📚 Overview

Despite recent advances in open Large Language Models (LLMs), European Portuguese (pt-PT) remains underrepresented in both training data and evaluation benchmarks. Existing evaluations often rely on machine-translated datasets, which fail to capture important linguistic and cultural nuances of the language.

AMALIA addresses this gap by:

• Prioritizing high-quality pt-PT data during all training stages
• Providing a fully open LLM tailored specifically for European Portuguese
• Introducing new evaluation benchmarks for pt-PT

Experimental results show that AMALIA remains competitive with strong baselines, while achieving substantial improvements on pt-PT-specific evaluations, highlighting the importance of targeted training and native benchmarking for underrepresented language variants.
