The U.S. AI Safety Institute (AISI) may be dismantled if Congress fails to authorize its existence. Established in November 2023 under President Biden's AI Executive Order, the AISI is crucial for assessing AI safety. A coalition of over 60 organizations, including OpenAI and Anthropic, urges Congress to pass legislation for its continuation. Current funding is around $10 million, but authorization could secure long-term financial support. Concerns arise that disbanding the AISI could hinder U.S. leadership in AI, especially as international collaborations emerge.
