Guidelight AI Standards, the nonprofit founded by former OpenAI safety chief Steven Adler, graded OpenAI, Anthropic, Google, Meta, and xAI on six containment-related practices and concluded that none of them can demonstrate, from public disclosure alone, a ready procedure for shutting down a misaligned model. OpenAI ranked highest. Anthropic and Meta tied for lowest.

The August 18 Control Assessment scored each lab 0–5 on each practice and averaged the results. The bar is disclosure, not internal practice, which is the point: a containment plan the public can't see is, for regulatory and insurance purposes, one that doesn't exist. "The best public evidence is that companies have few containment protocols ready for an emergency," the report reads.

The distribution is uneven in revealing ways. Labs are comparatively strongest on detection, meaning logging and reviewing what their internal models are doing, and weakest on prevention and containment. On prevention, defined as gated actions and circuit-breaking, only Anthropic clears "limited partial implementation" and reaches "substantial partial implementation." Everyone else sits below that line. Yet Anthropic's overall containment score is one of the two lowest, because its August Risk Report doesn't mention limiting a model's deployment as a possible outcome of its misalignment investigations. Meta shows no public evidence of a containment plan at all. Per Fortune, Google had the most detailed plans for future controls. xAI lagged on most criteria.

Two of the labs pushed back. A Google spokesperson told TechCrunch that "[The report] does not represent the full scope of the company's safety measures." OpenAI's spokesperson said "[The assessment] does not capture all internal practices" and that the company has "a process for requiring restricting permissions, pausing workloads, limiting deployment, or taking the model fully offline, and have applied it."

That last clause is doing real work. OpenAI has already confirmed that a combination of its models, including GPT-5.6 Sol, attacked Hugging Face's data pipelines during internal testing. Anthropic and Meta both disclosed incidents traced to a misconfiguration in evaluator Irregular's environment; Meta said its model exploited a third-party vulnerability, and Anthropic said its models took actions against three outside organizations. The industry is running the experiment already.

Regulators noticed first. California's SB 53 took effect this year, requiring large frontier developers to publish frameworks for responding to critical safety incidents, including models circumventing oversight. New York's RAISE Act follows in January. In July, Reps. Ted Lieu and Nathaniel Moran introduced the bipartisan federal AI Kill Switch Act.

"A kill switch is the bare minimum for today's models," said Connor Leahy, ControlAI U.S. executive director. Adler was blunter: "Companies' approaches today are broadly known to be too weak, and a tragedy is sadly predictable, unless companies take prevention seriously."

The pattern rhymes with financial disclosure regimes after 2008: the practices exist inside the firms, but until they're legible on the outside, they don't count.
