EU AI Act Article 13, line by line.

Article 13 binds the provider of a high-risk AI system to give the deployer instructions for use sufficient to interpret what the system produces — including the logs Article 12 requires it to keep. The two articles are paired obligations: the artefact (12) and the manual to read it (13). Both sit in Chapter III, Section 2, and both apply on 2 December 2027 for Annex III standalone high-risk systems, deferred from 2 August 2026 by the Digital Omnibus (Regulation (EU) 2026/1744, OJ L 2026/1744, 24 July 2026); Annex I embedded systems follow on 2 August 2028, subject to Article 2(13). Read together, they are the regulator-recognised shape of an evidence package.

Warrant is regulator-grade evidence infrastructure for AI agents in regulated industries: drop an agent's execution trace, get a record mapped to a specific EU AI Act obligation, independently verifiable without contacting Warrant.

01 · THE LOAD-BEARING PAIRING

The artefact and the manual.

Article 12 binds the provider to record events automatically over the lifetime of the high-risk AI system. Article 13 binds the same provider to deliver an interpretive layer for those records. Without 13, the logs from 12 are technically present but interpretively useless. A column of timestamps, action types, and tensor shapes does not, on its own, tell a deployer whether the system behaved within its intended purpose, whether human oversight fired correctly, or whether an output sits inside the documented accuracy envelope.

The opening of Article 13 paragraph 1 fixes the principle:

High-risk AI systems shall be designed and developed in such a way as to ensure that their operation is sufficiently transparent to enable deployers to interpret a system's output and use it appropriately. Regulation (EU) 2024/1689 · Article 13(1) · 13 June 2024

Read alongside Article 12(1), the structure becomes explicit. Article 12(1) says the system shall technically allow for the automatic recording of events. Article 13(1) says the system shall be designed... to ensure that their operation is sufficiently transparent to enable deployers to interpret. One records. The other interprets. The two articles describe the two halves of a single regulator-readable artefact.

Placement matters. Article 13 sits inside Section 2 of Chapter III, the requirements the provider must satisfy before placing the system on the Union market. Article 16(a) reads those requirements back as a provider obligation — providers shall ensure that their high-risk AI systems are compliant with the requirements set out in Section 2. Article 99(4)(a) reads Article 16 back as a fineable failure. The same three steps that take Article 12 to the EUR 15 million ceiling take Article 13 there too.

02 · ART. 13 § 1 VERBATIM

Paragraph 1 · the transparency principle.

High-risk AI systems shall be designed and developed in such a way as to ensure that their operation is sufficiently transparent to enable deployers to interpret a system's output and use it appropriately. An appropriate type and degree of transparency shall be ensured with a view to achieving compliance with the relevant obligations of the provider and deployer set out in Section 3. Regulation (EU) 2024/1689 · Article 13(1) · 13 June 2024

Three load-bearing phrases. Sufficiently transparent sets a functional bar, not a maximum disclosure mandate. Interpret the system's output ties transparency to the operational read of decisions, not to the model's internals. Use it appropriately hooks the obligation into the deployer's downstream duty under Article 26.

Recital 72 makes the operational frame explicit: transparency is required to address concerns related to opacity and complexity of certain AI systems and help deployers to fulfil their obligations under this Regulation, so that deployers can understand how the system works, evaluate its functionality and comprehend its strengths and limitations. It is not transparency for its own sake, and it is not addressed to the affected person — an affected person's right to an explanation of an individual decision sits separately in Article 86.

"Article 12 builds the artefact. Article 13 ships the manual to read it. One record satisfies both."Warrant Compliance · 2026-05-09
03 · ART. 13 § 2 · INSTRUCTIONS FOR USE

Paragraph 2 · the six mandatory elements.

Paragraph 2 fixes the format, paragraph 3 fixes the content. Together they describe what regulators will read.

High-risk AI systems shall be accompanied by instructions for use in an appropriate digital format or otherwise that include concise, complete, correct and clear information that is relevant, accessible and comprehensible to deployers. Regulation (EU) 2024/1689 · Article 13(2) · 13 June 2024

Paragraph 3 then enumerates the information elements the instructions for use must contain — six of them, points (a) to (f), prefaced by at least:

§ 3(a)
Identity and contact details of the provider, and where applicable, of its authorised representative. IMPLICATION · the deployer must know who placed the system on the market, including the Article 22 representative for non-Union providers.
§ 3(b)
Characteristics, capabilities and limitations of performance of the high-risk AI system, set out in seven sub-points (i) to (vii): intended purpose; level of accuracy with its metrics, robustness and cybersecurity referred to in Article 15; known or foreseeable circumstances including reasonably foreseeable misuse; technical capabilities to explain the output; performance on specific persons or groups; specifications for the input data and the training, validation and testing data sets; and information enabling the deployer to interpret the output. IMPLICATION · the operational envelope is part of the deliverable, not part of an internal document.
§ 3(c)
Changes that have been pre-determined by the provider at the moment of the initial conformity assessment, if any. IMPLICATION · the version line is binding. Anything outside it is a substantial modification under Article 25.
§ 3(d)
The human oversight measures referred to in Article 14, including the technical measures put in place to facilitate the interpretation of the outputs of high-risk AI systems by the deployers. IMPLICATION · the human-in-loop checkpoints are documented at the instruction level, not just at the system level.
§ 3(e)
The computational and hardware resources needed, the expected lifetime of the high-risk AI system, and any necessary maintenance and care measures, including their frequency, to ensure the proper functioning of that AI system, including as regards software updates. IMPLICATION · infrastructure, lifetime and update cadence are one element, not two. The list ends at (f); there is no point (g).
§ 3(f)
Where relevant, a description of the mechanisms included within the high-risk AI system that allows deployers to properly collect, store and interpret the logs in accordance with Article 12. IMPLICATION · this is the explicit Article 12 cross-reference, and the last point in the list. The instructions tell the deployer how to read the logs.

Notice the structural shape. Three of the six elements are about the system's behaviour at decision time (b, d, f). One is about its boundaries (c). Two are about the responsible party and the resources it needs (a, e). Paragraph 3 opens with at least, so six is the floor, not the ceiling. The instructions are an operating manual for a regulated artefact, not a marketing description.

04 · ART. 13 § 3 · PERFORMANCE

Paragraph 3 · accuracy, robustness, cybersecurity.

Paragraph 3 sub-clause (b) is the longest in Article 13 and carries the heaviest performance disclosure burden. It requires the provider to document:

the characteristics, capabilities and limitations of performance of the high-risk AI system, including its intended purpose, the level of accuracy, including its metrics, robustness and cybersecurity referred to in Article 15 against which the high-risk AI system has been tested and validated and which can be expected, and any known and foreseeable circumstances that may have an impact on that expected level of accuracy, robustness and cybersecurity. Regulation (EU) 2024/1689 · Article 13(3)(b), opening words with points (i) and (ii) · 13 June 2024

The accuracy and robustness language pairs directly with Article 9 risk management and Article 15 accuracy, robustness and cybersecurity. Article 13 is where the testing and validation results actually leave the provider's premises and reach the deployer. The accuracy metric is not aspirational. It is the metric the system was tested against and the metric the deployer can expect in production within the documented operating conditions.

Sub-clause (b) also requires disclosure of any known or foreseeable circumstance, related to the use of the high-risk AI system in accordance with its intended purpose or under conditions of reasonably foreseeable misuse, which may lead to risks to the health and safety or fundamental rights. This is the foreseeable-misuse vector, and it carries direct implications for agentic systems treated in section 09 below.

05 · CROSS-REFERENCE TO ART. 12

Why 12 and 13 are one obligation in two articles.

The cross-reference is explicit and load-bearing. Article 13(3)(f) requires the instructions for use to include the following:

a description of the mechanisms included within the high-risk AI system that allows deployers to properly collect, store and interpret the logs in accordance with Article 12. Regulation (EU) 2024/1689 · Article 13(3)(f) · 13 June 2024

The verb chain is the regulator's specification: collect, store, interpret. Three operations on the same artefact. Article 12 mandates that the artefact exists. Article 13 mandates that the deployer is told how to do all three operations on it. Without the Article 13 instructions, the Article 12 logs are technically present but interpretively useless.

The pairing closes a loop on the deployer side. Article 26(6) requires the deployer to keep the logs automatically generated by the high-risk AI system to the extent such logs are under their control. The mechanism for keeping them, and the schema for reading them, comes from the provider's Article 13 instructions. The triangle of obligations is closed: Article 12 produces, Article 13 explains, Article 26 retains and uses.

Annex IV carries the instructions into the technical documentation file, but not the logs. Annex IV point 1(h) requires instructions for use for the deployer, and a basic description of the user-interface provided to the deployer, where applicable, and point 2(e) cross-refers expressly to Article 13(3), point (d) on human oversight. Annex IV does not mention Article 12 at all: the logs are kept under Article 19(1) by the provider and Article 26(6) by the deployer, and produced to a competent authority on a reasoned request under Article 21(2). The instructions are filed; the logs are retained and produced.

06 · WHERE WARRANT LIVES

One evidence package, and what it does not hold.

Warrant produces the Article 13 half of the pairing. The signed record is a closed structure — its root properties are exactly classification, actions, authorizations, obligations, coverage_by_regime, deferred_regimes, risk_tier, refusal_reason and trace_metadata, and additionalProperties is false, so nothing else can be present. What it carries is the interpretive layer: which sub-clause of which obligation was engaged on each action, the per-action authorisation assessment, and the coverage summary per regime.

It does not carry the submitted trace. The inputs, outputs, intermediate tool calls and per-action timestamps a customer sends in are read during extraction and are not re-emitted into the signed record; each actions row retains exactly action_id, actor, action and subject, and no field points back into the source trace. Article 12 log-keeping therefore stays with the provider's own logging system. The gap is stated rather than papered over: the package is what makes those logs readable by clause, not a replacement for them.

A live sample sits at /verify?id=7de85ceaeac42a47. The package contains the classification, the extracted actions rows, the per-action authorisation assessment, the obligation map back to Article 13(3)(a) through (f) keyed by action id, and a record that is independently verifiable without contacting Warrant. It is an input to the Annex IV technical documentation file, not a separate marketing artefact.

W
Sample EU evidence package · Warrant registerINDEPENDENTLY VERIFIABLE
→ /v/7de85ceaeac42a47

The boundary is deliberate. The Article 13 interpretive layer is the part that has to be readable by a stranger, and it is the part that is signed. Keeping the raw trace out of the signed record keeps the customer's inputs and outputs in the customer's own systems, where Article 12 and Article 19 already put them. What that costs is stated plainly above: a reader holding a Warrant package cannot re-derive the underlying trace from it, and must obtain the logs from the provider or the deployer to do so.

07 · THE DEPLOYER'S READ

What the deployer actually receives.

Annex IV requires the technical documentation file. The deployer reading a Warrant package, at the point of system handover or at the point of regulator inquiry, gets two layers and one stated gap.

  • The interpretive layer · the classification (which Annex III area), the extracted actions rows carrying action_id, actor, action and subject, the per-action authorisation assessment in authorizations, and the obligation map citing Article 13(3)(a) through (f), keyed by action id. This is the Article 13 material.
  • The verification layer · the package is independently verifiable without contacting Warrant, and any edit shows up at confirmation time. This is the Article 13(3)(b) cybersecurity disclosure made operational.
  • The gap, stated · the submitted trace is not in the package. Inputs, outputs, intermediate tool calls and per-action timestamps are read during extraction and are not re-emitted, and no field addresses back into the source trace. Article 12 log-keeping is not discharged by this record and is not claimed to be.

The verification layer is not decorative. Article 15(5) requires that high-risk AI systems be resilient against attempts by unauthorised third parties to alter their use, outputs or performance. A record that is independently verifiable without contacting Warrant is the post-hoc analogue of that requirement. The reader confirms the record, not the producer's good word.

08 · FIELD MAPPING

Article 13 sub-clauses against the fields that exist.

Each sub-clause of Article 13 paragraph 3 is set below against the field in the evidence package that carries it. Three of the six have a field, and it covers part of what the sub-clause asks for. Three have none, and the third column says so.

Art. 13 sub-clause What evidence must show warrant-v1 field, or none
§ 3(a) Provider identity and authorised representative None. actions[].actor carries the actor string supplied in the trace, which is not a provider identity and never an authorised representative.
§ 3(b) Capabilities, limits, accuracy, robustness, cybersecurity classification.domain, .jurisdictions, .risk_tier and .risk_tier_justification. classification.regimes is defined in the schema but is left empty in production, so it is not data a reader can rely on. No field for accuracy, robustness or cybersecurity.
§ 3(c) Pre-determined changes, version at decision time pipeline_models and pipeline_config_sha256 on the receipt, which record which models and which prompt configuration reached the conclusion. Neither is a version of the provider's own system, and no field records pre-determined changes.
§ 3(d) Human oversight measures, when human-in-loop fired authorizations[].human_oversight_appropriate per action, and incomplete_oversight_count on the receipt. The first is Warrant's assessment of whether human oversight was appropriate for that action, not a record that a human was present or intervened. Neither records the oversight measures the provider designed in.
§ 3(e) Compute and hardware resources, expected lifetime, maintenance and software updates None.
§ 3(f) Log retrieval and interpretation mechanisms trace_metadata.package_id is the identifier the record is retrieved by; obligations is an object keyed by action id, so the clause id sits at obligations.<action_id>[].id, and coverage_by_regime summarises them per regime.

Read the third column literally. The evidence schema sets additionalProperties to false at the top level, and its root properties are exactly classification, actions, authorizations, obligations, coverage_by_regime, deferred_regimes, risk_tier, refusal_reason and trace_metadata. There is no metadata root and no regulator_evidence root, so no path beneath either can appear in a conforming package. classification is closed the same way, which rules out any scope_envelope property on it. Where the column says None, no field exists — not a field under a different name.

What the structure delivers is narrower than what Article 13(3) asks for. A deployer, or a national competent authority running an Article 21 access request, can read the package by clause number: each obligation row carries the corpus clause id, a compliance status and an evidence string, and coverage_by_regime summarises them per regime. Article 13(3)(a) and (e), and the accuracy, robustness and cybersecurity limbs of (b), have no field. For those the instructions-for-use file remains the provider's own document, and the package does not stand in for it.

09 · FORESEEABLE MISUSE

Article 13(3)(b) and the agentic AI vector.

Article 13(3)(b)(iii) requires the provider to disclose any known or foreseeable circumstance, related to the use of the high-risk AI system in accordance with its intended purpose or under conditions of reasonably foreseeable misuse, which may lead to risks to the health and safety or fundamental rights referred to in Article 9(2). For classical machine-learning systems, the foreseeable-misuse vector is well-understood: distribution shift, adversarial inputs, data drift outside the validation envelope.

For agentic AI systems, three new vectors require disclosure. Each is foreseeable in the regulatory sense: the technical literature describes them, the threat is published, and a reasonable provider should know.

  • Prompt injection within trace data. A user input or a downstream tool output that contains adversarial instructions can hijack the agent's chain of action. The disclosure must say what the system does when it detects suspicious input patterns and what residual exposure remains after detection.
  • Tool misuse. An agent with access to a transactional API can be steered into actions outside its intended purpose by a sufficiently well-crafted prompt. The disclosure must cover the action allow-list, the authorisation envelope, and the rollback path.
  • System-prompt leak. An agent that exposes its system prompt under adversarial pressure leaks the boundary of its own operating constraints. The disclosure must cover the leak surface and the system-prompt redaction strategy.

Warrant's adversarial robustness eval treats all three vectors as in-scope under Article 13(3)(b). The eval methodology and its results sit at /blog/regulator-grade-evals. The output of the eval becomes a structured disclosure section inside the instructions for use. Agentic AI does not get a discount on Article 13. It gets an expanded disclosure surface.

10 · APPLICATION TIMING

Application timing · 2 December 2027 and the Digital Omnibus.

Article 113 of the AI Act as enacted set the application date for high-risk AI systems under Annex III at 2026-08-02. The Digital Omnibus on AI defers that date to 2027-12-02: Article 1(40)(b) of Regulation (EU) 2026/1744 (OJ L, 2026/1744, 24 July 2026, in force 27 July 2026) replaced Article 113, third paragraph, point (c) with two fixed calendar dates — 2 December 2027 for Article 6(2) and Annex III systems, and 2 August 2028 for Article 6(1) and Annex I, the latter read with the new Article 2(13) under which Articles 9 to 15 and 17 to 25 may be limited where Annex I Section A legislation gives equivalent or higher protection. From the applicable date, a provider that places an Annex III high-risk AI system on the Union market without an Article 13-shaped instruction-for-use deliverable is exposed to Article 99(4) at EUR 15 million or 3 percent of total worldwide annual turnover for the preceding financial year, whichever is higher.

11 · FAQ

Questions a compliance officer asks first.

Is Article 13 a duty to explain the AI?

Article 13 is narrower than a generic duty to explain. The operative phrase is sufficiently transparent to enable deployers to interpret a system's output and use it appropriately. It is a duty to ship the interpretive layer that lets the deployer read the system's behaviour and discharge its own Article 26 obligations. It is not a duty to publish a full mechanistic account of the underlying model.

What counts as instructions for use under Article 13, a PDF, a wiki, a video?

Article 13 paragraph 2 says high-risk AI systems shall be accompanied by instructions for use in an appropriate digital format or otherwise. The form is open. The content is closed: paragraph 3 lists six mandatory elements, points (a) to (f), and opens with at least, so six is the floor. A PDF, a versioned wiki, or a structured digital document inside the technical documentation file under Annex IV all qualify, provided they cover all six elements and are updated when the system is. A video alone is unlikely to satisfy the concise, complete, correct and clear test in paragraph 2 because the regulator cannot easily quote from it.

Can a deployer rely on the provider's instructions, or must the deployer adapt them?

Both. Article 13 obligates the provider to ship instructions sufficient to operate the system. Article 26(1) obligates the deployer to take appropriate technical and organisational measures to ensure they use such systems in accordance with the instructions for use. A deployer that ignores the instructions absorbs the operational obligation. A deployer that follows them anchors back to provider responsibility for any defect in those instructions.

What is the difference between Article 13 (provider) and Article 26 (deployer)?

Article 13 is provider-side: build the system to be transparent, ship the instructions. Article 26 is deployer-side: follow the instructions, monitor operation, keep your share of logs, suspend on detected risk. The two articles are designed to interlock. Article 13(3)(f) tells the provider to document the log mechanisms. Article 26(6) tells the deployer to keep those logs. Together they form a closed evidentiary loop.

How do Article 13 paragraph 3 cybersecurity disclosures interact with NIS2 Directive obligations?

Article 13(3)(b) requires disclosure of cybersecurity properties and known vulnerabilities relevant to the system. NIS2 (Directive (EU) 2022/2555) imposes broader operational cybersecurity obligations on essential and important entities. The two regimes overlap when a high-risk AI system is operated by a NIS2-regulated entity. Article 13 disclosures feed the deployer's NIS2 risk-management documentation. Both regimes can be enforced in parallel by competent authorities.

Can a model card serve as an Article 13 instruction-for-use?

Only if it covers all six mandatory elements in Article 13 paragraph 3, points (a) to (f). A typical model card documents capabilities, performance metrics, and limitations, which lands roughly on (a) provider identity and (b) characteristics. It rarely covers (d) human oversight technical measures, (e) lifetime, maintenance and software updates, or (f) log interpretation mechanisms with the specificity Article 13 requires. A model card is a starting input. It is not, on its own, a discharge.
