What it does

It turns what due diligence found into enforceable rights. A set of standard positions covers the matters particular to AI: whether the supplier may train on the organisation's data, how long it keeps prompts, what notice it gives of model changes and retirement, what information it must provide, who its sub-contractors are, how incidents are reported, who is responsible for what, and how the organisation gets out. Legal owns the positions; procurement applies them; the business owner accepts any departure. It operates at contract and at renewal.

How to implement it

  • Maintain model clauses for each topic, with fallback positions.
  • Prohibit training on the organisation's data unless expressly agreed.
  • Fix retention periods, processing locations and deletion on exit.
  • Require notice of model changes, deprecation and new sub-contractors.
  • Secure rights to documentation, test evidence and audit, scaled to materiality.
  • Allocate responsibility for regulatory duties, including provider and deployer roles.

Evidence it operates

Design: a clause library and negotiating playbook for AI contracts. Operation: executed contracts containing the positions; a log of departures with approver; review records when a supplier changes its terms; settings in the product that match the contract.

Where it fits

At contract, after due diligence and before use. It is the primary control for vendor reuse of organisation data, and supports unannounced upstream model change, sub-outsourcing visibility gap and AI service outage. It gives ongoing AI vendor monitoring the rights it relies on.

Limits

Large providers contract on standard terms that most customers cannot change, and may amend them on notice. A right that is never exercised protects little. Contract terms allocate loss after the event and do not prevent it. Click-through tools adopted by staff have no negotiated contract at all.

Risks this mitigates

Primary mappings

Unallocated liability for AI harm High
Allocates liability, indemnities and insurance with suppliers and customers. Contracts, insurance and internal accountability do not settle who bears the loss when an AI system causes harm.
Vendor reuse of organisation data High
Prohibits or limits the provider's use of the organisation's data for training. A provider uses the organisation's prompts, documents or outputs to train or improve its own models, or keeps and reviews them, beyond what the organisation intended.

Supporting mappings

AI service outage High
Sets availability and support commitments. An inference service, model endpoint or supporting platform becomes unavailable, and the business process that depends on it stops or queues.
Confidential information disclosed to AI tools High
Imposes confidentiality and no-training terms on providers. Trade secrets, legally privileged material or information held in confidence for others are entered into AI tools and leave the organisation's control.
Copyright infringement in training data High
Obtains indemnities. A model is trained or fine-tuned on protected works without a licence or an applicable exception, by the organisation or by a provider whose model it uses.
Cross-border AI data transfer risk Medium
Fixes processing locations and transfer terms in the agreement. Personal data processed by an AI system, often through a cloud or model provider, is sent outside the UK without a valid transfer mechanism.
Excessive retention of prompts and logs Medium
Binds providers to the same limits. Prompts, outputs and conversation histories that contain personal data are kept indefinitely by the organisation or its provider.
Inadequate AI vendor due diligence High
Secures in the contract what diligence found necessary. An AI supplier is taken on without due diligence proportionate to how material its system is, or with a generic assessment that never asks the questions specific to AI.
Infringing AI outputs High
Secures provider indemnity for outputs. Generated text, code or images reproduce protected material, and the organisation publishes, sells or ships them.
Missing provider documentation Medium
Obliges the provider to supply and update it. A provider does not supply the information a deployer or downstream builder needs to assess, integrate and oversee its model.
Model weight theft High
Binds suppliers who hold the weights to equivalent protection. Proprietary weights or fine-tuned adapters are copied from storage, a pipeline or a supplier, taking the intellectual property and enabling attacks to be developed offline.
Sub-outsourcing visibility gap Medium
Requires notice of and consent to changes in sub-suppliers. An AI supplier relies on its own suppliers for models, hosting, data or labelling, and the organisation has no visibility of that chain and no contractual hold over it.
Unannounced upstream model change High
Obliges the provider to give notice. A provider updates, replaces or reconfigures a hosted model, and the organisation's system behaves differently without any change of its own.
Unassessed AI in third-party products High
Requires notice before AI features are introduced. A supplier switches on AI features inside a product already in use, bypassing the organisation's assessment and approval.
Unauthorised commitments by agents High
Terms of use can limit reliance on agent statements. An agent makes a statement, offer or transaction that binds the organisation, without the authority a person in the same position would need.
Uncertain ownership of AI-generated work Medium
Settles ownership of outputs with the provider. The organisation cannot establish or protect rights in material created with AI, because protection depends on human authorship that it cannot show.
Unrecognised provider obligations Medium
Allocates provider and deployer duties with the supplier. An organisation rebrands, substantially modifies or repurposes an AI system and takes on a provider's legal duties without realising it.
