In short:
- Mistral OCR 4.1 entered general preview on July 23, 2026, and became fully available on August 31, 2026.
- It adds block-level confidence scoring and more precise paragraph bounding boxes.
- It supports 170 languages and can run on your own server in a single container.
- Plain OCR costs $4 per thousand pages, dropping to half price in batch processing.
What is Mistral OCR 4.1?
This model is a document intelligence service that converts documents into Markdown and structured metadata. It processes PDFs, office files, and images page by page, extracting text, table, and image information (therundown.ai). It's offered in the Mistral Premier tier under the model ID mistral-ocr-4-1 (kompozy.io). Those with API access can also reach this model via the mistral-ocr-latest alias.
This approach differs from classic OCR tools. It doesn't just recognize letters — it also understands the document's structure. It preserves the position of paragraphs, tables, and images within the document.
How different is it from 4.0?
This update builds on the paragraph bounding boxes and structural block tags introduced in the previous version. The biggest innovation is block-level confidence scoring (docs.mistral.ai). This allows the reliability of each text block to be measured individually.
This detail is critical for enterprise use. If the confidence score for an amount field on an invoice is low, the system can automatically flag it for human review. This reduces the risk of faulty data processing.
This model's output returns bounding boxes, structural tags, tables, images, and confidence scores all together (docs.mistral.ai). This rich output makes it easier for developers to integrate document data directly into their workflows.
What do the performance scores show?
Mistral states that human evaluators preferred OCR 4 over its competitors on more than 600 real-world documents. The average win rate stands at 72 percent (mistral.ai). This rate shows that the model delivers consistent results on real-world documents as well.
It leads with a score of 85.20 on the OlmOCRBench test. On OmniDocBench, it reaches a score of 93.07 (mistral.ai). These two benchmarks measure accuracy across different document types.
The scores above show that the model is strong at parsing document structure. In particular, the high score on OmniDocBench points to consistency even with complex, densely formatted documents.
How does the pricing model work?
Plain OCR usage costs $4 per thousand pages. For annotated pages, this fee rises to $5 per thousand (qwe.edu.pl). In batch processing mode, the price is cut in half, with a thousand pages processed for $2.
This pricing offers a significant advantage for organizations handling large volumes of documents. Batch mode is a practical way to lower costs for non-urgent jobs. Businesses can manage their daily invoice or contract flow with this model at a favorable cost.
What workflows is it suited for?
This tool is designed for RAG data ingestion, enterprise search, invoice processing, compliance checks, redaction, and citation workflows (therundown.ai). These use cases cover the needs of both software teams and operations units.
Broad language support provides significant flexibility for international companies (mistral.ai). Documents from different countries can be processed with a single system.
The model can also be self-hosted on your own servers thanks to its single-container setup (mistral.ai). This feature makes it a preferred choice for organizations that prioritize data privacy. In enterprise software projects, these kinds of flexible deployment options ease the integration process.

Can it be run on your own server?
Yes, this model offers a self-hosted deployment option. The single-container architecture simplifies setup (mistral.ai). This approach matters for teams looking to reduce cloud dependency.
The self-hosting option is especially favored in sectors that handle sensitive data. In fields like healthcare, finance, and law, data sovereignty is a critical issue.
Frequently asked questions
What is the difference between Mistral OCR 4.1 and OCR 4.0?
4.1 builds on the paragraph bounding boxes and block tags found in 4.0. The main innovation is the addition of block-level confidence scoring, delivering more precise results.
How much does it cost and how does the payment model work?
Plain OCR costs $4 per thousand pages, and $5 for annotated pages. In batch processing, the price is cut in half, dropping to $2 per thousand pages.
Which languages does it support?
This model supports a total of 170 languages. This broad coverage allows multinational companies to process documents from different markets with a single system.
What applications is it ideal for?
It's suited for RAG data ingestion, enterprise search, invoice processing, compliance checks, redaction, and citation workflows. Thanks to its structured output, these processes can be automated.
Can I host it on my own server?
Yes, the model can run on your own infrastructure thanks to its single-container operation. This offers a practical solution for organizations with data privacy requirements.
This technology brings the power of artificial intelligence to businesses in document processing workflows. With the right integration, invoice, contract, and archive management move forward much faster. At EngerekTech, we're here to adapt these kinds of AI-powered solutions to your business processes.
