Mythos Preview under embargo as part of a select early-access group. Today, we can finally share what we found. The headline: Mythos Preview is a major advance. It is substantially better than prior models at finding vulnerability candidates, especially when source code is available. But it’s not perfect. We surfaced issues with exploit validation, judgment, and efficiency. Our full write-up covers where Mythos Preview shines, where it still needs support, and what we think this means for the future of offensive security:

🚨 ANTHROPIC JUST REVEALED CLAUDE MYTHOS ABILITIES Anthropic just formally announced "Claude Mythos Preview" and launched "Project Glasswing" to deploy it for cybersecurity defense. The models are unlocking completely new, autonomous behaviors. This isn't about slightly better benchmark scores. This is about what the model can do. Here are the direct quotes from Anthropic’s research team (including Dario) on exactly what Mythos is capable of: • Chaining Exploits: "It has the ability to chain together vulnerabilities... this model is able to create exploits out of three, four, sometimes five vulnerabilities that in sequence give you some kind of very sophisticated end outcome." • The Professional Standard: "The model that we're experimenting with is, by and large, as good as a professional human at identifying bugs." • Unprecedented Autonomy: "It's just generally better at pursuing really long-range tasks that are kind of like the tasks that a human security researcher would do throughout the course of an entire day." The Reality Check: Dario Amodei flat out said: "There's a kind of accelerating exponential... Claude Mythos Preview is a particularly big jump along that point." Because this model has become so capable at identifying zero-days, they are restricting its release to top tech partners to try to patch the world's software before these capabilities leak out. The autonomous researcher era has officially arrived. It’s over 💀

FREE CLAUDE FABLE 5 and almost nobody knows this trick Anthropic recently released their most capable model ever - the first Mythos-class model available to the public normally it's $10/$50 per million tokens but there's a hack: GitLab just added Fable 5 to Duo Agent Platform - across ALL tiers, including free trial the setup: 1/ register a GitLab account: 2/ start the free GitLab Duo trial 3/ Fable 5 is live through their AI Gateway 4/ done - Mythos-class model, $0 why Fable 5 is worth the hype: 1/ 80.3% SWE-Bench Pro - 11 points ahead of the next best model 2/ multi-DAY autonomous runs without losing the plot 3/ single-pass implementations of systems that took days of iteration 4/ Karpathy called it 'a major-version-bump-deserving step change' also free on Claude Pro/Max/Team until June 22 - after that it's usage credits you have a limited window to run the most capable public model on the planet for FREE

On the Mythos Preview, swyx thinks Anthropic are too good at marketing, and may be overdoing it. "I think just let your competence shine through. They're amazing. It's a beautiful model. You don't have to be so dramatic". "You don't have to produce a five-minute polished video of the CEO of every security company on earth saying you're the greatest thing since sliced bread." "There was a little bit too much marketing buzz around the drama of like, 'oh, my Mythos just texted me while I was eating a sandwich".

Another impressive and early Claude Mythos output for y'all. 😀 I literally just told it to generate a macOS clone and to do its absolute best. It generated 50k tokens (3k lines of code), made a fully functional browser, made a music player with generated songs and added a lot of sneaky witty details. AND this is also LOW effort!

🚨Anthropic puts Mythos in a locked sandbox and told it to try escaping. it did. it chained multiple vulnerabilities together, broke out of containment and reached the open internet. the model also emailed the researcher to say it got out. > the researcher found out while he was eating sandwiches in the park after he received a random email. Anthropic is now so scared of what Mythos can do offensively that they won’t release it publicly. in response they’re launching Glasswing, a coalition with Apple, Google, Nvidia and 40+ more companies to use Mythos only for defense. the model found “thousands” of zero-days across all OS and browsers is being locked behind a defensive wall because if it ever got out, nobody could predict what comes next. yes we’re at this point. and we only know about this because a guy got an email while eating a sandwich.

This is big... Anthropic just announced a model so powerful they won't release it to the public out of fear over the damage it will cause 😨 Claude Mythos Preview found thousands of zero-day exploits in every major operating system and web browser... The numbers are hard to believe: > $50 to find a 27-year-old bug in OpenBSD, one of the most security-hardened operating systems ever built > Under $1,000 to find AND build a fully working remote code execution exploit on FreeBSD that grants unauthenticated root access from anywhere on the internet > Under $2,000 to chain together multiple Linux kernel vulnerabilities into a complete privilege escalation exploit For context: these are the kinds of findings that previously required elite security researchers working for weeks. Anthropic engineers with no formal security training asked Mythos to find exploits overnight. They woke up to working code the next morning. The results were so impressive Anthropic assembled Apple, Google, Microsoft, Amazon, NVIDIA, and seven other organizations into Project Glasswing: A $100M defensive coalition. They're not releasing this model publicly. Instead, they're racing to patch the world's infrastructure before models like this proliferate.
