S-OWMI: A Perimeter Auditing Framework for Open-Weight Models in Latin American Institutions

We propose the Spanish Open-Weight Maturity Index (S-OWMI), an auditable perimeter-evaluation framework for open-weight LLMs deployed by Latin American institutions that need data sovereignty and regulatory compliance. We evaluate Llama-3.1-8B and Qwen2.5-7B on a Spanish-diverse dataset against an English baseline.

With Mauricio Genta, Federico Hörl and Nicolás Adrián Oroz
