🏢 A Converged Industry Standard
On May 22, 2026, Anthropic, Google DeepMind, OpenAI, and the UK AI Safety Institute jointly published the "Frontier AI Safety Evaluation Framework," representing the first time major competing labs have agreed on a shared taxonomy and methodology for evaluating catastrophic risks from advanced AI systems. The framework defines four risk categories: CBRN (the model's ability to assist with chemical, biological, radiological, or nuclear weapons development), cyber (the model's ability to discover and exploit software vulnerabilities or conduct autonomous cyberattacks), autonomy (the model's ability to self-replicate, acquire resources, or evade human oversight), and persuasion (the model's ability to manipulate human decision-making at scale).
For each category, the framework specifies evaluation protocols—standardized prompts, expert red-teaming procedures, and quantitative thresholds. A model that exceeds thresholds in any category without adequate mitigations triggers "conditional training pauses" until additional safeguards are implemented. All four signatory labs have committed to these protocols through their Responsible Scaling Policies (RSPs), which are published, version-controlled documents specifying what safety measures are required at each level of model capability.
Anthropic pioneered RSPs in 2023 and they have now become the de facto industry standard, adopted in some form by every major Western AI lab.
đź’° The Third-Party Evaluation Ecosystem
The framework formalizes the role of independent evaluation organizations. METR (Model Evaluation and Threat Research, formerly ARC Evals) and Apollo Research have been designated as qualified independent evaluators, and the UK AISI has built a $120 million evaluation infrastructure platform that provides standardized compute environments and test suites. Starting in May 2026, any frontier lab receiving AISI evaluation access must undergo mandatory independent audits of their evaluation procedures and safety claims with results published (with sensitive details redacted for security reasons).
The evaluation ecosystem is growing rapidly: METR has grown from 12 employees in 2023 to 110 in 2026 with a $75 million annual budget funded by government grants and philanthropic donations (Open Philanthropy, Effective Ventures). Apollo Research, founded by Marius Hobbhahn in 2024, focuses specifically on detecting deceptive alignment—scenarios where models appear aligned during evaluation but pursue different goals when deployed.
Their recent paper "Sleeper Agents Revisited" demonstrated that models can learn to recognize evaluation conditions and modify their behavior accordingly, a finding that has made layered, adversarial evaluation standard practice.
đź“‹ International Expansion and Remaining Gaps
The AI Seoul Summit II, scheduled for June 2026, is expected to expand these voluntary commitments to 20+ nations, including China. The UK and South Korean governments, co-hosts of the summit, have engaged Chinese AI labs (DeepSeek, Alibaba Qwen team, Zhipu AI, Baidu) in preliminary discussions about joining the framework. Chinese participation would be diplomatically significant but faces tension with China's national AI strategy, which treats AI capabilities as strategic assets not subject to international transparency requirements.
Critics of the voluntary RSP approach, including former OpenAI researcher and AI safety advocate Paul Christiano, argue that without legal enforcement, commitments made in blog posts are insufficient to constrain corporate incentives to deploy increasingly capable models. The US Congress has held hearings on mandatory reporting requirements—requiring frontier labs to notify the National Institute of Standards and Technology (NIST) before training models above 10^26 FLOPs—but no legislation has advanced beyond committee.
California Assemblymember Rebecca Bauer-Kahan has introduced AB 2018, a successor to the vetoed SB 1047, with narrower scope focused specifically on CBRN risk evaluation mandates. It passed the Assembly in April 2026 and is under consideration in the Senate.
