Latvian AI company Tilde enters the global AI race with a European multilingual model and safeguards against disinformation

RIGA, Latvia, Oct. 15, 2025 (GLOBE NEWSWIRE) -- Latvian AI company Tilde has unveiled TildeOpen LLM, an open-source large language model trained on Europe’s flagship supercomputer LUMI. With 30 billion parameters, TildeOpen outperforms global rivals in European languages and adds safeguards against Russian disinformation.

Developed by a 12-person team at Tilde Research Lab, TildeOpen rivals Big Tech at a fraction of the cost. The model excels in both major and smaller European languages often neglected by global models.

Most commercial AI models are trained mainly on English, producing weak results for smaller European languages and leaving over 200 million Europeans underserved. TildeOpen fills this gap by covering 34 languages, including 24 official EU languages plus Ukrainian, Norwegian, Icelandic, Turkish, and Balkan languages.

In public benchmarks, TildeOpen-30B sets a new state of the art on the Belebele reading comprehension benchmark, with an average accuracy of 84.7%, outperforming open models such as Gemma-27B, ALIA-40B, and EuroLLM-22B.

Safeguarding European AI from disinformation

TildeOpen filters disinformation and propaganda, protecting the model from hostile influences. Research shows Russian state-aligned networks have inserted disinformation into global AI models. To counter this, Tilde worked with media monitoring authorities and used topic modeling to block sensitive material from Kremlin-controlled sources.

Unlike global models hosted abroad, TildeOpen can be deployed locally or in trusted European clouds, ensuring compliance with EU data protection standards, the AI Act, and the upcoming General-Purpose AI Code of Practice.

Delivering on Europe’s AI innovation promise

TildeOpen is among the first outcomes of the European Commission’s initiative to unleash Europe’s supercomputing power for AI startups. The Large AI Grand Challenge awarded Tilde €250,000 in funding and 2 million GPU hours on LUMI.

“For Europe to be truly sovereign in AI, we must move beyond dependence on English-centric models built elsewhere. TildeOpen proves Europe can create world-class foundation models that are secure, multilingual, and built for our linguistic diversity,” said Artūrs Vasiļevskis, CEO of Tilde.

Open and available to all

TildeOpen is released on Hugging Face (TildeAI/TildeOpen-30b) under a CC-BY-4.0 license, allowing full flexibility for researchers, universities, startups, public administrations, and companies.
