\t\t\t\t\t\t\t\t\t\t Can\u2019t-miss innovations from the bleeding edge of science and tech<\/p>\n

As companies continue to burn through billions of dollars by running massively resource-hungry AI models \u2014 and only passing on a fraction of the costs to consumers and enterprise clients \u2014 the AI race shows no signs of slowing down.<\/p>\n

On Thursday, a data leak caused by a major security lapse in its public-facing content management system revealed that Anthropic is working on a powerful new model release.<\/p>\n

The company has since officially acknowledged the new project, dubbed \u201cClaude Mythos,\u201d with a spokesperson describing it to Fortune as a \u201cstep change\u201d in AI proficiencies and the \u201cmost capable we\u2019ve built to date.\u201d<\/p>\n

The spokesperson said it\u2019s a \u201cgeneral purpose model with meaningful advances in reasoning, coding, and cybersecurity.\u201d<\/p>\n

In an enormously ironic twist, a draft blog obtained by Fortune, which was \u201cavailable in an unsecured and publicly-searchable data store,\u201d claimed that the new model \u201cposes unprecedented cybersecurity risks.\u201d In other words, let\u2019s hope the new model wasn\u2019t responsible for the security of Anthropic\u2019s company blog.<\/p>\n

It\u2019s a major test for the company, which has received significant media attention as of late for its Claude Code and Claude Cowork tools, the successes of which appear to have rattled Anthropic\u2019s competitors, including OpenAI, to their core.<\/p>\n

The leaks also revealed a \u201cnew tier\u201d of AI models, dubbed Capybara. Mythos appears to be part of this new tier, but how Capybara fits in with Anthropic\u2019s existing tiers \u2014 Opus, Sonnet, and Haiku, in decreasing size, capability, and cost \u2014 remains to be seen.<\/p>\n

\u201cCompared to our previous best model, Claude Opus 4.6, Capybara gets dramatically higher scores on tests of software coding, academic reasoning, and cybersecurity, among others,\u201d the leaked blog reads, as quoted by Fortune.<\/p>\n

While it may score higher in cybersecurity tests, it could simultaneously represent a major challenge for existing cybersecurity defenses, the company warned.<\/p>\n

\u201cIn preparing to release Claude Capybara, we want to act with extra caution and understand the risks it poses \u2014 even beyond what we learn in our own testing,\u201d the company wrote in the leaked blog post. \u201cIn particular, we want to understand the model\u2019s potential near-term risks in the realm of cybersecurity \u2014 and share the results to help cyber defenders prepare.\u201d<\/p>\n

The model \u201cpresages an upcoming wave of models that can exploit vulnerabilities in ways that far outpace the efforts of defenders,\u201d Anthropic boasted.<\/p>\n

The risks appear to have been real enough for cybersecurity stocks to plunge on Friday, following the latest news.<\/p>\n

Anthropic has also previously admitted that hackers used its Claude AI model to automate cybercrimes targeting banks and governments. According to the company\u2019s November blog post, a Chinese state-sponsored group exploited the AI\u2019s agentic capabilities to infiltrate \u201croughly thirty global targets and succeeded in a small number of cases\u201d by \u201cpretending to work for legitimate security-testing organizations\u201d to sidestep Anthropic\u2019s AI guardrails.<\/p>\n

Reality check: a frontier AI company is working on what it claims to be the next big thing that\u2019s more capable than anything that\u2019s come before it is pretty standard fare, and it remains to be seen whether Claude Mythos will actually represent a major \u201cstep change\u201d in practice, outside of a carefully curated testing environment.<\/p>\n

Case in point, OpenAI\u2019s long-awaited GPT-5 model turned out to be a major letdown when it was released in August, falling well short of the company\u2019s lofty promises.<\/p>\n
