Overview
FLI works to reduce large-scale risks from transformative technologies, with a particular focus on advanced AI, nuclear weapons, biotechnology, and climate. In the AI space, it funds technical safety research, runs policy advocacy, and convenes the annual Future of Life Award.
Activities
"Pause Giant AI Experiments" open letter
In March 2023 FLI published the open letter calling for a six-month pause on training AI systems more powerful than GPT-4. It was signed by more than 30,000 people, including Yoshua Bengio, Stuart Russell, Elon Musk, Steve Wozniak, and Yuval Noah Harari. No signatories came from the leadership of OpenAI, Anthropic, or Google DeepMind, a contrast with the later CAIS statement of May 2023.
The letter called for a pause on frontier training; joint safety protocols with independent audits; and government action on AI regulatory authorities, compute oversight, provenance and watermarking, liability, and public safety research and development. FLI followed with a "Policymaking in the Pause" companion document on April 12, 2023, translating the letter into concrete recommendations.
EU AI Act advocacy
FLI's Brussels office was active in the drafting and passage of the EU AI Act (Regulation 2024/1689), particularly the general-purpose AI (GPAI) and systemic-risk provisions.
AI safety summit participation
FLI affiliates participated in the UK AI Safety Summit at Bletchley Park in November 2023, which produced the The Bletchley Declaration (AI Safety Summit, 1–2 November 2023).
AI Safety Index
FLI publishes a recurring AI Safety Index grading major AI developers on their safety practices. The summer 2026 edition, released July 7, 2026, graded nine AI developers across six domains: Anthropic highest at C+ (a numeric score of 2.66), OpenAI and Google DeepMind at C, Meta at D+, and xAI at F, with the report cautioning that frontier leaders had backslid on safety over the preceding six months (Source: insideaipolicy.com). No developer scored above C+; xAI (0.65), DeepSeek (0.47), and Mistral (0.33, last place) received failing marks, and the expert panel found that labs have weakened prior commitments to pause development unilaterally (Source: dcthemedian.substack.com). The full index — 37 indicators across six domains, with an evidence cutoff of June 3, 2026, plus a Chinese Regulatory Context annex — is summarized at FLI AI Safety Index — Summer 2026 Edition (Future of Life Institute, July 2026). Its reviewers additionally flagged the industry's pivot to military AI use as an emerging current-harm risk, and found Existential Safety the weakest domain industry-wide, with no company exceeding C-.
Position in the AI safety ecosystem
FLI is positioned as more prescriptive than CAIS but less confrontational than the grassroots PauseAI movement. Its long-standing relationships with academic AI safety funders, including Open Philanthropy and the Survival and Flourishing Fund, have made it a major distributor of safety research grants.
