What happened
The US General Services Administration has released the final language of GSAR 552.239-7001, "Basic Safeguarding of Data within Large Language Model Artificial Intelligence Systems." It is a deviation clause and sits within the GSA Acquisition Regulation overhaul, prescribed in GSAR 539.71.
The clause applies where the government is procuring an LLM, generative assistant, chatbot, agentic system, or an LLM-enabled document or productivity tool, in each case where LLM functionality is a material feature and government data will be submitted to or produced by the model. It is self-deleting where LLM use stays inside the contractor's internal business, back-office or performance-support systems that the government does not access, and where LLM functionality is incidental to a product whose primary purpose is not AI. Contractors must flow the clause down to subcontractors performing AI design, development, deployment, or operation and monitoring tasks as described in Appendix A of the NIST AI Risk Management Framework 1.0. Paragraphs covering the origin, ownership, jurisdiction and foreign control of open components and fully open models are excluded from the flowdown requirement.
The substance is strict. The government retains ownership of government data and of custom development, and grants contractors only a limited licence covering contract performance, de-identified security telemetry and authorised support. Prohibited uses of government data include training, fine-tuning or otherwise improving any LLM, including third party models; informing the contractor's advertising, marketing or business decisions; retaining or accessing data beyond the contract's scope and duration; and sharing it with unauthorised parties. Contractors must implement technical, administrative and physical safeguards, restrict access to personnel authorised by the contracting officer, log and time-bound that access, provide zero-persistence architectures and logical segregation from other customers' data, and keep government data inside agreed premises or FedRAMP-authorised services without written consent. Notification of a material violation must reach the contracting officer within 72 hours of the contractor obtaining actual knowledge. Due diligence can be met through flowdowns, subcontractor attestations supported by independently verifiable evidence where practicable, or existing artefacts such as FedRAMP packages, model cards, SOC 2 reports and ISO/IEC 27001 certification, without duplicating documentation. The clause also states that it takes precedence over the contractor's own terms of service and click-wrap agreements.
Why this is a GRC story
The clause is a usable template. Bans on training, retention and cross-customer commingling, backed by named evidence such as SOC 2 and ISO 27001 artefacts, are the questions any organisation should be asking AI vendors.
Flowdown is where programmes break. NIST AI RMF role definitions give a practical way to work out which subcontractors are in scope, rather than relying on who happens to be named in the contract.
The 72-hour notice compresses incident response. Detection, severity assessment and contractual notification now have to be coordinated on a fixed clock, which is a decision that should be rehearsed rather than improvised.
What to watch
Watch whether the clause spreads beyond GSA as the wider federal acquisition overhaul proceeds, and how AI vendors respond to the training prohibition in commercial terms. Attestation is the softer control here, and the clause itself nudges toward independently verifiable evidence, so the interesting question is how agencies verify it.
