# A4

### Overview

The A4 tokenization model allows for the creation of text-based tokens in the A4 output format.

* [Specifications](/tokenization-models/a4/specifications.md)

***

### Key Features

#### Multiple Pages

The A4 model is designed to consolidate multiple outputs into a single text-based token, incorporating a built-in pagination system. As a result, A4 enables the tokenization of documents with multiple pages.

***

### Intended Use Cases

The A4 tokenization model is designed for tokenizing long text records (e.g., documents). It is intended for use cases where a document requires the highest levels of immutability, permanency, attestability, and auditability of text records. This is particularly applicable in critical contexts that demand the utmost data provenance and integrity.

***

#### Legal

A4 can be used for tokenizing traditional critical legal documents, such as contracts, financial statements, title deeds, and patents.

#### AI

A4 can be integrated into AI-related frameworks, enabling the permanent recording of long text records generated during AI processes. This ensures unparalleled data provenance and integrity — from tokenizing AI model performance reports, explanation documents, and versioning, to tokenizing compliance audits, algorithmic intellectual property (IP), and data provenance and lineage.

#### Literature

A4 can be used for tokenizing critical literature documents, such as research articles, academic papers, technical whitepapers, and manifestos.
