Regulating the AI Frontier through Export Controls

AI is advancing at an unprecedented pace, generating excitement about its transformative potential while raising critical concerns about the risks to national security and misuse by malicious actors. Amid these rapid developments, the BIS, on January 13, 2025, issued a landmark export control framework - the AI Diffusion Rule.

Designed to restrict adversarial access to America’s most advanced AI technologies—including frontier-level models and the high-performance computing integrated circuits (ICs) essential for their training—the rule’s evolution under the Trump administration bears watching, given its potential impact on AI development, geopolitics, and industry dynamics. Below is an overview of the rule’s background, key provisions, and practical steps stakeholders can take to prepare for compliance.

Technical and Geopolitical Background

Computing advances have long relied on Moore's Law—the doubling of transistor density every two years—but rising costs and physical constraints have shifted the focus to specialized AI chips. This has led to the development of specialized AI chips, such as GPUs, ASICs, and FPGAs, which now drive innovation.

Specialized Chips in AI

1. GPUs (Graphics Processing Units): Originally designed for graphics, GPUs excel at parallel processing and are indispensable for training large AI models like language models.

2. ASICs (Application-Specific Integrated Circuits): Optimized for specific AI algorithms, they offer significant efficiency but are less flexible when adapting to new models.

3. FPGAs (Field-Programmable Gate Arrays): FPGAs can be reprogrammed post-manufacturing, allowing for flexibility. They are ideal for scenarios requiring customization, such as communication equipment and image processing, but are less efficient for tasks with strict energy limitations.

Global Supply Chain Dynamics

The U.S. leads AI chip design, while Taiwan’s TSMC dominates advanced semiconductor fabrication. Meanwhile, China faces challenges with high-end lithography, limiting its ability to produce cutting-edge hardware. Modern AI relies on specialized semiconductor hardware—optimized for parallel processing and matrix operations—to power large-scale training and inference. By leveraging these capacity constraints, the long arm reach of U.S. export laws, and critical choke points—particularly advanced lithography and design technologies—the AI Diffusion Rule restricts adversaries’ access to frontier AI and helps preserve a U.S. leadership edge.

Policy Objectives and Strategic Imperatives

On January 13, 2025, the Biden Administration introduced the AI Diffusion Rule, an export control framework aimed at controlling the flow of emerging AI capabilities. The rule targets two areas:

• Advanced computing ICs (GPUs and ASICs) critical for training and deploying large-scale AI models.

• Frontier AI model weights, defined as those trained using 10^26 or more computational operations.

The regulation took immediate effect with a 120-day compliance period for industry feedback. Its three primary goals are to:

1. Prevent Unauthorized Access: Restrict advanced AI technologies from reaching adversaries or high-risk entities to ensure that they are not exploited by foreign adversities.

2. Facilitate Responsible Use: Enable trusted foreign partners to access advanced AI capabilities under stringent controls to foster secure and collaborative international innovation. The rule introduces a tiered export framework, with countries designated under the Artificial Intelligence Authorization (AIA) group receiving differentiated treatment.

3. Reinforce U.S. Leadership: Establish export guidelines that protect national interests while maintaining America’s dominance in AI innovation.

Together, these objectives reflect the U.S.’s focus on managing transformative technologies in the AI ecosystem to maintain its geopolitical and technological edge.

Tiered Export Controls: Who Gets what?

A cornerstone of the AI Diffusion Rule is a multi-tiered export framework designed to incentivize global businesses to adopt U.S. standards and support AI development in allied nations.

Group One (Trusted Allies)

• Included Nations: The U.S. and 18 trusted allies, such as Japan, Canada, and the Netherlands.

• Access: Broad access to advanced AI technologies, contingent on compliance with certain comprehensive security standards.

Group Two (Intermediate Nations)

• Included Nations: Most nations (e.g., Israel, Turkey, and Singapore).

• Access: Default cap of 50,000 GPUs, with potential increases to 100,000 GPUs through memorandums of understanding (MOUs) that commit to decoupling from adversarial AI ecosystems, such as in China.

· Group Three (Adversaries)

• Included Nations: Adversarial nations, including China, Russia, and Iran.

• Access: Complete ban on U.S. AI technologies, with license requests presumed denied.

Smaller stakeholders, such as universities and startups, benefit from a low-volume exception allowing up to 1,700 GPUs per transaction without extended licensing reviews. Additionally, the rule closes the cloud rental loophole, preventing adversaries from bypassing restrictions through leased GPU clusters.

Three-Pronged Regulatory Framework – Chips, Model Weights, and Data Centers

The rule adopts a three-pronged strategy to regulate critical AI technologies:

1. Chip Regulation: This prong regulates high-performance computing hardware (certain GPUs and ASICs models), which are essential for advanced AI systems. Key measures include:

   1. Licensing Requirements: Exports, repexports, and in-country transfers of these chips require BIS approval.

   2. Low-Risk Transactions: New conditional license exceptions, such as TPP thresholds and ACM for manufacturing, are available to minimize disruptions to legitimate industries.

   3. Enhanced Scrutiny: Large-scale exports, particularly to high-risk regions, are subject to rigorous review.

   4. Global Allocation Framework: Advanced AI chips are now subject to a per-country allocation cap (e.g., 790 million total processing performance for certain Group 3 countries) aimed at ensuring equitable distribution while limiting overconcentration in sensitive areas.

2. Model Weight Controls: This prong focuses on proprietary AI models trained with 10 ^26 or more computational operations, now classified under a new export control classification (ECCN 4E091). Key aspects include:

   1. Licensing: Required for transferring top-tier model weights to most foreign destinations due to concerns over misuse in military or surveillance contexts.

   2. Exemptions: Open-source and lower-tier models remain largely unrestricted, preserving opportunities for academic and commercial research.

   3. A Foreign Direct Product Rule (FDPR): Extends U.S. jurisdiction over foreign-produced weights reliant on U.S. technology.

3. Data Center Standards: Establishes security requirements for facilities hosting advanced AI chips or model weights, including:

   1. Safeguards: Physical access controls, network monitoring, and encryption protocols.

   2. Incentives: Certification processes favor data center development within the U.S. or allied nations.

   3. Diversion Prevention: Strengthened end-use checks prevent unauthorized entities from accessing sensitive technologies.

Validation End User Programs

Another key component of the AI Diffusion Rule is the Validated End User (VEU) framework, which allows entities to exceed default export caps by meeting strict security standards. The program is divided into two categories:

1. Universal VEU (UVEU)

   1. For companies based in Group One countries (e.g., Microsoft).

   2. Permits global data center construction (excluding Group Three nations) if security protocols are upheld.

   3. Requires at least half of all computing resources to remain in the U.S., with no more than 7% in any single Group Two country.

2. National VEU (NVEU)

   1. For companies in Group Two nations meeting rigorous security requirements.

   2. Allows large-scale data center development within their home nation.

Both programs require compliance with U.S. cybersecurity frameworks such as FEDRAMP, NSA, and CISA. Companies meeting these criteria can bypass standard country caps, gaining significant business advantages for large-scale data center deployments. By offering a flexible security framework, the VEU programs attempts to incentivize global adoption of U.S.-aligned AI standards. For example, countries like the UAE have agreed to decouple from adversarial AI ecosystems to gain access to top-tier American technologies.

Strategic Implications and Next Steps

The AI Diffusion Rule marks a pivotal shift in U.S. export control policy, creating a more secure environment for advanced AI development. By expanding controls across the computing supply chain—such as high-performance chips, frontier AI model weights, and data center security—BIS intends to reduce adversarial access risks while encouraging trusted global collaboration. Although the incoming Trump administration’s exact stance is uncertain, the rule’s alignment with tougher China and broader trade-protection themes indicates it will likely remain in place.

Given these complex regulations, businesses may need to update compliance processes for all items (including foreign-made products) and bolster due diligence to meet evolving standards. Specifically, companies that suspect their products, services, or operations fall under the rule should.

• Assess potential impacts on cross-border chip transactions, data center projects, or AI model transfers.

• Evaluate the strategic benefits of UVEU or NVEU status.

• Develop robust compliance processes around allocations, closed AI model weights, and cybersecurity.

Early, proactive planning is important for mitigating risks and capitalizing on opportunities in a rapidly evolving AI landscape.
