Free template — Article 11 / Annex IV
Free Annex IV Template
An editable technical documentation template covering every section required by Annex IV of the EU AI Act — no sign-up, no consultant fees, no guesswork.
Aligned with Annex IV, referenced from
Providers save consultant fees; the template covers all nine mandatory Annex IV sections and cites the relevant subparagraphs inline so you can trace every field back to the regulation.
Who needs Annex IV documentation?
Article 11(1) makes technical documentation a provider obligation — the duty belongs to whoever places the high-risk AI system on the EU market or puts it into service under their own name.
- Providers of high-risk AI systems listed in Annex III or regulated as safety components under Annex I
- Documentation must be drawn up before the system is placed on the market or put into service
- Must be kept up to date throughout the system's lifecycle and retained for 10 years after market placement (Art. 18)
- SMEs and start-ups may provide Annex IV in a simplified manner — the simplified template is to be established by the Commission (Art. 11(1) final subparagraph)
Deployers do not draw up Annex IV documentation themselves, but may become providers under Article 25 if they substantially modify the system or put their own name on it.
What the template includes
Nine structured sections, one-to-one with the Annex IV requirements of Regulation (EU) 2024/1689 — the same sections used by the Witness online generator.
General description of the AI system
Annex IV(1)Intended purpose, provider, version, hardware/software interaction, distribution forms, user interface, instructions for use and foreseeable misuse.
Detailed description of elements and development process
Annex IV(2)Development methods, design choices, architecture, training data, validation and testing, metrics, bias detection and cybersecurity per Art. 15.
Monitoring, functioning and control
Annex IV(3)Capabilities and limitations, expected accuracy, human oversight specifications, input data and logging capabilities per Art. 12.
Appropriateness of performance metrics
Annex IV(4)Justification of why the chosen accuracy, robustness and fairness metrics are appropriate for this specific system and intended purpose.
Risk management system
Annex IV(5) / Art. 9Detailed description of the risk management system — identification, estimation, evaluation and mitigation across the full AI lifecycle.
Changes through lifecycle
Annex IV(6)Relevant changes made by the provider over the system's lifecycle — model updates, retraining, configuration changes and substantial modifications.
Standards and specifications applied
Annex IV(7)Harmonised standards applied, common specifications under Art. 41 or alternative technical solutions adopted to meet Chapter III, Section 2.
EU declaration of conformity
Annex IV(8) / Art. 47Copy of the EU declaration of conformity identifying the provider, the system, the regulation and confirming conformity with Chapter III, Section 2.

Frequently asked questions
Who must complete Annex IV documentation?
Providers of high-risk AI systems must draw up the technical documentation set out in Annex IV. This obligation is set by Article 11(1) and applies to anyone who develops a high-risk AI system and places it on the EU market or puts it into service under their own name or trademark. Deployers do not draw up Annex IV themselves, but can become providers under Article 25 if they substantially modify the system or put their own name on it.
When must the Annex IV documentation be completed?
Article 11(1) requires the technical documentation to be drawn up before the high-risk AI system is placed on the market or put into service. It must be kept up to date throughout the system's lifecycle — any substantial modification, retraining or material change in intended purpose triggers an update.
Must I keep it on file after the system is on the market?
Yes. Article 18 requires providers to keep the technical documentation, the quality management system documentation, approvals of changes, decisions of notified bodies, the EU declaration of conformity and automatically generated logs at the disposal of national competent authorities for 10 years after the AI system has been placed on the market or put into service.
What happens if we skip it?
Not drawing up or maintaining Annex IV documentation is non-compliance with Article 16 (provider obligations) and Article 11 (technical documentation). Under Article 99, non-compliance with obligations other than prohibited practices can trigger administrative fines of up to 15,000,000 EUR or 3 percent of worldwide annual turnover, whichever is higher.
Is this template legally binding?
No. The template is a structured starting point aligned with Annex IV. The legal obligation is to produce complete Annex IV documentation covering all nine sections; using this particular template is not required by law. Witness does not warrant that filling in this template alone is sufficient to discharge the technical documentation obligation.
What about the SME simplified form?
Article 11(1), final subparagraph allows SMEs and start-up providers to provide the Annex IV elements in a simplified manner. The Commission is mandated to establish a simplified technical documentation template adapted to SME and start-up needs. Until that template is published you can use this template as a starting point; the underlying obligation to cover the Annex IV elements still applies.
