OpenAI and Anthropic find common ground: Open-weight AI

OpenAI and Anthropic have jointly engaged in Washington to warn policymakers about the risks of open-weight AI models. The two companies, which have often been at odds over safety approaches, are now aligned on the potential dangers of widely accessible AI systems. Additionally, OpenAI has endorsed a Massachusetts AI safety bill.

The companies are urging lawmakers to consider the implications of open-weight models, which can be freely downloaded and modified. The Massachusetts bill, which OpenAI explicitly endorsed, would impose safety requirements on AI development in the state.

The lobbying effort reflects a shift in the AI industry's regulatory stance. Policymakers in Washington and state capitals are increasingly focused on AI governance.
