Anthropic, currently the world's most valuable AI company with a $1.2 trillion valuation on secondary markets as of earlier this month, offers products including Claude.ai, Claude Code, and Claude Cowork, as well as LLMs named Haiku, Sonnet, Opus, Fable, and Mythos. The US government temporarily banned use of Anthropic's Fable model because it was "just too smart and risky for our own good." The article uses a car analogy to explain the offerings, comparing the choice of vehicle model to selecting between Claude.ai, Claude Code, and Claude Cowork, and the choice of engine size to selecting between Haiku, Sonnet, Opus, Fable, and Mythos.
