Claude Mythos

Type: Model

Overview

Claude Mythos is a leaked, unreleased Anthropic model described as a step-change in performance, dramatically outperforming current models on reasoning, coding, and cybersecurity. A configuration error in Anthropic's CMS accidentally exposed draft materials, causing markets to reprice—software ETFs fell 3%, Bitcoin tumbled—before the model was even available. The speaker uses Mythos as the clearest illustration that arbitrage windows now shift overnight with model announcements, not deployments.
