The government built a vault around something that already left the building. Here’s the engineering proof.
This is Part 4 — the finale. Part 1 by Eric Mitchell: the political case. Part 2: the engineering case — the framework has no test suite. Part 3: the financial tell — why Altman’s offer is the survival math of a founder who knows the bubble knows it’s a bubble. This piece closes the series with the irony sitting under all of it: they may win every institutional fight and still lose, because the thing they’re trying to contain was never containable in the first place.
“The government built the most consequential gate in the history of American technology policy. It controls what models ship, to whom, on what timeline. It can trigger a global recall. It can restore partial access through a single letter. And it has no test suite.”
— Part 2 of this series. The gate has no criteria. This piece goes one level deeper: even with criteria, the gate can’t hold. Here’s why.
The Premise of Containment Has Already Failed
Part 3 ended with a question nobody in Washington will say plainly: what happens when the government wins the institutional fight — the off-switch, the equity stake, the regulatory framework — and the thing it was fighting to contain has already left the room?
That’s not a hypothetical. It’s the current state of the technology.
The government’s model of AI containment assumes that capability lives in a controlled artifact — a specific model, deployed by a specific company, accessible through a specific API — and that controlling access to that artifact controls the capability. Recall the model, control the capability. Gate the deployment, control the capability. Take a stake in the company, align the incentives.
Every piece of this framework is wrong. Not wrong in implementation — wrong in premise. Capability in frontier AI doesn’t live in a controlled artifact. It propagates through the ecosystem through a mechanism the government’s own researchers have documented in precise detail, and which no proposed regulatory measure fully addresses. The mechanism is called distillation. And it means the vault was empty before the lock was installed.
What Distillation Actually Does
Distillation is how you take capability from a large, expensive model and transfer it to a smaller, cheaper one — not by copying the weights, but by using the large model’s outputs to train the smaller model. You prompt the capable model, collect its responses, and use those responses as training data. The student model learns to imitate the teacher’s behavior without ever touching the teacher’s weights. [8].
This is how most of the open-source AI ecosystem develops. It’s how Meta’s Llama models have been refined, how DeepSeek built competitive reasoning capability at a fraction of U.S. compute costs, and how virtually every efficient frontier-competitive model in 2026 was developed.[10;13].
It’s also, as the Center for a New American Security documented in a major policy report this year, how China’s AI ecosystem has been systematically extracting capability from U.S. frontier models at industrial scale.
Here is the part that breaks the containment premise:
Distillation doesn’t require access to the weights. It requires access to the outputs.
Anthropic, Google, and OpenAI have documented that named Chinese entities — DeepSeek, Moonshot, MiniMax — together generated over 16 million exchanges with U.S. models, representing an estimated 150 to 400 billion tokens of extracted capability [5].
DeepSeek-R1’s entire supervised fine-tuning dataset is estimated at 6.4 billion tokens.
The adversarial campaigns extracted more capability than that model’s entire training dataset — not by stealing anything, but by asking questions through APIs that were openly available.
The government recalled Anthropic’s models and demanded zero jailbreaks before restoration. Meanwhile, the capability those models represent had been flowing out through commercial APIs for months, in a form that requires no jailbreak at all — just a subscription and a well-structured prompt.
The Front Door Was Always Open
The CNAS report on adversarial distillation describes the infrastructure in detail that should end any serious policy conversation about containment through model access restriction. The adversarial distillation supply chain runs through commercial token mixers — services like OpenRouter that aggregate access to multiple models through a single API endpoint.
It runs through “hydra cluster” architectures: distributed networks of fraudulent accounts where any single disabled account is immediately replaced by another. One proxy network operated more than 20,000 fraudulent accounts in parallel. When Anthropic released a new model during an active campaign, the Chinese entity conducting it pivoted within 24 hours, redirecting nearly half its traffic to capture capabilities from the latest version.
This is not hacking. It is not a cyberattack. It is a sophisticated use of commercially available services. The “vault” the government is building around frontier AI models is a vault whose contents are sold at the front counter.
The proposed Deterring American AI Model Theft Act unanimously cleared the House Foreign Affairs Committee in April 2026 + [5].
NSTM-4, issued by the White House’s own Office of Science and Technology Policy the same month, found that “foreign entities, principally based in China, are engaged in deliberate, industrial-scale campaigns to distill U.S. frontier AI systems.” [5] The government knows this is happening. It is building a gate that restricts access for American developers, researchers, and allied nations while doing essentially nothing to stop the adversarial extraction that motivated the framework in the first place.
The Fable 5 recall constrained more than 100 American institutions for fourteen days.
The Chinese distillation campaigns it was supposedly designed to address continued operating through token mixers the entire time. [6;15;11;10]
Weights Are Just Bits, and Bits Copy
There is a second, harder version of this problem that doesn’t require adversarial actors at all.
Model weights are files. They are very large files — the weights for a frontier-scale model can run to hundreds of gigabytes — but they are files. They can be copied, stored, transferred, and deployed by anyone with the hardware to run them. Once a capability is trained into a set of weights and those weights exist anywhere outside an air-gapped facility, containment is a matter of degree, not kind.
The open-weight frontier in 2026 makes this concrete. DeepSeek V4-Pro, with 1.6 trillion parameters and 49 billion active, is the largest open-weight model available — and it is publicly downloadable.
Llama 4, Qwen 3.6, and multiple other models with frontier-competitive reasoning capability are openly available and can be run locally, fine-tuned without restriction, and deployed without any API that a government could monitor or gate. [11]. The gap between open-weight and proprietary capability has closed to the point where leading technical analysts project open-weight models will match proprietary alternatives on the majority of practical tasks by late 2026.
A regulatory framework built on controlling access to specific proprietary models is a framework that becomes strategically irrelevant as open-weight alternatives reach parity. The government is building a gate in front of one door in a building with no walls.
What My Published Architecture Already Says About This
I want to be direct about the timeline, because it matters.
On April 2026 — seven weeks before the Fable 5 recall, two months before EO 14409 — I published a piece on this Substack arguing that the story of Mythos finding a 17-year-old FreeBSD exploit wasn’t about the vulnerability. It was about what the finding revealed: that capability in these systems emerges from training in ways that are not fully predictable, cannot be designed out, and cannot be removed after the fact without destroying the system’s usefulness.
