## About Solar
Solar Pro is a cutting-edge large language model (LLM) developed by Upstage, designed to deliver high-performance natural language processing capabilities while operating efficiently on a single GPU. With 22 billion parameters, it matches the performance of larger models, such as those with 70 billion parameters, but with significantly reduced computational requirements. This efficiency is achieved through Upstage's proprietary Depth-Up Scaling (DUS) method and advanced data processing techniques. Solar Pro excels in understanding structured text formats like HTML and Markdown, making it particularly adept at handling complex enterprise data. Additionally, it demonstrates superior multilingual proficiency, with notable improvements in Korean and Japanese language benchmarks, alongside consistent excellence in English. These capabilities position Solar Pro as an ideal solution for industries requiring advanced language understanding and processing, including finance, healthcare, and legal sectors.
