OpenAI and Google Signed the Letter Championing Open AI Security — But Haven't Joined the Alliance It Created

OpenAI and Google signed the open letter urging the White House to support open source AI that gave rise to the alliance. The three firms building the most capable closed frontier models are absent from an effort focused on securing open AI systems.
