+# Gemma-3-Gaia-PT-BR-4b-it-GGUF
+
+This model was converted to GGUF format from [CEIA-UFG/Gemma-3-Gaia-PT-BR-4b-it](https://huggingface.co/CEIA-UFG/Gemma-3-Gaia-PT-BR-4b-it) using llama.cpp.
+
+## About GAIA
+
+**GAIA** is an open, state-of-the-art language model for Brazilian Portuguese. It was developed by continuously pre-training the google/gemma-3-4b-pt model on an extensive, high-quality corpus of Portuguese data. The goal of GAIA is to democratize access to cutting-edge AI technology in Brazil.
