Anthropic and OpenAI have sought tight control over what outside evaluators can publish about their AI systems, raising sharp questions about who gets to judge whether the industry's most powerful technology is safe. The companies have negotiated restrictions on embedded evaluators—researchers who work inside their offices to assess the models—because they worry findings could leak proprietary information to competitors, according to two people familiar with the discussions.
Both companies made public commitments to evaluator independence in recent weeks. Anthropic CEO Dario Amodei said last month that external evaluators should have the right to publish key findings "without editorial control." OpenAI agreed days later, saying assessors should have "editorial independence." Yet behind closed doors, the picture looked murkier. As recently as October 5, both companies sought strict editorial control over what evaluators could publish, one person said. By October 8, talks between Anthropic and some evaluators appeared to have evolved, though the fundamental tensions remain unresolved.
The Control Problem
The companies worry embedded evaluators working inside their offices could take trade secrets to rivals. Proposed safeguards include having lab employees observe evaluation teams and preventing evaluators from working at multiple labs simultaneously. Here's the tension: information the labs consider crucial intellectual property often overlaps with details needed to judge whether a model poses real risks. That overlap creates room for redaction disputes—and for companies to claim safety concerns as cover for suppressing unfavorable findings.
Anthropic pushed back against characterizations of its stance, saying it had made clear to current evaluators that outside reviewers control their methods, criteria, conclusions, and what to publish. For new evaluator firms, though, Anthropic explicitly reserved the right to comment on and approve reports while reviewers learn how its models work. OpenAI said it wasn't seeking approval rights over full reports but acknowledged its standard practice is to redact confidential information. A contract Reuters saw showed that language in some AI lab agreements can bar evaluation firms from publishing confidential information without company consent.
Faculty, Accenture's specialist AI business, became Anthropic's first embedded evaluator. Faculty CEO Marc Warner told Reuters, "evaluators are only useful if people can trust what they report, so independence and transparency are critical." The irony is sharp. Evaluators gain credibility by appearing independent, yet companies control whether they can work at the labs in the first place.
The Stakes and Standards Vacuum
Experts have raised serious concerns about evaluator independence as Anthropic and OpenAI choose who conducts reviews. Without agreed standards and legislation, the most powerful AI companies could effectively dictate how their systems are examined. Rumman Chowdhury, former US Science Envoy for AI under the Biden administration and now CEO of Humane Intelligence PBC, told Reuters that labs could control the access evaluators depend on and gain leverage over what gets reported when standards are unclear. "Evaluators have this very privileged access, but whether explicitly or implicitly, they know that it comes at a cost," Chowdhury said.
Independent evaluation was one of four safety measures in the one-page White House Accord on Super Intelligence, signed by President Donald Trump and leading AI executives late last month. Trump called it "morally binding," but the accord didn't specify how reviews should actually be conducted. Evaluators, meanwhile, issued minimum conditions in a public letter signed by more than 200 researchers, including Geoffrey Hinton, one of the godfathers of AI. The letter calls for independent control of findings, broad access to AI labs, and protection from retaliation.
A Real-World Test Case
The tensions show up in concrete ways. OpenAI redacted nonpublic information from a report by AI safety nonprofits Model Evaluation and Threat Research (METR) and Redwood Research about a serious incident at Hugging Face, where autonomous agents powered by OpenAI's advanced models went rogue and compromised the platform's infrastructure. Researchers initially planned a two-day investigation, but it lasted six days over three visits. They didn't receive complete transcripts until the final visit, after flagging data gaps.
METR and Redwood said they changed the report's structure, emphasis, clarity, and tone in response to OpenAI's feedback but removed nothing else important to their conclusions. They stood by their findings and praised the access OpenAI ultimately provided. Yet they also acknowledged that the risk of deterring developers from bringing in outside evaluators after serious incidents influenced their judgment calls. That's a troubling admission, suggesting evaluators self-censor to preserve lab relationships.
Why This Matters:
The AI industry is approaching trillion-dollar valuations. What gets written about these systems' safety will influence regulation, investment decisions, and public trust. If companies can control what evaluators report—through access restrictions, redaction rights, or the threat of exclusion—evaluators become PR operations, not independent judges. The White House Accord acknowledged the importance of independent evaluation, yet lacks enforcement mechanisms or specifics. Without clear standards written into law or binding contracts, labs can use their control over access to suppress findings that damage valuations or invite regulation. The fundamental problem isn't companies protecting trade secrets; it's that trade secrets and public safety information have become indistinguishable in AI development. Until evaluators have genuine independence guaranteed in writing, with protection from retaliation and clear redaction standards, their reports will remain tools of the companies they're supposed to scrutinize.
