Frontier AI would face a federal safety test before release

5 min readLast updated June 14, 2026

Why it matters

The most powerful AI models would have to pass government testing at the Department of Energy before they could ship, and companies that skip it would face fines of at least $1,000,000 a day. The bill even tells the government to study nationalizing AI if a system starts looking like superintelligence.

S. 2938, the Artificial Intelligence Risk Evaluation Act of 2025, puts the Department of Energy in charge of stress-testing the most powerful AI systems before they reach the public. The Secretary of Energy would have 90 days after the bill becomes law to stand up an Advanced Artificial Intelligence Evaluation Program.

The program only targets the frontier. The bill defines a covered "advanced" system as one trained with more than 10^26 computing operations — a threshold aimed at the largest models, not everyday apps or smaller open models. The Secretary could later propose a new threshold, but it can't take effect unless Congress passes a joint resolution approving it.

S. 2938 Bill Summary

What S. 2938 actually does.

1

No release until your model passes federal testing

A covered developer can't deploy an advanced AI system in interstate or foreign commerce until it complies with the program. "Deploy" includes selling, providing access, or releasing the system open-source.

2

$1,000,000-a-day fine for skipping the program

A developer that refuses to participate, or deploys a covered system without complying, faces a fine of not less than $1,000,000 for each day the violation continues.

3

Only frontier models are covered

The rules apply to systems trained with more than 10^26 computing operations, a threshold set at the largest models. The Secretary could propose a different threshold, but it takes effect only if Congress approves it by joint resolution.

4

Developers hand over code, weights, and training data

On request, covered developers must give the Department of Energy the underlying code, training data, model weights, interface engine, and detailed architecture information for the system.

5

The program studies superintelligence — and how to contain it

The program must assess whether a system could reach artificial superintelligence, develop containment and mitigation protocols, and propose oversight options for extreme cases, including potential nationalization.

6

DOE stands it up in 90 days, reports to Congress in 360

The Secretary of Energy must establish the program within 90 days of enactment and send Congress a permanent oversight framework within 360 days, updated at least once a year. The program ends after 7 years unless Congress renews it.

Who benefits from S. 2938?

National security agencies

They would get a formal federal program for testing the most powerful AI against risks the bill names directly — weaponization by foreign adversaries or terrorist organizations, threats to critical infrastructure, and loss-of-control scenarios.

Workers worried about AI disruption

The bill counts significant erosion of labor markets and economic competition as an "adverse AI incident," which means the program has to evaluate those harms, not just safety failures.

Civil liberties advocates

Significant erosion of civil liberties is listed as a reportable risk, so it has to be tested for, planned around, and reported to Congress.

Congress

Lawmakers would receive a detailed oversight framework within 360 days and at least yearly updates for the life of the program, giving them a steady stream of empirical data on frontier AI for up to 7 years.

Who is affected by S. 2938?

Frontier AI developers

Companies that design, code, produce, own, or substantially modify a system above the 10^26-compute threshold would have to enroll in the program and turn over their code, weights, and training data on request.

Open-source AI publishers

The bill defines "deploy" to include open-source release, so publishing a covered model openly would trigger the same compliance rules as selling it.

Compute and cloud providers

The required framework plan must propose continuous monitoring of AI hardware usage and cloud-computing deployments, signaling future scrutiny for the companies that supply the infrastructure.

Developers of highly autonomous systems

Projects pushing toward systems that can act autonomously, match human cognition across most tasks, or self-modify would draw the closest attention, since the program is built to assess exactly those capabilities.

S. 2938 — Full Bill Text (GovInfo)

The official government publishing record for the introduced text of the bill, in PDF, text, and XML formats.

Department of Energy — Artificial Intelligence

The bill puts the Department of Energy in charge of testing frontier AI; this is DOE's hub for its AI work, including responsible-AI and adversarial testing.

DOE Artificial Intelligence Strategy

DOE's published AI strategy, the framework the agency would build on to stand up the Advanced Artificial Intelligence Evaluation Program.

42 U.S.C. 5195c — Critical Infrastructures Protection Act of 2001

The bill's 'adverse AI incident' definition borrows its meaning of critical infrastructure from this statute.

8 U.S.C. 1189 — Designation of Foreign Terrorist Organizations

The bill defines 'foreign terrorist organization' by reference to this statute, which authorizes the Secretary of State to make such designations.

S. 2938 Common Questions

What AI models would S. 2938 actually cover?

Only the largest. S. 2938 covers "advanced" systems trained with more than 10^26 computing operations — a threshold aimed at frontier models, not everyday apps or smaller open models. The Secretary of Energy could propose a new threshold, but Congress has to approve it.

Could the government block an AI model from launching?

Yes. Under S. 2938, no one can deploy a covered advanced AI system in interstate or foreign commerce until they've complied with the testing program. That covers selling it, giving API access, or releasing it open-source.

How big is the fine for skipping the program?

S. 2938 sets the penalty at not less than $1,000,000 for each day a developer is in violation — either refusing to participate or deploying a covered model without complying.

Does S. 2938 apply to open-source AI?

Yes. The bill defines "deploy" to include releasing a model open-source, so publishing a covered advanced AI system openly triggers the same compliance rules as selling it.

What would AI developers have to hand over to the Department of Energy?

On request, covered developers must provide their underlying code, the data used to train the model, the model weights, the interface engine, and detailed information about the training and architecture.

Does S. 2938 really let the government consider nationalizing AI?

Yes. The bill directs the Department of Energy to develop oversight options for extreme cases — including potential nationalization — if a system seems likely to reach artificial superintelligence.

What counts as an "adverse AI incident"?

S. 2938 defines it as loss-of-control scenarios, weaponization by foreign adversaries or terrorist groups, threats to critical infrastructure, erosion of civil liberties or labor markets, or "scheming behavior" — a model deceiving its operators or hiding what it can do.

When would the program start, and does it expire?

The Department of Energy would have 90 days after enactment to launch the program and 360 days to send Congress a permanent oversight framework, updated yearly. The whole program sunsets 7 years after enactment unless Congress renews it.
