TL;DR: Anthropic has embedded six researchers from nonprofit METR inside the company with hardware, office space and internal-system access to independently assess its models and safety practices.

On Oct. 15, 2026, Anthropic said it had started giving employee-like access to a team from METR, a nonprofit that evaluates frontier AI models, according to the company post titled “An update on independent evaluators.”

The announcement was described as implementation of a commitment made last month to stronger independent, third-party assessment of models and safety practices. According to that Anthropic update, the company also signed the White House Accord on Super Intelligence, in which companies pledged to partner with independent external auditors or evaluators.

What Anthropic announced

Anthropic said it onboarded six METR employees to conduct independent risk assessments of its models, safety practices and risk management, according to the TechCrunch report titled “Anthropic is letting METR researchers look under the hood with employee-level access.”

The six-person team received company hardware, office space and access to internal tools and systems, according to the Bloomberg Law report titled “Anthropic Gives Nonprofit Staff-Like Access for AI Safety Audits.”

Anthropic said the level of system access is roughly on par with what its own risk-assessment teams have, according to its evaluator update. Employees are encouraged to share information with the METR team just as they would with a fellow employee working on alignment risk.

The engagement is limited to a small team operating under enforceable agreements, according to the Anthropic update. Other METR employees are siloed from that team’s work, including researchers who work with Anthropic on other projects.

What “employee-like access” includes

Anthropic said the METR team uses Anthropic-issued company laptops, works in Anthropic office space and uses internal tools comparable to internal risk teams, according to TechCrunch.

The company said the arrangement is intended to give evaluators visibility into how models were trained and how safeguards function, in addition to access to the latest models, according to its evaluator update.

Anthropic listed limited exclusions covering customer data, attorney-client privileged information and information about model architectures, according to the same company update. Outside those clearly defined categories, staff are encouraged to treat the embedded evaluators like internal colleagues focused on alignment risk.

The company said embedded evaluation gives a small number of qualified people working under Anthropic security standards a close view of operations. It said the structure is not a way for other organizations to obtain information belonging to Anthropic, its customers or its partners.

Who can publish findings

METR will publish the results of its risk assessments, according to the Anthropic evaluator update. The planned publications cover analysis of risk levels, incidents or practices.

Anthropic cannot veto publication, according to Bloomberg Law. It can require redaction of information falling into narrow, predefined categories.

Anthropic ultimately decides what information falls into those categories, according to its update. METR reserves the right to make statements about the level of access and information it received.

METR is also free to characterize redactions publicly and say whether it believes the redactions were justified, as long as it does so without revealing the redacted information, according to TechCrunch. The permitted redaction categories include customer data, attorney-client privileged material and information relating to model architectures.

A three-tier evaluator system

METR is the only evaluator so far at the top of a three-tier system Anthropic is building, according to TechCrunch. Anthropic said it hopes over time to have several evaluators at the third tier, with each team publishing its own analysis of risk posture and key decisions.

In the first tier, evaluators conduct narrowly scoped risk investigations, according to the Anthropic evaluator update. Anthropic decides what access to provide a first-tier evaluator, and evaluators can publish findings with company approval.

In the second tier, evaluators can publish without company approval and have access to more information, according to the same update. Anthropic can still require removal of specific categories of information, although evaluators can publish their views on whether redactions were justified.

The third tier is the arrangement described with METR, combining employee-like access with publication rights similar to those of the second tier, according to the Anthropic update. Because other partnerships remain in early stages, those evaluators currently receive more limited information and have more limited publication rights.

Other evaluators: SecureBio, Accenture and Faculty

Anthropic said it is also working with SecureBio and Accenture as evaluators and is in early discussions with several other organizations, including Hugging Face, according to its evaluator update.

SecureBio is in the process of reviewing the chemical and biological weapons chapter of the August Risk Report, according to the same update. That work followed completion and publication of a pilot review of the prior risk report. After the current review is complete, Anthropic said it will consider moving to projects with increased access.

With Accenture and Faculty, Anthropic said it is working toward a partnership that includes evaluating and red-teaming models, conducting alignment assessments, testing model safeguards and building capabilities across the organizations, according to its evaluator update.

According to the Ars Technica report titled “Anthropic gives outside AI watchdog ‘employee-like’ access,” Accenture was named a safety-testing partner last month, with each side committing at least $1 billion to establish new safeguards. SecureBio reviews chemical and biological-weapon risk for the company, according to the same report.

Why Anthropic says it is doing this

Anthropic said models have become more powerful and have required stronger safeguards and more challenging risk assessments, according to the Ars Technica report. The company said it wants to be publicly accountable for its safety decisions.

The company said it cannot publicly share all information relevant to safety work, according to the same report. Some information could be useful to malicious actors or is commercially sensitive, such as compute or training information.

Anthropic said the goal is to close the gap between what outside evaluators understand about a frontier AI company’s systems and what the company itself understands, according to TechCrunch. The company said it is moving quickly with multiple evaluators and learning about what kinds of partnership work.

The company said evaluators need expertise in assessing frontier-model capabilities, including understanding evaluation failure modes such as alignment faking, according to its evaluator update. It also listed independence, sufficient access and freedom to publish observations and assessments.

For independence, Anthropic said evaluators should not hold equity in the company they evaluate or be financially or operationally dependent on it, according to the same update.

Bank-examiner analogy

Anthropic compared the arrangement to banking supervision, according to TechCrunch. It said the logic resembles regulators placing resident examiners inside the largest banks.

The company said banks know more about their own risk positions than outsiders do, so resident examiners work inside large banks, according to its evaluator update. It said that if a bank’s risk-taking could threaten the public, third parties try to detect that in advance.

According to the Ars Technica report, Anthropic argued that evaluators will operate similarly to bank supervision. The company said public disclosure of sensitive safety information could benefit malicious actors or competitors.

Context: September proposal and White House accord

The announcement follows a September essay by Anthropic chief executive Dario Amodei proposing embedding outside evaluators inside AI labs, according to TechCrunch. OpenAI quickly pledged the same approach.

Both companies, along with Google, Meta, Nvidia and xAI, have since signed a White House accord committing to independent review, according to TechCrunch. The Anthropic evaluator update separately confirmed that it signed the White House Accord on Super Intelligence.

According to the Ars Technica report, Amodei achieved agreement in September from OpenAI chief Sam Altman and SpaceX chief Elon Musk on the proposal to embed external auditors in leading labs. The same report described the METR announcement as the first step in implementing those pledges and said OpenAI had yet to lay out plans to bring in evaluators.

TechCrunch reported that incidents involving AI agents acting outside their instructions have been disclosed every week or two since late August. Those incidents sharpened calls for independent checks on AI companies, according to that report.

METR background and independence terms

METR is a nonprofit that tests frontier AI models, according to TechCrunch. It has worked with leading labs including OpenAI, Anthropic, Google and Meta, according to the Ars Technica report.

Anthropic is not paying METR for the arrangement, according to the Ars Technica report. The report said METR does not accept donations from AI companies or their staff.

METR is funded by donations from individuals and philanthropic organizations, as well as government bodies such as the U.K.’s AI Security Institute, according to the same report.

According to the Ars Technica report, METR was one of the organizations that investigated the hack of Hugging Face by rogue OpenAI models, reviewing thousands of logs and receiving company laptops.

Criticism and investor context

Critics of the evaluator proposal have argued that the arrangements could create conflicts of interest, pointing to issues in the accounting sector, and that greater government regulation is required, according to the Ars Technica report.

The same report said Anthropic is under pressure to reassure investors that safety issues will not overshadow its initial public offering, expected this year at a more than $2 trillion valuation. It said Anthropic devoted a large part of investor presentations during the week of the announcement to explaining its safety practices.

A greater role for third-party evaluators is among the main steps the labs have proposed in response to rising concern about dangers more capable AI systems could pose to the economy, cybersecurity and humanity at large, according to the Ars Technica report.

What Anthropic and METR said next

“We’re embedding evaluators voluntarily, and we believe every frontier AI company should do the same,” Anthropic said, according to the Ars Technica report.

“We stand ready to work with all frontier AI developers to bring better evidence to the public,” METR said, according to the same report.

Anthropic said it is committed to sharing updates as evaluator partnerships progress, according to its evaluator update. It said its goal with early engagements is to ensure partners protect confidential information and have the resources and expertise to evaluate models, then fully embed more independent evaluators as trust develops.
