On Tuesday,?? ?? four-month-old AI startup Baichuan Intelligent Technology unveiled its first closed-source model equipped with 53 billion parameters. Following the Chinese company’s rapid release of two open-source large language models since its founding in April, the new model demonstrates the firm’s fast pace in delivering pre-trained models for larger parameters. The freshly introduced model, Baichuan-53B, is mainly for corporate clients and focused on text generation. A ChatGPT-like chat service built on the model entered internal testing on the same day the model was launched, its official website shows, with plans for the firm to publicly launch APIs and associated components next month.
