## **The file, the rack, and the rule**

*As AI models become more portable, the power to control their use can change hands. The important question is where it goes.*

On August 28, 2026, OpenAI notified SpaceX that it intended to wind down the agreement supplying OpenAI models to Cursor, with a proposed shutoff date of November 12\. Its explanation cited contractual compliance and a cancellation window triggered by Cursor's change of ownership. \[1\] The announcement describes a supplier exercising a contractual right over a product its customers had already incorporated into their work. The announced interruption arose from the business relationship; it did not require a deterioration in the model's capability. As proposals to slow frontier AI gather attention, contracts, model weights and computing infrastructure determine who can continue operating, and on whose terms.

Three places determine how that dependence operates: 

- *the file*, the model weights an operator can possess;
- *the rack*, the equipment and services required to run them;
- and *the rule*, the contractual and regulatory terms governing access and use.

Control can move between them without becoming less concentrated overall. An organization may gain possession of a model while remaining dependent on another party for capacity or permission. The relevant test is whether it can continue the required operation when that relationship changes.

On May 6, Anthropic had announced a different agreement, access to all the compute capacity at SpaceX's Colossus 1 data center. Its statement identified more than 300 megawatts and over 220,000 NVIDIA GPUs, with access expected within the month. \[2\] SpaceX was thus a compute supplier to Anthropic while also owning xAI, a competing model developer. The Colossus supply agreement, Cursor's acquisition and OpenAI's termination notice are separate arrangements. Their intersection shows how several forms of dependence can coexist between competitors.

*A company name is therefore an incomplete unit of analysis.* SpaceX's interest as a compute seller need not coincide with its interest as the owner of a model developer. Anthropic's relationship with a supplier need not determine its position on that supplier's competing product. The relevant questions concern the terms of each relationship, what one party provides, what the other must continue obtaining, and what either can withhold. Interconnection can support cooperation and competition simultaneously, while leaving the parties unequal in their ability to replace one another.

At the file, the relationship changes when the operator can possess the weights. They are the numerical parameters needed, alongside software and hardware, to run a model. DeepSeek's V4.1-Flash repository publishes weights under the MIT license and instructions for serving them. \[3\] Qwen3.8-27B publishes weights under Apache 2.0 with deployment instructions. \[4\]

An operator who possesses usable weights need not send every request to the originating laboratory. The laboratory's service can disappear without the local copy disappearing with it. License obligations and applicable law remain; possession does not create unrestricted rights. But cancelling an API account and stopping computation on someone else's machine are different operations.

This distinction crosses national boundaries. Thinking Machines Lab released Inkling on July 15, 2026, with downloadable weights and customization through its Tinker platform. Its model card specifies Apache 2.0\. \[5\] The US company, founded by former OpenAI CTO Mira Murati, provides a concrete instance of personnel continuity alongside a different distribution choice. Shared institutional ancestry does not require an identical commercial relationship with the user.

France's Mistral also distributes model weights, its Mistral Small 4 repository specifies Apache 2.0 and provides serving and fine-tuning instructions. \[6\] Nor does "open weights" describe one uniform arrangement. Moonshot distributes Kimi K3 under its own named license. \[7\] The repository and the license must be read together.

The commercial consequence is a change in who can become a supplier. A downloadable model can support multiple operators offering access to the same underlying weights. The original developer may still sell the best service, provide important updates or retain substantial influence. For a particular checkpoint that the license permits an operator to serve, and that the operator can actually run with the required software and hardware, continued access to the developer's service is no longer technically necessary. Responsibility for maintaining that deployment, however, passes to the operator or another supplier.

The relationship has changed, but the obligations have not disappeared. Someone must supply capacity, maintain the software and answer for failures. The practical value of possessing the weights depends on whether the organization can assume those obligations itself or obtain them from a replaceable provider.

At the rack, possession must be converted into a working service. Active parameters, stored weights and serving costs measure different requirements. [6](#) Published work on attention and memory caching addresses parts of that burden; actual cost depends on the complete deployment and its workload. \[3\]

The hardware supplying that infrastructure is changing too. On July 23, AMD and Cerebras announced a combined inference system: AMD GPUs would process prompts and context, while Cerebras wafer-scale hardware would generate output tokens. Initial availability was planned through Cerebras Cloud in the second half of 2026\. \[8\] The announcement describes a division of work between architectures; it does not establish independently measured operating costs or general availability. The proposed delivery through Cerebras Cloud makes the institutional distinction explicit. A customer could benefit from an alternative hardware architecture while continuing to purchase access from a service operator. Changing the machine does not necessarily change who controls admission, capacity allocation or continuity of service. Hardware diversity and customer independence must be assessed separately.

For procurement and system design, substitution has to be tested against the operation that must continue:

| What can change?            | What must be established?                                                                              |
| --------------------------- | ------------------------------------------------------------------------------------------------------ |
| The model supplier          | Can the operator retain and run the released weights under the applicable terms?                       |
| The cost of operating       | Does the alternative meet the actual workload's quality, memory, latency and reliability requirements? |
| The infrastructure provider | Can deployment move in practice, including its software, data and capacity requirements?               |

At the rule, the question is which actor has authority over which activity, development, distribution, access or operation.

In his September essay, Dario Amodei proposes embedded third-party evaluators with continuing access to frontier laboratories, followed by coordination among democratic countries and eventually broader international coordination. He says pacing should allow time for safeguards and verification while training continues. \[9\] The initial mechanism attaches to laboratories and their development processes. Such oversight could affect a model before its weights are released. Once copies are distributed, continuing oversight of the originating laboratory is a different task from supervising every downstream deployment. A rule covering development, one covering distribution and one covering operation would reach different actors. Whether those obligations should overlap is a policy decision; the overlap cannot be assumed from the word "safety."

A September joint US cybersecurity advisory illustrates another point of intervention. It alleges industrial-scale distillation campaigns against US model providers and recommends account monitoring and targeted response alterations, including less capable models for malicious distillation requests. It also describes circumstances in which suspected or confirmed distillers should not be informed of the change, while safety researchers and evaluators should be informed. \[10\]

The mechanism depends on an intermediary that receives the request and controls the response. The alleged distillation targets the hosted frontier model, the source whose outputs are being obtained. Downloadable weights do not remove the provider's ability to monitor or restrict requests made to that source. They change its reach downstream. Once an operator runs a copy independently and offline, intervention through the source provider's API cannot change that copy's responses. This is a boundary of the specific intervention mechanism, not an exemption from oversight or applicable law. Safety coordination and IPO narrative can be analyzed with the same test as a cancellation notice. Ask which actor gains the power to withhold the next training run, the next API, or the next evaluation badge, and whether a customer who already has weights and a rack can ignore that actor. Incentive talk (Michael Burry\[11, 12\]) is a hypothesis about why the rule is being written. It does not answer where control sits after the rule is written. That remains file, rack, rule.

The provider's ability to intervene is also the customer's exposure to intervention. Monitoring, withdrawal and response alteration may protect against misuse; they also place decisions affecting an organization's work in another organization's hands. Independent operation changes that allocation of authority. It can reduce exposure to a remote supplier's decisions while requiring the operator to take responsibility for controls the supplier previously enforced. The substantive question is which party can observe, decide and act at each point in the system, and to whom that party is accountable.

The economic interests are similarly divided. If model access becomes cheaper and easier to substitute, an application business may gain bargaining power. A compute provider may gain additional customers who choose to operate models themselves. A model developer may face price pressure while expanding adoption of its architecture. The direction depends on which service remains scarce, how costly replacement is, and whether a customer can credibly change suppliers. The ability to leave can affect a relationship even when the customer elects to stay; a theoretical alternative that cannot sustain the workload offers less bargaining power.

The question is consequently more precise than whether the industry will consolidate or decentralize. It can do both at different layers. More people may possess model weights while fewer organizations supply the infrastructure that makes them useful. More chip designs may become available while customers continue to depend on a small number of hosted services. More capable independent operation may become technically possible while its legal conditions become more demanding.

A safety measure can reduce a hazard and change the distribution of commercial power. Assessing the first effect does not answer the second. Both deserve evidence: what harm is addressed, which actor must act, what compliance costs, and which alternatives remain available afterward.

The record establishes that supply relationships can put continued access at issue without a technical change; that named licenses permit distribution of some model weights; that developers are publishing efficiency mechanisms and hardware alternatives; and that the oversight and defensive measures examined here intervene at identifiable laboratories, development processes and services.

It does not establish that shared methods transmit containment failures, that active parameter counts demonstrate affordable service, that the advisory's allegations have been independently proved, or that any party intended a particular commercial side effect. Those are separate claims requiring separate evidence.

Let's return, then, to Cursor and the proposed November 12 cutoff. OpenAI's notice concerns one model-supply relationship; it is not a finding that Cursor will stop operating. But the three places make the shape of the problem concrete. Cursor does not possess OpenAI's weights, so substitution at the file is unavailable for that model by construction. What remains is substitution at the rule, renegotiating the relationship, or substitution at the file with a different model, which preserves a service while changing the capability behind it. Continuing a workflow through a substitute could change its performance, behavior or cost; whether any replacement is equivalent is a separate question the notice does not answer.

- The file asks which model can actually be retained and served.
- The rack asks whether the available infrastructure can sustain the required workload.
- The rule asks what the relevant agreements and permissions allow.

Those questions apply whether the customer is a software company, a research institution or a military organization. Continuity of service and continuity of capability are different requirements; a substitution plan has to specify which one it preserves.
