GitHub - zai-org/GLM-OCR: GLM-OCR: Accurate × Fast × Comprehensive

Imagine working in a company that handles a vast amount of different types of documents: contracts, invoices, financial reports. Every day, your team must extract crucial information from these documents to make informed decisions. However, documents arrive in various formats and often of low quality, making the manual extraction process slow and error-prone. One day, you receive a faxed document with a fraudulent transaction that needs to be identified and resolved urgently. How can you ensure that all information is extracted correctly and quickly?

GLM-OCR is the solution that solves this problem in an innovative way. This multimodal OCR model is designed to understand complex documents, offering unprecedented accuracy and impressive processing speed. Thanks to its advanced architecture, GLM-OCR can handle any type of document, from legal contracts to financial reports, ensuring that all relevant information is extracted correctly and in real-time. With GLM-OCR, your team can focus on what really matters: making informed decisions and resolving urgent problems without wasting time on manual and error-prone processes.

What It Does
#

GLM-OCR is a multimodal OCR model designed for understanding complex documents. It uses the GLM-V encoder-decoder architecture and introduces advanced techniques such as Multi-Token Prediction (MTP) loss and full-task stable reinforcement. In simple terms, GLM-OCR is like a virtual assistant that can read and understand any type of document, extracting crucial information with impressive accuracy.

The main features of GLM-OCR include the ability to handle complex documents such as tables, codes, stamps, and other difficult-to-interpret elements. Thanks to its advanced architecture, GLM-OCR can be easily integrated into various business workflows, offering a simple and intuitive user experience. You don’t need to be a technology expert to use GLM-OCR: the model is completely open-source and comes with a complete SDK and a chain of inference tools, making installation and use extremely simple.

Why It’s Amazing
#

The “wow” factor of GLM-OCR lies in its ability to combine accuracy, speed, and ease of use in a single package. It’s not just a simple linear OCR model: it’s an intelligent system that can adapt to a wide range of real-world scenarios.

Dynamic and contextual: GLM-OCR is designed to be dynamic and contextual. It can adapt to different types of documents and contexts, ensuring that the extracted information is always relevant and accurate. For example, if you are working with a legal contract, GLM-OCR can identify and extract specific clauses, dates, and signatures, making the review process much more efficient. “Hello, I am your system. The document you uploaded is a legal contract. I have extracted the following key clauses:…”.

Real-time reasoning: Thanks to its advanced architecture, GLM-OCR can process documents in real-time, providing immediate results. This is particularly useful in scenarios where quick decisions need to be made, such as in the case of a fraudulent transaction. “Hello, I am your system. I have detected a suspicious transaction in the document you uploaded. Here are the details:…”.

Operational efficiency: With only 0.9 billion parameters, GLM-OCR is extremely efficient in terms of computational resources. This means it can be easily integrated into existing systems without requiring advanced hardware. “Hello, I am your system. I processed the document in a few seconds, using minimal resources. Here are the results:…”.

Ease of use: GLM-OCR is designed to be easy to use, even for those without technical experience. Installation is simple and use is intuitive, thanks to a well-documented chain of inference tools. “Hello, I am your system. To get started, just follow these simple steps:…”.
