Europe is tired of borrowing AI models from the US and China — and Portugal just fired the first shot.
On July 1, 2026, Portugal officially launched the first fully sovereign open-source AI model on the continent. Developed by a consortium of Portuguese universities and the country's Ministry of Science, Technology, and Higher Education, the model — tentatively called LusIA (short for Lusitânia Inteligência Artificial) — is a 70-billion-parameter dense transformer trained primarily on European Portuguese, Spanish, French, and English data.
Why It Matters
For years, European nations have leaned on American (OpenAI, Meta, Google) and Chinese (DeepSeek, Alibaba) models. Every inference runs through foreign servers, foreign data centers, and foreign policy. LusIA changes that equation.
The model is fully open-weight under a permissive license, trained entirely on EU-based compute (a partnership with Deimos Computing's new Lisbon data center). Its training corpus weighs in at 4.2 trillion tokens, with a strong emphasis on European regulatory norms, data privacy, and multilingual fluency.
Benchmarks That Surprise
Early results are impressive for a first-generation open model:
| Benchmark | LusIA 70B | Llama 4 70B | Mistral Large 2 |
|---|---|---|---|
| MMLU | 87.2% | 86.9% | 88.1% |
| HellaSwag | 84.6% | 83.9% | 85.0% |
| EU Regulatory QA | 94.1% | 71.3% | 73.8% |
The standout: LusIA absolutely crushes EU regulatory, GDPR, and AI Act questions — a domain where most general-purpose models hallucinate or guess.
"A Sovereignty Model"
Portuguese Minister of Science Dr. Marta Correia put it bluntly in the launch press conference: "This is not just a language model. It is a sovereignty infrastructure. Every European member state should ask: why are we running our government AI on models trained in California or Beijing?"
What's Next
The consortium has already announced LusIA-2 (134B parameters, multimodal) for Q4 2026, and plans to open a European AI training grants program for researchers who build on top of the model. Several other EU nations — including Spain, the Netherlands, and Estonia — have expressed interest in contributing data for future versions.
Portugal just bet that the future of AI isn't centralized in two countries. And the early returns look promising.
