Topic · EU AI Act

Does the EU AI Act apply because an assistant wrote the code?

Using an assistant to write code does not by itself make the shipped software an AI system or a high-risk system. Classify the system you supply or use, its intended purpose and your role. Then identify the applicable duties and dates.

01 · Classification sequence

The product and its use determine the next question.

Follow the questions in order. High-risk systems are a subset of AI systems, not an alternative to containing AI.
  1. 1. Does the supplied product contain an AI system?

    Apply the Article 3 definition to the delivered behavior. If no, AI-assisted authorship alone does not put that software in an AI-system risk class. Separately assess your organisation's use of the coding assistant.

  2. 2. What is the AI system's intended purpose and deployment context?

    Record the function, affected people, decisions and safeguards. Check prohibited practices first. Then assess the Annex I product-safety route or Annex III use cases under Article 6, including the conditions and exceptions. For other AI systems, check duties such as Article 50 transparency.

  3. 3. Which role does your organisation perform?

    Identify provider, deployer, importer or distributor responsibilities for this system. An organisation can hold more than one role. Building on another provider's model does not automatically make you that model's provider.

  4. 4. Which obligations apply to that role, route and date?

    Use the amended law, including Article 2 scope rules, Article 25 changes of responsibility and transitional provisions. Record the rationale and owner before turning obligations into requirements and evidence requests.

For example, ordinary payroll software written with an assistant differs from a product using AI to rank job applicants. The latter raises an Annex III employment-use question. A chat interface raises its own purpose and transparency questions; it is not automatically high-risk.

The Annex I route concerns an AI system that is itself a regulated product or its safety component, together with the applicable third-party conformity-assessment condition. The July 2026 amendment clarifies the safety-component boundary. Merely adding an AI convenience feature does not establish that route; a failure that can endanger health or safety matters. Annex I Section B products follow sector-specific rules under Article 2(2).

02 · Responsibility

Separate supplying the system from using it.

Provider

Develops, or has developed, an AI system and places it on the market or puts it into service under its own name or trademark. A provider can also place a general-purpose AI model on the market. Payment is not required for the definition.

Deployer

Uses an AI system under its authority, outside personal, non-professional activity. An employer using an applicant-ranking system and the supplier providing that system answer different responsibility questions.

Articles 16 and 26 assign different duties to high-risk providers and deployers. Rebranding, substantial modification or changing an intended purpose can shift responsibility under Article 25. Keep the model provider, system provider and deploying organisation explicit in the evidence record.

03 · Amended application dates

The July 2026 amendment changed the high-risk timetable.

Regulation (EU) 2026/1744, the Digital Omnibus on AI, entered into force on 27 July 2026. These dates reflect that adopted amendment, not the original 2024 timetable.

  • 2 February 2025: the initial prohibited-practice and AI-literacy provisions began applying.
  • 2 August 2025: governance and general-purpose AI model provisions began applying, subject to their transitional rules.
  • 2 August 2026: general application date, including Article 50 transparency duties, with the specified exceptions.
  • 2 December 2026: the amendment's new prohibitions concerning non-consensual sexual deepfakes and child sexual abuse material apply. This is also the Article 50(2) marking deadline for the specified systems placed on the market before 2 August 2026.
  • 2 December 2027: Chapter III Sections 1–3, except Article 6(5), apply to high-risk systems under Article 6(2) and Annex III.
  • 2 August 2028: those provisions apply to high-risk systems under Article 6(1) and Annex I, with the relevant sector-specific scope rules.

Article 111 contains further transition rules, including for existing systems. Establish the system's market-entry and modification history before assigning a deadline. The Commission's updated timeline is a useful navigation aid.

04 · Engineering evidence map

Connect each duty to evidence and an accountable owner.

For high-risk systems subject to these provisions, a connected engineering record can supply part of the evidence below. The final column identifies the wider system or organisational work. This is a preparation map, not an assertion that Proof implements every collection or assessment step.

ProvisionUseful engineering contributionWider responsibility
9 · Risk managementLink a foreseeable hazard to a control requirement, the affected implementation, pre-set acceptance criteria and an executed check. Preserve failures and residual questions when a Change is reviewed.Maintain the lifecycle risk-management process, evaluate reasonably foreseeable misuse and affected people, and decide whether residual risk is acceptable.
10 · Data governanceRecord the data version and origin used by a check, its intended population and conditions, and known coverage or quality limits. Link a data-related failure to the requirement it challenges.Establish the required governance and quality of training, validation and testing data, as applicable. The amended Article 10 also addresses testing data for systems developed without model-training techniques.
11 · Technical documentationSupply traceable design decisions, requirements, implementation references, verification results and Change history for the technical file.Compile and maintain the complete Annex IV documentation. The amendment extends the simplified documentation route to small mid-cap enterprises as well as SMEs and startups.
12 · Record-keepingSpecify which operational events must be logged and verify logging behavior, including failure cases and changes to event meaning.Provide the required automatic event logging in the deployed system and fulfil the applicable retention and operational duties. A development record supplies context for those logs.
14 · Human oversightTurn an oversight design into checkable behavior: display limits, enable intervention, and test the relevant override or stop path under defined conditions.Design effective oversight during use and assign people with the necessary competence, authority and support. A merge approval is not deployed-system oversight.
17 · Quality managementKeep requirements, review decisions, checks, unresolved findings and Changes connected so the quality process can inspect how a design decision was implemented.Establish and operate the documented quality-management system. Amended proportionality for SMEs, startups and small mid-cap enterprises retains the required level of rigour and protection.
72 · Post-market monitoringWhen an operational signal is supplied, connect it to an affected requirement, investigate it and retain the corrective Change and its verification. This preserves the route from observed failure to engineering action.Operate lifecycle performance-data collection and analysis and maintain the monitoring plan in the technical documentation. The amendment calls for Commission guidance, including a voluntary template, by 2 September 2027.

The mapping uses the amended provisions, including the changes to Articles 10, 11, 17 and 72. Some Service Desk article pages still reproduce the original June 2024 text; use the amendment and consolidated version when checking a particular obligation.

05 · A bounded starting point

Take one risk through a requirement and an observed result.

Illustrative example: an AI-assisted assessment must route an uncertain result to a human reviewer. The responsible team approves the intended behavior and acceptance criteria. The evidence record identifies the implementation, model and evaluation-data versions, the check that ran, its result and any cases outside the tested conditions. A later model or workflow change raises the question of whether that evidence still supports the requirement.

That record helps a reviewer inspect one control. Evaluation coverage, effectiveness of the deployed review process and system-wide risk acceptance still need their own evidence and responsible owners.

Proof today: its graph connects requirements, hazards, code, Changes and verification records, retaining the context for a review and making it available to agents. Development direction: model- and data-aware AI evaluation integrations, operational monitoring connections, release tracking and regulatory profiles. These are not a completed AI Act assessment service.

Bring one AI-related Change and its required evidence to scope a walkthrough. For engineering practice around assistants writing software, see AI4SDLC requirements and testing; that US guidance is a separate source.
