• Luminous / Various parameters / 5 EU languages / Semantic representation, embeddings / Commercial/API
• Pharia-1-LLM-7B-Control / 7B / German, French, Spanish / Open-source, multilingual corpus / Open Aleph License

Strengths: Emphasis on explainable and secure AI pipelines; EU AI Act compliance, data sovereignty, and support for public sector applications; Open Aleph License supports non-commercial/educational use with full transparency.

Velvet AI (Italy – Almawave)

Developed by Almawave and trained on the Leonardo supercomputer, Velvet models emphasize sustainability, multilingual reach, and broad industry application.

Technical Specifications (2025):

• Velvet-14B / 14B parameters / 128k tokens / IT, DE, ES, FR, PT, EN / Trained on 4T+ tokens / Apache 2.0
• Velvet-2B / 2B parameters / 32k tokens / IT, EN / Efficient, smaller size / Apache 2.0

Strengths: Eco-friendly architecture, broad European language coverage; optimized for healthcare, finance, and public administration; open-source and transparency ethos.

Minerva (Italy)

Italy’s first LLM family built on Italian language data, Minerva is a collaborative product by Sapienza NLP, FAIR, and CINECA.

Notable Model:

• Minerva 7B / 7.4B parameters / 2.5T training tokens / IT/EN / 50/50 data balance; instruction-tuned / Open-source

Strengths: Designed for Italian and English linguistic performance; transparent, open training data; instruction tuning for safer outputs.

EuroLLM-9B (EU)

A pan-European initiative supporting all 24 official EU languages, including 11 more, and released in both base and instruct forms.

Model Overview:

• EuroLLM-9B / 9B parameters / 35 languages covered (24 EU + 11 extra) / 4T+ training tokens / Open-source
• EuroLLM-1.7B / 1.7B parameters / 35 languages / Multilingual / Open-source

Strengths: Unmatched open multilingual coverage; outperforms similar-size open models in translation and reasoning benchmarks; synthetic datasets, EuroFilter technology for balancing languages.

LightOn (France)

Paris-based LightOn offers enterprise-grade, on-premises, privacy-focused generative AI. In 2024, it became Europe’s first generative AI startup to IPO.

Model Summary:

• Pagnol, RITA, Mambaoutai / General-purpose / Open-source
• Reason-ModernColBERT / Reasoning / Domain-specific
• BioClinical ModernBERT / Biomedical / Domain-specific

Strengths: Supports fully private, on-prem deployment; integrates domain specialization and optical computing research.

Comparison Table

Conclusion: Europe’s AI advances in 2025 reflect an environment focused on openness, sustainability, multilingual support, and compliance. Mistral leads with agile, performant models; Aleph Alpha pioneers explainability and data sovereignty; Italy’s Minerva and Velvet address national language and sustainable training; EuroLLM sets the bar for inclusivity; and LightOn delivers enterprise-grade privacy solutions.

These collective efforts position Europe as an increasingly influential player in global AI, particularly in the realms of multilingualism, ethical innovation, and technical openness.
