New model on huggingface

The "Rio-3.5-Open-397B" model has been released on Hugging Face, representing a fine-tuning of the Qwen architecture. This model boasts open weights, providing accessibility for practitioners, and is noted to perform comparably to Qwen 3.7 plus. The open availability of such a large model (397 billion parameters) is significant for developers seeking to leverage advanced capabilities in LLM applications without the constraints of proprietary models.
