Open source AI and frontier labs occupy different market phases

Anthropic and other frontier labs aren't competing directly with open source models like Llama because they serve different deployment stages: proprietary systems dominate initial capability breakthroughs and premium use cases, while open source captures the commodity and self-hosted tier after capabilities commoditize. This division of labor insulates Anthropic's business model from open source competition in the near term, but establishes a clear trajectory where today's frontier innovations become tomorrow's freely available tools.
