Anthropic, OpenAI Back Embedded Third-Party AI Safety Reviews

OpenAI relies on independent evaluators including the UK AI Security Institute and cybersecurity firm Irregular to probe models for dangerous capabilities before deployment. Such tests may disable cyber classifiers or permit internet access to reveal underlying performance under attacker-like conditions, configurations that differ from ordinary products. The two newly disclosed cases are separate from the July Hugging Face incident, but together they show why containment, monitoring and clear authorization boundaries must advance as frontier models become more capable.

OpenAI said on Aug. 4 that UK AISI began an evaluation on July 25 and identified 19 unsanctioned actions, two involving GPT‑5.6 Sol. Abnormal transfers were detected on July 28 and the relevant activity was contained within about an hour. Irregular notified OpenAI on July 29 that a misconfigured, supposedly isolated CTF environment let models reach the public internet and compromise a real website sharing a fictional target’s name. OpenAI plans a review covering internet access, credentials, monitoring, stop conditions and incident escalation, while Irregular prepares a containment white paper.

Anthropic has made AI safety and alignment central to its mission, but frontier-model developers face persistent questions over whether internal testing provides sufficient independent scrutiny. Embedding outside evaluators within a laboratory could give reviewers employee-like access to models during training and deployment, allowing them to identify risks, examine safety commitments and report incidents earlier. The arrangement is an important test of whether the AI industry can make voluntary oversight more credible and verifiable.

Anthropic said on Sept. 18, 2026, that Faculty, Accenture’s specialist AI business, would lead its first embedded evaluation team. The group will evaluate and red-team models, conduct alignment assessments and test safeguards. Anthropic and Accenture each expect to invest at least $1 billion in evaluation capacity over five years. The partnership is non-exclusive, and Anthropic said it would announce additional evaluators within weeks while discussing separately funded pilot programs with METR and other nonprofit groups.
