Anthropic, the artificial intelligence company behind Claude, has begun testing a new AI model that is better than any it has previously released, Fortune reported.
The company said the model represents “a step change” in performance and is “the most capable we’ve built to date.” It is currently being tested with a small group of early access customers as Anthropic assesses its behavior and risks.
Among the names moving down sharply in the news: Palo Alto Networks ( PANW ), Crowdstrike ( CRWD ) and Fortinet ( FTNT ) are all down 4%-6%. The broader iShares Expanded Tech-Software Sector ETF ( IGV ) is down 2.5%.
The overnight leak likely contributed to bitcoins falling back to $66,000 after flirting with $70,000 hours earlier.
Details about the model emerged after internal materials were accidentally exposed in a publicly available data repository, according to Fortune. About 3,000 assets linked to Anthropic’s blog were available online, including draft announcements and internal content that had not yet been released.
Among the files was a draft blog post referring to the model as “Claude Mythos.” The document warned that the system could pose serious cybersecurity risks, pointing to its ability to identify and exploit software vulnerabilities.
Anthropic currently offers three tiers of models – Opus, Sonnet and Haiku – which vary in size, price and capacity. The leaked materials suggest that the company is developing a new tier called “Capybara”, which would be even bigger and more intelligent than the Opus, the company’s most advanced model to date.
