The Rio 3.5 model broke the internet this week. The plot twist? It’s essentially our open-source model, Nex N2 Pro, wearing a different hat. 🤯 We analyzed the weights, and the recipe is exact: Rio 3.5 ≈ 0.6 * Nex N2 Pro 0.4 * Qwen 3.5 It even literally introduces itself as "Nex N2 Pro" if you ask it without initial system prompt! 😂 We are flattered that the City of Rio used our work to achieve SOTA performance. Thanks for the ultimate benchmark validation. 🤝 But in the open-source world, attribution matters. 👇 Full mathematical proof & verify script in the first reply!

🇧🇷 Modelo de IA aberta treinada no Rio com financiamento público ao longo do último ano pela @Prefeitura_Rio superando todos os outros modelos. Inteligência artificial não é uma coisa distante, estrangeira, de laboratório bilionário…não existe só pra fazer texto, imagens aleatórias. O Rio acaba de disponibilizar um modelo aberto de inteligência artificial. E o que isso significa? Capacidade de analisar mais dados, responder mais rápido, entender problemas complexos sem depender de soluções compradas prontas lá fora. E com a Pref.rio interagir e atender melhor a população usando IA. Significa pra quem ainda tinha alguma dúvida sobre o potencial do “Rio AI City” agora vai precisar olhar pra cá com muita atenção e seriedade. Energia, água em abundância, conectividade, talentos, construção de data centers e visão de futuro. Hoje o mundo está falando de um modelo aberto de IA treinado no Rio. Engenharia brasileira. Soberania. Desenvolvimento tecnológico. Rio no centro do futuro. Parabéns ao time da @Prefeitura_Rio com o IPLAN mostrando ao Brasil que é possível! Obrigado @eduardopaes por ter acreditado e iniciado o desenvolvimento desse projeto no último ano. Seguimos! - 🇧🇷 An open AI model trained in Rio and publicly funded over the last year by @Prefeitura_Rio has just surpassed all other models. Artificial intelligence is not something distant, foreign, or confined to billion-dollar labs. It is not just about generating text or random images. Rio has just made an open artificial intelligence model publicly available. And what does that mean? It means greater capacity to analyze data, respond faster, and understand complex challenges without depending on off-the-shelf solutions developed abroad. It means @Prefeitura_Rio will be able to interact with and serve people better through AI. For anyone who still had doubts about the potential of “Rio AI City,” it’s time to pay close attention. Clean energy, abundant water, connectivity, data center development, talents and a long-term vision for the future. Today, the world is talking about an open AI model trained in Rio. Brazilian engineering. Sovereignty. Technological development. Rio at the center of the future. Congratulations to the entire @Prefeitura_Rio team, especially IPLAN, for showing Brazil that this is possible. And thank you @eduardopaes for believing in and launching this project last year. We keep moving forward. 🇧🇷
