Maritaca AI builds large language models specialized in Portuguese and Brazilian contexts to handle complex local legal, educational, and institutional tasks.

Founded by researchers from Unicamp, Maritaca AI develops the Sabiá model family: proprietary LLMs engineered specifically for the nuances of the Portuguese language and Brazilian regulatory landscapes. Their flagship Sabiá 4 model handles long-document analysis up to 128,000 tokens and excels at domain-specific benchmarks, scoring 87% on the Brazilian Bar Exam (OAB) and 91% on the National Civil Service Exam (CPNU). By offering both an intuitive web chat interface and a developer API, the platform provides local enterprises and developers with a high-performance, cost-effective alternative to generalized global models.
