It’s been only two days since the bombshell news about Claude Mythos broke, and Anthropic can’t wait any longer!<\/p>\n

Today, some developers shared screenshots that shocked the entire internet \u2014<\/p>\n

The internal testing of Claude Mythos 5.0 Beta has begun<\/strong>, and it has appeared in both Claude and Claude Code.<\/p>\n

\n

In the Claude interaction interface, Mythos 5.0 (Beta) is prominently listed, and the official describes it as “larger in scale and more intelligent<\/strong>.”<\/p>\n

In the Claude Code terminal, Mythos 5 is directly titled as the “next-generation model.”<\/p>\n

<\/p>\n

<\/p>\n

Some authoritative sources revealed that the performance of Mythos 5.0 is “brutal.”<\/p>\n

Its capabilities in programming, logical reasoning, and offensive security (testing network defense vulnerabilities) are incredibly powerful.<\/p>\n

<\/p>\n

<\/p>\n

Now, the “draft blog post” that caused a stir across the internet has finally been confirmed!<\/p>\n

<\/p>\n

The internal testing of Mythos 5.0 has begun, shocking the entire internet<\/strong><\/h2>\n

In this “draft blog post” archived by an internet celebrity, Claude Mythos (code-named Capybara) is regarded internally as the “highest-level” AI.<\/p>\n

<\/p>\n

It is a brand-new “top-tier” model that is larger in scale, more intelligent, but also more expensive than the most powerful Opus.<\/p>\n

Just 48 hours after the leak, Mythos 5.0 has already started the gray-scale testing.<\/p>\n

<\/p>\n

<\/p>\n

<\/p>\n

Now, on Polymarket, people are starting to predict its release time: There is a 73% chance that it will be launched in June<\/strong>.<\/p>\n

<\/p>\n

In fact, the internal training of Mythos 5.0 has already been completed.<\/p>\n

The only reason why Anthropic has been holding back is that it is too powerful and too dangerous.<\/p>\n

In terms of network security, Mythos 5.0 has achieved a generational leap, but it must be admitted that Opus 4.6 is already quite impressive.<\/p>\n

Claude cracked the Linux kernel in 90 minutes, going wild<\/strong><\/h2>\n

Just today, Claude independently discovered a “zero-day vulnerability,” shocking the entire Silicon Valley.<\/p>\n

At the [un]prompted conference in San Francisco, a live demonstration by Nicholas…<\/p>\n
