Solar Open Solar Open is Upstage's flagship 102B parameter large language model, trained entirely from scratch and released under the Upstage Solar License (see LICENSE for details). As a Mixture of Experts (MoE) architecture, it delivers enterprise grade performance in reasoning, instruction following, and agentic capabilities—all while prioritizing transparency and customization for the open source community. Technical Report Project Page Highlights 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 .
