AI Weekly Issue #521: The frontier just split into three markets

Frontier AI is no longer one market with one scoreboard. This week's release wave exposed a contest between three kinds of leverage: controlling access to intelligence, owning the model outright, and deciding which model receives each job. That changes what winning means. The lab with the highest benchmark score may not control deployment. The model installed most widely may not collect the most revenue. And the most powerful company may be the intermediary quietly directing demand. This issue follows where that leverage is moving, from model distribution into training-data provenance, electricity markets, and government oversight.
