Our Goal:
To bring the best of cutting edge AI to all of Brazil's citizens.
Today's AI landscape is dominated by models that think in English and only localize their answers into Portuguese—leaving the reasoning trace outside our language and constraining Brazil's digital sovereignty and potential.
We're changing that.
Localized Reasoning.
Reasoning models represent a fundamental leap forward from traditional AI, moving from simple pattern matching to genuine understanding and problem-solving. They don't just process language; they comprehend context, causality, and logic, enabling them to tackle complex, multi-step tasks that are impossible for non-reasoning models.
Deep Understanding
Our reasoning AI grasps the underlying logic and intent behind every query.
Complex Problem-Solving
The system evaluates strategies, plans steps, and synthesizes insights for coherent outcomes.
Enhanced Accuracy and Reliability
By reasoning through each challenge, the model minimizes hallucinations and validates information.
True Adaptability
Continuous reasoning about new data allows the model to adjust to novel contexts in real time.
Industry-leading reasoningin Brazilian Portuguese
Our composite benchmark uses common Brazilian Portuguese benchmarks focused on academic performance such as university entrance exams (ENEM, BlueX, OAB exams), datasets widely adopted by the Brazilian natural language processing community (ASSIN 2 STS, ASSIN 2 RTE), as well as very important and less-frequently sampled data sets (FaQUaD-NLI, HateBR) and social datasets (tweetsentBR, PT Hate Speech).
The Reasoning Advantage
Here's how our native language reasoning model delivers superior performance:
The Highest Portuguese Performance
Better Portuguese accuracy, fewer production mistakes, less context rot and fewer tokens needed. Far better performance in search and retrieval tasks. Fewer failure modes from language shifts and lower cumulative latency. Lower latency from Brazilian hosting allows for more real-time applications for Brazilians.
Thinks in Portuguese, Not English, Understands Brazilian Context
Understands Brazilian cultural nuance, idioms, and implicit context that don't translate to other models' native languages. Reasons correctly about Brazilian legal system, tax codes, and regulations (e.g., Lei Geral de Proteção de Dados, Sistema Tributário Nacional).
Lower Cost, Better Stewardship
Dramatically lower cost per token, token use, and compute requirements lowering total cost of ownership. Greater energy efficiency for training and inference conserves natural resources. Brazilian electricity is ~90% renewable, among the cleanest in the world.
Protects National Sovereignty
Higher trust and adoption by Brazilian users and regulators due to performance and explainability. Fit for public and regulated sectors. Ensures full and unambiguous compliance with the LGPD and data residency. Mitigation of inherent algorithmic and cultural biases. Protects access to critical technology from foreign intervention.
Safety
A native Portuguese reasoning model provides something systems that reason in English fundamentally cannot: reasoning traces auditable in Portuguese at every step.
