The Grade Sheet Nobody Wanted
The Future of Life Institute published its Summer 2026 AI Safety Index on July 7, 2026. Nine frontier AI companies were evaluated by a panel of seven independent researchers from UC Berkeley, the University of Montreal, and the University of Wisconsin-Madison, using a 37-indicator framework across six domains.
The findings are a structured form of bad news. No company received an A grade in any single category. The highest overall score in the industry — Anthropic’s 2.66 on a 4.0 scale — translates to a C+.
Here is the full leaderboard.
The Scores
| Lab | Score | Grade |
|---|---|---|
| Anthropic | 2.66 | C+ |
| OpenAI | 2.28 | C |
| Google DeepMind | 2.01 | C |
| Meta | 1.32 | D+ |
| Z.ai | 0.88 | D− |
| Alibaba Cloud | 0.87 | D− |
| xAI | 0.65 | F |
| DeepSeek | 0.47 | F |
| Mistral | 0.33 | F |

What the Six Domains Measured
The index evaluated each lab across six categories, scored separately and averaged into the final GPA:
- Risk Assessment — whether labs formally identify and quantify the hazards their models could cause
- Current Harms — concrete harms from deployed products: bias, misuse, dangerous outputs
- Safety Frameworks — stated policies: deployment criteria, capability thresholds, red lines
- Existential Safety — technical work on alignment, interpretability, and catastrophic-risk prevention
- Governance & Accountability — board structures, auditing, external accountability
- Information Sharing — transparency about capabilities, limitations, and safety research
Anthropic leads five of the six domains. OpenAI leads Risk Assessment. Existential Safety was the weakest category across the entire industry, with Anthropic’s D+ being the best score any lab achieved in that domain.
The Headline Finding: Military AI Reversals
The report’s most pointed finding isn’t a company-specific grade — it is a pattern across the top four. Between 2024 and 2026, Anthropic, OpenAI, Google DeepMind, and Meta all reversed prior restrictions on military applications and began actively pursuing defense contracts — joining xAI and Mistral, which had already been pursuing such work.
Stuart Russell, an expert reviewer on the panel, noted: “The capabilities race has become more extreme. Companies backed away from earlier commitments to release systems with appropriate safety measures.”
Reviewer David Krueger added: “AI companies’ lack of credible safety plans is scandalous. CEOs’ gestures toward pausing lack transparency on how unprepared they are.”
The reviewers flagged military AI as an “emerging current harm risk” and cited it explicitly in the Current Harms domain scoring.
Anthropic: Leads Everything, But Dropped a Key Pledge
Anthropic earns the highest overall grade and leads all six domains or comes close in each. Its relative strengths are in Information Sharing (B+), Governance & Accountability (B), and Safety Frameworks (B−). These reflect published model cards, Claude’s Constitution, the Responsible Scaling Policy (RSP), and greater-than-average external transparency.
However, the index identifies a specific retreat: in February 2026, Anthropic dropped its pledge to never train a system unless it could guarantee in advance that its safety measures were adequate. The reviewers treat this as a meaningful weakening of the RSP framework, not a minor rewording.
The C+ ceiling on the industry’s best performer communicates something worth internalizing: even the most safety-conscious frontier lab is operating far below what the researchers consider adequate.
xAI: The Sharpest Decline
The most dramatic change from the prior index is xAI’s drop from 4th place to 7th, and from a passing-range grade to a failing F at 0.65. The company had previously sat in the C+/D range in 2025 evaluations.
The index does not provide a single-sentence causal explanation for the fall. The pattern across the six domains points to a combination of weak safety documentation, an absence of formal risk assessment processes, and the military AI posture that was already a feature of xAI before most other labs reversed course.
xAI’s Grok model series has expanded rapidly through 2026 — Grok 4 and subsequent versions — but lab-level safety commitments have not kept pace with capability deployment. Reviewers noted “corporate safety frameworks often lack quantitative risk thresholds and independent audits.”
Meta: The Notable Improvement
Meta climbed from 6th to 4th place, improving its grade from D to D+. At 1.32 overall, it still sits well below the passing threshold, but the direction is positive. The improvement reflects Meta’s increased publication of safety research related to its open-weight Llama model series and marginal governance improvements.
Meta’s approach — open-weight models with limited lab-level deployment control — creates structural challenges for safety scoring that the index doesn’t fully resolve. Publishing a model doesn’t give a lab the ability to audit downstream use, and the framework’s Governance & Accountability domain implicitly rewards centralized deployment structures.
The Three Failing Labs
Three companies receive failing grades (F), spanning three regions:
xAI (US, 0.65): Drops from mid-tier to failing. Heavy focus on deployment speed and capability demonstration; limited public safety documentation.
DeepSeek (China, 0.47): Consistently low on transparency and governance. Open-weight models released with minimal safety documentation.
Mistral (France, 0.33): Lowest score in the index. The European lab has publicly positioned against safety restrictions and in favor of minimal oversight, which scores poorly across nearly every domain the FLI evaluates.
The geographic spread — one from the US, one from China, one from Europe — undercuts any narrative that safety failures are regional. The report states explicitly that “the problem is global.”
What the Index Is and Isn’t
The FLI Safety Index grades organizational policies and public commitments, not deployed product performance. A company can score well on Governance & Accountability while shipping a model that causes harm at the product level — and vice versa.
The data collection cutoff was June 3, 2026. The assessment is based on public materials (model cards, research papers, published policies) plus a targeted survey sent to each company. Not all companies responded to the survey.
This means the index is best read as a measure of stated commitments and documented processes — what labs say they do, what they’ve published, what structures they claim to have. Whether those commitments hold under competitive pressure is a different question, and the military AI reversal finding suggests the gap between rhetoric and practice is widening, not narrowing.
