Signal Future of Life Institute releases 2026 AI Safety Index

Summary

The Future of Life Institute published its Summer 2026 AI Safety Index on July 7, 2026, evaluating nine leading AI companies across 37 indicators in six domains, with grades assigned by an independent panel of seven AI researchers and governance experts. Anthropic took the top overall grade of C+ (2.66 of 4.0), followed by OpenAI at C (2.28) and Google DeepMind at C (2.01), while Meta scored D+ (1.32) and Z.ai and Alibaba Cloud scored D- (0.88 and 0.87); xAI (0.65), DeepSeek (0.47) and Mistral (0.33) received failing grades. No company scored better than C- on existential safety, with Anthropic's D+ the best in that domain, and the report found that Anthropic, OpenAI, Google DeepMind and Meta had all weakened or voided earlier commitments to pause development if risk thresholds were approached. The same companies, which had previously banned military applications, have gradually reversed course between 2024 and 2026, joining xAI and Mistral in seeking defense partnerships. Coverage noted the background that the EU AI Act's GPAI systemic-risk obligations are scheduled to take effect on August 2, 2026.
