The Future of Life Institute’s 2026 AI Safety Index rated Anthropic the highest-scoring of nine major AI companies with a grade of C+, while no firm scored above that mark. OpenAI and Google DeepMind received a C, Meta received a D+, and xAI, DeepSeek and Mistral all received failing grades. The report found that Anthropic, OpenAI, Google DeepMind and Meta have all weakened or dropped earlier pledges to pause development if certain risk thresholds were crossed, and flagged existential safety, covering risks from highly capable or self-improving systems, as the industry’s weakest evaluated domain.
