# Annex XI

*In force · Consolidated version of 27 July 2026 · Checked against EUR-Lex on 30 Sep 2026 ·* [*Official source*](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:02024R1689-20260727)

#### Technical documentation referred to in Article 53(1), point (a) — technical documentation for providers of general-purpose AI models

**Section 1**

**Information to be provided by all providers of general-purpose AI models**

The technical documentation referred to in Article 53(1), point (a) shall contain at least the following information as appropriate to the size and risk profile of the model:

**1.** A general description of the general-purpose AI model including:

**(a)** the tasks that the model is intended to perform and the type and nature of AI systems in which it can be integrated;

**(b)** the acceptable use policies applicable;

**(c)** the date of release and methods of distribution;

**(d)** the architecture and number of parameters;

**(e)** the modality (e.g. text, image) and format of inputs and outputs;

**(f)** the licence.

**2.** A detailed description of the elements of the model referred to in point 1, and relevant information of the process for the development, including the following elements:

**(a)** the technical means (e.g. instructions of use, infrastructure, tools) required for the general-purpose AI model to be integrated in AI systems;

**(b)** the design specifications of the model and training process, including training methodologies and techniques, the key design choices including the rationale and assumptions made; what the model is designed to optimise for and the relevance of the different parameters, as applicable;

**(c)** information on the data used for training, testing and validation, where applicable, including the type and provenance of data and curation methodologies (e.g. cleaning, filtering, etc.), the number of data points, their scope and main characteristics; how the data was obtained and selected as well as all other measures to detect the unsuitability of data sources and methods to detect identifiable biases, where applicable;

**(d)** the computational resources used to train the model (e.g. number of floating point operations), training time, and other relevant details related to the training;

**(e)** known or estimated energy consumption of the model.

With regard to point (e), where the energy consumption of the model is unknown, the energy consumption may be based on information about computational resources used.

**Section 2**

**Additional information to be provided by providers of general-purpose AI models with systemic risk**

**1.** A detailed description of the evaluation strategies, including evaluation results, on the basis of available public evaluation protocols and tools or otherwise of other evaluation methodologies. Evaluation strategies shall include evaluation criteria, metrics and the methodology on the identification of limitations.

**2.** Where applicable, a detailed description of the measures put in place for the purpose of conducting internal and/or external adversarial testing (e.g. red teaming), model adaptations, including alignment and fine-tuning.

**3.** Where applicable, a detailed description of the system architecture explaining how software components build or feed into each other and integrate into the overall processing.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.headlesslaw.com/ai-act/annexes/annex-xi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
