Technical

General-purpose AI (GPAI) model

Model trained at scale with broad task generality.

How the laws define this

Regulatory authorities consistently define a general-purpose AI model around its core capability to perform a wide range of distinct tasks across domains rather than a single narrowly defined function, allowing it to serve as a basis or foundation for downstream AI systems. Divergences center on whether the definition attaches explicit compliance obligations or technical criteria. Regulation (EU) 2024/1689 (Artificial Intelligence Act), including its application under the Windsor Framework, links this classification directly to legal duties, imposing transparency and copyright rules on all providers while mandating stricter requirements for models posing systemic risks due to high computational power or widespread impact. Conversely, the AI – Here for Good: National AI Strategy Refresh (2024) treats the concept as a category requiring tailored national oversight aligned with EU measures. Technically, the GPAI Agentic AI Systems Framework highlights training on vast data and clarifies that models remain distinct from systems, whereas the General-Purpose AI Code of Practice stresses adaptiveness across specific uses like natural language processing, image recognition, and data analysis.

What it triggers

  • Under the EU AI Act, providers of GPAI models face rules on transparency and copyright, with additional, more stringent requirements for those posing systemic risks.source
  • Under the EU AI Act, GPAI model providers must publish summaries of their training content using the training-data transparency template when placing models on the Union market or putting them into service in the Union.source
  • Under the EU AI Act, providers of GPAI models capable of performing a wide range of tasks are subject to specific obligations, especially where they pose systemic risks.source

Definitions (7)

An AI model that is capable of performing a wide range of tasks and can be integrated into various downstream AI systems and applications. These models are often foundational, meaning they can be adapted to numerous specific uses across different domains, such as natural language processing, image recognition, and data analysis.

AI models, including large language models, capable of performing a broad range of distinct tasks, even those for which they were not explicitly trained; providers of GPAI are subject to specific transparency, documentation, and additional obligations where they pose systemic risk.

Models intended to perform a wide range of tasks across domains rather than a narrowly defined function; the Refresh recognises GPAI as a distinct category requiring tailored oversight and alignment with EU-level measures due to their broad capabilities and impacts.

Powerful AI models capable of performing a wide range of tasks, which can underpin various AI systems and may carry systemic risks, necessitating specific obligations for their providers, especially those with significant computational power or widespread impact.

AI models, often large language models, that are capable of competently performing a wide range of distinct tasks and are typically trained on vast amounts of data. These models can form the basis of AI systems but are distinct from them.

These are AI models capable of performing a wide range of distinct tasks, often used as a basis for other AI systems. The Act introduces rules on transparency and copyright for all GPAI models, with additional, more stringent requirements for those identified as posing systemic risks.

Models that meet the AI Act’s definition of systems designed to perform a wide range of tasks and that can be adapted for different downstream uses; the Template applies specifically to such GPAI models when placed on the Union market or put into service in the Union.

Not to be confused with

General-Purpose AI System

A General-Purpose AI System is an AI system based on a GPAI model serving multiple purposes, whereas GPAI refers to the underlying model itself.

Questions and answers

What obligations apply to GPAI models under the EU AI Act?

Providers of GPAI models must comply with transparency and copyright rules. Those posing systemic risks face additional stringent requirements. Specific obligations apply to powerful models with significant computational power or widespread impact.

When does the training-data transparency template apply to GPAI models?

The template applies to GPAI models when they are placed on the Union market or put into service in the Union.

What are systemic risks for GPAI models?

Systemic risks arise from powerful GPAI models with significant computational power or widespread impact, triggering specific obligations for providers under the EU AI Act.
