Here's what next as Anthropic's most powerful AI model leaked via unsecured data cache
Anthropic's powerful new AI model, Mythos/Capybara, was accidentally leaked via an unsecured data cache, revealing unprecedented cybersecurity risks.Summary
Anthropic's highly capable new AI model, internally named "Mythos" and designated as the "Capybara" tier, was accidentally revealed through a draft blog post left in an unsecured, publicly searchable data cache. The company confirmed the existence of this model, which it describes as its most powerful yet, noting it achieves dramatically higher scores in coding, reasoning, and cybersecurity tests compared to its previous best model, Claude Opus 4.6. The draft specifically flagged that the model "poses unprecedented cybersecurity risks," which has significant implications for blockchain security and DeFi. The leak highlights the irony of a company developing advanced cybersecurity AI failing to secure its own announcement. Anthropic stated the model is currently being trialed by early access customers, is expensive to run, and is not ready for general release; the company removed public access to the cache after being contacted by Fortune.
