INSAIT: Driving the Future of Artificial Intelligence from Bulgaria
Located in Sofia, Bulgaria, the Institute for Computer Science, Artificial Intelligence and Technology (INSAIT) has rapidly emerged as a premier global hub for scientific innovation. Operating as a specialized unit within Sofia University "St. Kliment Ohridski," INSAIT is dedicated to conducting world-class research across the most critical frontiers of modern technology.
As of March 2026, the institute has achieved remarkable academic standing, ranking 14th in Europe according to CSRankings and holding the top position in Eastern Europe. Its excellence is particularly notable in computer vision, where it ranks 6th in Europe, alongside significant contributions to robotics, machine learning, natural language processing, and algorithms.

Key Facts
- Location: Sofia, Bulgaria.
- Founding: Established in February 2021; officially launched on 11 April 2022.
- Top Ranking: 1st in Eastern Europe and 14th in Europe (CSRankings).
- Core Research: Machine learning, computer vision, robotics, and quantum computing.

History and Foundation
The vision for INSAIT was first presented in April 2019 by its founder, Prof. Martin Vechev, who currently serves as the scientific director and chair of the supervisory board. The institute was formally established by a decree from the Bulgarian Council of Ministers in February 2021.
The creation of INSAIT is the result of a high-level international partnership involving the Government of Bulgaria, ETH Zurich, EPFL, and Sofia University "St. Kliment Ohridski." This collaboration was ratified by the Bulgarian Parliament in September 2021. To support its long-term mission, the Bulgarian government committed approximately EUR 85.1 million in funding over a ten-year period.
Beyond government support, INSAIT benefits from significant contributions from the technology sector. Major industry players including Google, Amazon Web Services, DeepMind, SiteGround, and VMware have provided support, alongside individual entrepreneurs through the INSAIT Research and Education Foundation.
Governance and International Collaboration
INSAIT is managed through a sophisticated governance structure designed to ensure scientific excellence. A Supervisory Board, composed of internationally recognized leaders such as Prof. Martin Vechev and Prof. Srdjan Capkun, oversees the institute's direction, while an Executive Director manages daily operations.
The institute's influence extends far beyond Bulgaria through several key international affiliations:
- ELLIS Unit: INSAIT hosts the first European Laboratory for Learning and Intelligent Systems (ELLIS) unit in Eastern Europe.
- MIT Partnership: In June 2025, a USD 1 million research exchange program was launched with the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL).
- AI Alliance: As a founding member, INSAIT is the first Eastern European organization involved in this global initiative for open and responsible AI development.
Cutting-Edge Research and Notable Releases
The institute focuses on a diverse array of technical disciplines, including Information Security and Cryptography, Quantum Computing, and Secure and Trustworthy AI. Its researchers consistently publish in premier venues such as NeurIPS, ICML, and CVPR.
Generative AI and Language Models
One of INSAIT's most significant achievements is the development of BgGPT. Launched in 2023, BgGPT is the first Bulgarian generative AI large language model (LLM). It is designed to handle conversational tasks in both Bulgarian and English. In March 2026, the institute released BgGPT 3.0, a multimodal version capable of processing text, image, and voice, which is considered a strategic asset for Bulgaria's technological sovereignty.
In a similar vein of regional support, INSAIT co-developed MamayLM, a high-efficiency Ukrainian LLM, in collaboration with ETH Zurich. This model utilizes advanced data mixing to ensure strong linguistic and cultural performance in Ukrainian.
Compliance and Infrastructure
Recognizing the importance of regulation, INSAIT, ETH Zurich, and LatticeFlow AI released COMPL-AI in October 2024. This is the first open-source, compliance-centered evaluation framework designed to align Generative AI models with the EU AI Act.
Furthermore, Bulgaria has been selected to host one of six new European AI factories. This €90 million project, a collaboration between INSAIT and Sofia Tech Park, will establish the BRAIN++ facility. This modern GPU AI data center will feature the Discoverer++ supercomputer, providing essential cloud-based resources for researchers and startups.
Commercial Spin-offs
INSAIT's research frequently translates into commercial innovation through spin-off companies:
- LogicStar AI: A deep-tech startup developed with ETH Zurich that provides an agentic AI platform for automated software maintenance and bug resolution.
- Martian Lawyers Club (MLC): A company focused on AI-powered game personalization, using generative AI to create interactive, player-tailored in-game dialogue.
