Well-funded French AI startup Mistral is content to go its own way.
In a sea of competing reasoning models, the company has introduced Mistral OCR, a new optical character recognition (OCR) API designed to provide advanced document understanding capabilities.
The API extracts content — including handwritten notes, typed text, images, tables and equations — from unstructured PDFs and images with high accuracy, presenting in a structured format.
Structured data is information that is organized in a predefined manner, typically using rows and columns, making it easy to search and analyze. Names, addresses and financial transactions are examples of structured data that is stored in spreadsheets or databases. Unstructured data, on the other hand, lacks any specific structure or format, which makes it difficult to analyze and process. This category includes a variety of data types such as social media posts and videos. It also includes audio files, images, and audio files.
Understanding the differences between these data types is crucial for businesses looking to effectively manage and leverage their information assets.

With multilingual support, fast processing speeds and integration with large language models (LLMs) for document understanding, Mistral OCR is positioned to assist organizations in making their documentation AI-ready.
Given that — according to Mistral’s blog post announcing the new API — 90% of all business information is unstructured, the new API should be a huge boon to organizations seeking to digitize and catalog their data for use in AI applications or internal/external knowledge bases.
Mistral sets a new gold standard for OCR
Mistral OCR aims to improve how organizations process and analyze complex documents.
Unlike traditional OCR solutions that primarily focus on text extraction, Mistral OCR is designed to interpret various document typographical elements and characters, including tables, mathematical expressions and interleaved images, while maintaining structured outputs.
According to Mistral’s chief science officer Guillaume Lample, this technology represents a significant step toward wider AI adoption in enterprises, particularly for companies seeking to simplify access to their internal documentation.
The API is already integrated into Le Chat, which millions of users rely on for document processing.
Now, developers and businesses can access the model via la Plateforme, Mistral’s developer suite.
The API is also expected to become available through cloud and inference partners and will offer on-premises deployment for organizations with high-security requirements.
Advancing an early (70-year-old) computing technology
OCR technology has played a significant role in automating data extraction and document digitization for decades. The first commercial OCR machine was developed in the 1950s by David Shepard and his colleagues Harvey and William Lawless Jr., who founded Intelligent Machines Research Co. (IMR) to bring the technology to market.
The system gained traction when Reader’s Digest became its first major customer, followed by banks, telecom companies like AT&T and major oil firms.
In 1959, IBM licensed IMR’s patents and introduced its own OCR machine, formalizing the term as the industry standard.
Since then, OCR technology has continued to evolve, incorporating AI and ML to improve accuracy, expand language support and handle increasingly complex document formats, and can be found in such leading enterprise software as PDF reader Adobe Acrobat.
Mistral OCR represents the next step in this evolution, as it leverages AI to enhance document comprehension beyond simple text recognition.
Benchmarks show the power of Mistral OCR
Mistral highlights its OCR’s competitive edge over existing tools, citing benchmark tests where it outperformed major alternatives including Google Document AI, Azure OCR and OpenAI’s GPT-4o.
The model achieved the highest accuracy scores in math recognition, scanned documents and multilingual text processing.
Mistral OCR is also designed to operate faster than competing models and is capable of processing up to 2,000 pages per minute on a single node.
This speed advantage makes it suitable for high-volume document processing in industries such as research, customer service and historical preservation.
Sophia Yang, head of developer relations at Mistral, has been actively showcasing the OCR capabilities on her X account. Notably, she highlighted its top-tier performance benchmarks, multilingual support and ability to accurately extract mathematical equations from PDFs.
In a recent post, she shared an example of Mistral OCR successfully recognizing and formatting complex mathematical expressions, reinforcing its effectiveness for scientific and academic applications.
Key features and use cases
Mistral OCR introduces several features that make it a versatile tool for businesses and institutions handling large document repositories:
- Multilingual and multimodal processing: The model supports a wide range of languages, scripts and document layouts, making it useful for global organizations. Yang emphasized this capability, calling it a game-changer for multilingual document processing.
- Structured output and document hierarchy preservation: Unlike basic OCR models, Mistral OCR retains formatting elements such as headers, paragraphs, lists and tables, ensuring extracted text is more useful for downstream applications.
- Document-as-prompt and structured outputs: Users can extract specific content and format it in structured outputs, such as JSON or Markdown, enabling integration with other AI-driven workflows.
- Self-hosting option: Organizations with stringent data security and compliance requirements can deploy Mistral OCR within their own infrastructure.
The Mistral AI developer documentation online also highlights document understanding capabilities that go beyond OCR. Mistral OCR allows users to interact with the document content by using natural language queries after extracting text and structure. This feature enables:
- Question answering about specific document content;
- Automated information extraction and summarization;
- Comparative analysis across multiple documents;
- Context-aware responses that consider the full document.
