🤖 Release of the Rio 3.5 Open 397B Multimodal Model
The Rio de Janeiro Administration has released Rio 3.5 Open 397B — a large multimodal model created by merging Nex-N2-Pro and Qwen3.5-397B-A17B followed by distillation. The model features a context window of up to 1,010,000 tokens and has approximately 397 billion parameters (with ~17 billion active).
🌍 The emergence of a powerful open model with a massive context window and an efficient MoE architecture intensifies competition with proprietary solutions. The distillation method used to improve the base Qwen models confirms the effectiveness of knowledge transfer.
👤 High-performance, GPT-4/5 level models can now be used in projects for free and locally, processing massive amounts of text — such as entire books or codebases — in a single pass.
