In this study, we show that a modest amount of in-domain training brings significant improvements in few-shot tasks. Our best model, Sabiá-65B, outperforms ChatGPT-3.5 on average in 14 Portuguese tasks. The work has been published in the BRACIS 2023 conference.

The Sabiá-7B model is available on Hugging Face

In this technical report, we introduce the new generation of Maritaca models, Sabiá-2, and present the most complete analysis of current LLMs in Portuguese tasks, covering 64 brazilian exams.

Our best model, Sabiá-2 Medium, greatly outperforms several competitor LLMs in the same price range.

Juru is the first LLM trained in Brazilian legal data. In this study, we show that training Sabiá-2 Small on law-related documents from reliable websites, such as the CNPQ library, brings gains in Enade and OAB law tests.


In this study, we evaluated GPT-3.5 and GPT-4 on the ENEM and showed that using the Chain-of-Thought technique significantly improves GPT-4's performance.

BLUEX is a dataset composed of entrance exams from two of Brazil's leading universities: USP and UNICAMP. Its main purpose is to serve as a reference for the evaluation of current and future AI models, including those with multimodal capabilities (image+text). The work has been published in the BRACIS 2023 conference.
