📊 Full opportunity report: ALIA. The Spanish answer. on ThorstenMeyerAI.com — validation score, market gap, and execution plan.
TL;DR
Spain’s ALIA-40B, a €240 million public AI project, has released an open-source multilingual model trained on 35 languages. While its performance is below Llama 2 benchmarks, it emphasizes Spanish-language adoption and operational transparency, marking Spain’s largest national AI effort to date.
Spain’s ALIA project has officially released ALIA-40B, a 40-billion-parameter multilingual language model trained on 9.37 trillion tokens across 35 European languages, marking the country’s largest public AI initiative to date.
The project, coordinated by the Barcelona Supercomputing Center (BSC-CNS) and led by the Secretary of State for Digitalisation and Artificial Intelligence (SEDIA), was funded with over €240 million from public sources, including €90 million for MareNostrum 5 upgrades and €150 million dedicated to ALIA integration into industry.
ALIA-40B was trained from scratch on a dataset of 12.875 trillion tokens, with a focus on multilingual coverage and Spanish-language oversampling. It was released under the Apache License 2.0 on HuggingFace on April 22, 2025, and has undergone validation by AESIA, Spain’s AI security authority.
Benchmark results show ALIA-40B’s performance below Llama 2, with 51.77% accuracy on XNLI (English) versus Llama 2’s 66%, and 81.53% on SQuAD (English) versus Llama 2’s 93-94%. These results confirm a structural capability gap, aligning with prior empirical findings about the model’s operational limits.
ALIA.
The Spanish
answer.
€240M+ Spanish public funding · ALIA-40B + Salamandra family · 9.37T tokens · 35 European languages + 92 programming languages · MareNostrum 5 · Apache 2.0 release. The largest publicly funded European national-AI project by cumulative scope — and the empirical test case for the Position 1 vs Position 3 strategic-positioning argument.
This is the tenth standalone essay in the European sovereign-LLM track and the third Tier 2 expansion piece. ALIA is Spain’s institutional answer — the largest EU member state by GDP not yet documented in the track. The project markets itself as Position 1 + Position 2 simultaneously — “Europe’s first public multilingual foundational model.” The benchmark evidence (ALIA-40B 51.77% XNLI_en vs Llama 2 66%) confirms the structural capability gap from Finding 1 of the synthesis essay. The Position 3 framing — Martorell’s “most widely adopted in the Spanish-speaking world” — is operationally honest. €90M MareNostrum 5 upgrade + €150M company integration = €240M+ cumulative scope. Apache 2.0 open-source release + AESIA validation + co-official languages oversampling. Both can be true at once. The Spanish public discourse would benefit from explicit Position 3 strategic positioning.
Six models. Apache 2.0.
The ALIA family operates as a tiered model portfolio. ALIA-40B is the flagship at 40 billion parameters; the Salamandra family scales down to 7B, 2B and instruct-tuned variants; mRoBERTa provides the foundational multilingual baseline. All released under Apache License 2.0 on April 22, 2025 at the HispanIA 2040 event — “Public Code, Public Money” approach.

Four official. Oversampled by factor of 2.
ALIA’s distinctive multilingual coverage strategy. The four co-official Spanish languages are oversampled by factor of 2 in the training corpus — structurally distinct from Apertus’s broad 1,811-language coverage approach. The strategy targets deep coverage of Spanish co-official languages rather than maximum language breadth.

ALIA-40B vs Llama 2. 14-point gap.
The empirical evidence Finding 1 of the synthesis essay needed. ALIA-40B at 40 billion parameters with €240M+ public funding and 8+ months MareNostrum 5 training achieves performance below Llama 2 — a 2023 frontier model released approximately 18 months before ALIA-40B. The capability gap is real and consistent with six of seven prior national-project answers documented in the track.

Two pilots. Public administration deployment.
The operational deployment targets that validate the Position 3 + Position 4 framing. Public administration deployment is the structurally credible Position 3 + Position 4 strategic positioning — captive demand from Spanish public institutions where Spanish-language specialization is operationally distinctive.
The work is real across the Spanish ALIA case. €240M+ public funding committed. 40B parameter from-scratch model trained on 9.37 trillion tokens. Salamandra family released under Apache 2.0. AESIA validation aligned with EU AI Act transparency standards. Two pilot applications shipped — Tax Agency chatbot and primary care medicine heart failure diagnosis. The Position 1 framing is operationally misleading. ALIA-40B performance below Llama 2 confirms the structural capability gap. The Position 3 framing is operationally honest — Spanish-speaking world adoption, co-official languages oversampling, public administration deployment. Both can be true at once. The Spanish public discourse would benefit from explicit Position 3 strategic positioning.

Implications of ALIA-40B’s Performance and Strategy
While ALIA-40B’s benchmarks are below those of Llama 2, the project’s emphasis on Spanish-language adoption and open-source transparency positions it as a strategic national asset for Spain and the broader European multilingual AI landscape. The focus on co-official languages and AESIA validation underscores a commitment to operational honesty and regional relevance, even as performance metrics highlight a capability gap compared to larger models.
This effort exemplifies a broader European approach to developing sovereign AI, balancing performance with multilingual coverage, transparency, and public funding. It signals Spain’s intent to foster widespread adoption of AI tools in government, industry, and academia, particularly within the Spanish-speaking world.

Background on Spain’s National AI Initiative
Spain’s ALIA project is part of a broader national AI strategy launched in early 2025, with €240 million in public funding and coordination led by the Barcelona Supercomputing Center. It follows a series of European and national AI projects, including Portugal’s AMÁLIA, Italy’s Minerva, and the pan-European OpenEuroLLM, each with varying scopes and funding levels.
Prior efforts have demonstrated the challenges of scaling and benchmarking large language models, with performance often below industry leaders like Llama 2. ALIA’s focus on multilingual coverage, especially Spanish, reflects Spain’s strategic aim to foster regional AI sovereignty and adoption.
The project also aligns with the European Union’s push for sovereign AI infrastructure, leveraging MareNostrum 5’s high-performance computing capabilities and emphasizing open-source deployment and transparency. Explore the policy landscape for AI development.
“Our goal is not to be the best in terms of raw performance but to create a model that is widely adopted across the Spanish-speaking world.”
— Josep M. Martorell, ALIA project lead
Operational Performance Compared to Global Leaders
While benchmark results confirm a capability gap between ALIA-40B and larger models like Llama 2, it remains unclear how this gap will evolve with further training, fine-tuning, or future model iterations. The real-world impact of its multilingual capabilities and adoption rate also remains to be seen, as operational metrics beyond benchmarks are still emerging.
Next Steps for ALIA Model Deployment and Evaluation
Spain’s authorities plan to monitor ALIA-40B’s adoption across government and industry sectors, with ongoing benchmarking and fine-tuning to improve performance. Further validation and transparency reports are expected in the coming months, alongside efforts to expand multilingual capabilities and real-world application testing.
Additionally, the project aims to foster a regional ecosystem of Spanish-language AI tools, with potential collaborations across European institutions and private sector partners to enhance model capabilities and deployment strategies.
