According to Fortune, the decline appears to be related to news of a leak concerning Anthropic’s latest AI model before its release, with relevant descriptions stored in a publicly accessible data cache. Details of the new model, codenamed “Claude Mythos,” were reportedly stored in an unencrypted and publicly searchable data repository in a blog draft.

The AI startup blamed the leak on “human error” in its content management system configuration. The leaked draft introduced a new tiered AI model named “Capybara,” which will be larger and more powerful than Anthropic’s current top Opus model.

According to the leaked documents, Capybara scored higher than Claude Opus 4.6 in software programming, academic reasoning, and cybersecurity-related tasks. The draft described Claude Mythos as “the most powerful AI model we have developed to date.”

An Anthropic spokesperson told Fortune that the company is “developing a general model that makes significant advancements in reasoning, programming, and cybersecurity,” and is “carefully considering how to release it.”

The blog draft reportedly warned that the model “far surpasses any other AI model in terms of cybersecurity capabilities,” potentially triggering “a wave of models that can exploit vulnerabilities far exceeding the efforts of defenders.”
