2026 legal update / Reviewed 12 November 2026
The Commission announced enforcement of applicable AI Act rules from 2 August 2026. Businesses integrating general-purpose models should know which evidence their suppliers can provide.
Model provider and system provider are different roles
The Commission’s enforcement framework distinguishes obligations for general-purpose AI models from obligations for AI systems. Integrating a model does not automatically make a business the original model provider, but its own role and modifications must be assessed.
Translate supervision into contract requirements
Ask what documentation, use restrictions, model-change notices and cooperation will be available. Copyright policies and information for downstream providers can be relevant to due diligence. A supplier’s reference to a voluntary code should be evaluated for scope and evidence rather than treated as a blanket compliance warranty.
Four practical examples
Illustrative scenarios, not reports of client mandates. The appropriate response depends on the facts and applicable law.
Enterprise API
A customer seeks reliable notice of model changes and an escalation route for compliance questions before renewing.
Fine-tuned model
A developer examines whether its modifications change its regulatory responsibilities and the evidence it must retain.
Missing documentation
An integrator cannot explain the model’s intended limits. It asks for specific information rather than a general marketing statement.
Supplier investigation
A business reviews dependencies and continuity options if its model provider becomes subject to supervisory measures.
Practical next step
Identify the systems, products or contracts affected, assign a responsible owner and preserve the documents supporting your assessment. Read our related service page for the scope of legal support.
