 * **MoE Architecture (102B / 12B):** Built on a Mixture-of-Experts architecture with **102B total / 12B active parameters**. This design delivers the knowledge depth of a massive model with the inference speed and cost-efficiency of a much smaller model.
 * **Massive Training Scale:** Pre-trained on **19.7 trillion tokens**, ensuring broad knowledge coverage and robust reasoning capabilities across various domains.
+* **Quantized Version Available:** An official INT4 quantized model is provided by NotaAI and available at [`nota-ai/Solar-Open-100B-NotaMoEQuant-Int4`](https://huggingface.co/nota-ai/Solar-Open-100B-NotaMoEQuant-Int4).
