Vietnam’s new AI model masters complex document analysis
CATI-VLM is an AI model for document reading that has already claimed a spot among the world’s elite, ranking first in Vietnam and among the top 12 globally in the Document Visual Question Answering (DocVQA) category of the Robust Reading Competition (RRC) in June 2025.

Hanoi (VNA) – As Vietnam races to embrace digital transformation and artificial intelligence (AI), a homegrown innovation is poised to redefine how users haﷺndle the country’s complex language and documents.
The CMC Research Institute for Applied Technology (CMC ATI) has unveiled CATI-VLM, an AI model for document reading that has already claimed a spot among the world’s elite, ranking first in Vietnam and among the top 12 globally in the Document Visual Question Answering (DocVQA) category of the Robust Reading Competition (RRC) in June 2025.
The RRC, launched in 2011 by the Computer Vision Centre at the Autonomous University of Barcelona, is a prestigious global stage for advancements in computer vision and document recognition. It has attracted heavyweights like Tsinghua University, Hyundai Motor Group, and Tencent. Held alongside the International Conference on Document Analysis and Recognition, it tests the ability of AI to interpret intricate documents, which is a critical need in Vietnam, where the language’s diacritics and handwritten texts pose unique challenges.
Unlike traditional optical character recognition systems that merely extract text, CATI-VLM goes deeper, analysing not just words but also checkboxes, charts, signatures, formulas, and document layouts.
Trained on a sprawling 5-terabyte dataset, the model can answer questions posed on document images, much like conversational AI tools such as ChatGPT, without requiring prior training on specific formats. Its versatility makes it a powerful tool for digitising documents, automating business processes, and strengthening governance.
Remarkably, CATI-VLM achieves this with just 3 billion parameters, a fraction of the size of competitors like Deepseek (27 billion parameters), GPT-4 Vision Turbo paired with Amazon Textract OCR (Top 34), and Baidu (Top 22). Yet it topped four of the seven RRC benchmark datasets, showcasing a balance of efficiency and accuracy tailored to Vietnam’s computing infrastructure.
Nguyen Trung Chinh, Chairman and Executive President of CMC Corporation, attributed the breakthrough to over a decade of research investment and a commitment to developing Vietnamese-origin technologies. “This milestone aligns with our vision for AI-driven transformation and global expansion,” he said.
Looking ahead, CMC plans to embed CATI-VLM into its C.OpenAI ecosystem, powering tools like CLS – a legal document auditing assistant, SmartDoc – a platform for digital document transformation, and CMC KMS – a knowledge management system. The model will also drive automated reporting and next-generation document applications./.
General Secretary Lam also emphasised the need to immediately issue policies to attract and retain high-level domestic and overseas talents, particularly in critical fields like AI, semiconductors, and advanced materials.
The National Data Development Fund has been established, operating as a non-budget state financial fund with an initial capital of 1 trillion VND (38.4 billion USD).
Vietnamese businesses, particularly small and medium-sized enterprises (SMEs), must embrace digital and AI transformations to remain competitive and achieve sustainable growth, experts said.
VietNEST (Vietnamese Nurturing Education for Science & Traditions) is a mobile app and digital platform for Vietnamese language learning among overseas children.
The networks bring together universities, research institutes and domestic and foreign businesses. Members will work closely in training, research, and technology transfer by sharing curricula, improving faculty capacity, providing access to laboratories and research facilities, and jointly implementing science and technology projects.
The Better Choice Awards (BCA) 2025 is a key highlight in the lead-up to Vietnam Innovation Day that falls on October 1, an annual event expected to attract hundreds of innovative enterprises, research institutions, investment funds, and startups from both Vietnam and abroad.
The new line serves as a critical backup route, strategically complementing existing submarine cables and enhancing the resilience, proactivity, and security of Vietnam’s telecommunications infrastructure.
Vietnam is actively yet cautiously preparing for the construction of its first nuclear power plant in Ninh Thuan (now the south-central coastal province of Khanh Hoa). The resumption of the programme after years of suspension carries considerable significance for the nation’s development in a new era as it strives to gradually reduce and ultimately phase out coal-fired power to realise the Government’s commitment to Net Zero by 2050.
The government leader reaffirmed Vietnam’s goal of achieving self-reliance in the design, manufacturing, and test of necessary semiconductor chips by no later than 2027.
With the launching of its two-tier local administration model, the city is incorporating technologies such as artificial intelligence (AI) and blockchain to enhance service delivery for citizens and businesses, aligning with the Politburo’s Resolution 57-NQ/TW on breakthroughs in science, technology, innovation, and national digital transformation.
Vietnam has issued many key policies to support semiconductor development, notably the Politburo’s Resolution 57 on science, technology, innovation, and digital transformation. Other initiatives include the Semiconductor Industry Development Strategy to 2030, with a vision to 2050, and the Human Resources Development Programme for the Semiconductor Industry.
Vietnam is no longer just an emerging blockchain market, it is stepping into a leadership role, with global investors, developers, and experts recognising its growing potential to become a leading hub for digital assets in the region.
Taking place on August 1–2, the event features more than 20,000 attendees and over 200 speakers from Vietnam, the h Korea, Singapore, the UAE, Hong Kong (China) and the US.
Dung directed the Ministry of Science and Technology to revise the national startup scheme, ensuring it clearly defines the scope and content, grounded on strong political and legal foundations, international best practices, and well-reasoned arguments for submission to the Government.
The two-day academic forum, themed “Resilience, Sustainability & Digital Transformation in a Changing World: Perspectives from Southeast Asia”, aims to share interdisciplinary research insights, focusing on adaptive capacity, sustainable development, and digital transformation amid evolving global and regional landscapes.
With such a rapid economic growth, Vietnam must diversify energy sources and nuclear power is a rational choice to ensure the national energy security, said Associate Professor Kei Koga from the Nanyang Technological University (Singapore).
Deputy Prime Minister Nguyen Chi Dung emphasised that Vietnam has a clear strategy and ambition in this field, and is rapidly emerging as a central hub and key link in the regional and global semiconductor value chains.
According to Cushman & Wakefield’s latest Asia-Pacific Data Centre Investment Landscape report, Vietnam now ranks second in the region for data centre investment returns, with a yield on cost (YoC) of 17.5–18.8%, just behind Singapore’s 21–23%.
Vietnam is taking drastic yet cautious steps in building a culture of nuclear safety and security, with the aim of having its first nuclear power plant operational by the end of 2030 and using this specific energy source effectively and sustainably.
Vietnam’s 5G strategy has been clearly outlined in national digital technology and infrastructure policies. A wide range of solutions is being vigorously implemented to achieve the target of an average internet speed of 100 Mbps by 2025 and full nationwide 5G coverage by 2030.
The visit aimed to assess the new two-tier local government model, preparations for upcoming Party congresses at levels, and implementation of the Politburo’s Conclusion on school construction in border areas.
Under the theme “Breakthrough Era with the Development of Industrial Internet”, the event gathered over 400 delegates, including senior officials, leading Internet experts, and technology engineers from Vietnam and abroad.
