About prefeitura-rio/Rio-3.0-Open-Mini

Rio 3.0 Open Mini is a frontier-class reasoning model developed by IplanRIO, the municipal IT company of Rio de Janeiro's city government. Built through distillation on top of Qwen3-4B-Thinking-2507 using reasoning traces from our to be announced Rio 3.0 model, Rio 3.0 Open achieves state-of-the-art results across mathematics, STEM, and code benchmarks — surpassing its base model by significant margins and competing with models far larger than itself.
