Meet Skywork-13B: A Family of Large Language Models (LLMs) Trained on a Corpus of Over 3.2T Tokens Drawn from both English and Chinese Texts

Bilingual LLMs have gotten more and more necessary in our interconnected world, the place language range is a typical problem. They’ve the potential to interrupt down language limitations, promote cross-cultural understanding, and enhance entry to info and providers for individuals who converse completely different languages. Bilingual LLMs can be utilized to offer high-quality machine translation providers. They’ll translate textual content from one language to a different, serving to break down language limitations and facilitate communication throughout completely different cultures and areas.

With the expansion within the want for these fashions, there’s a development within the development of commercialization and the necessity for extra transparency. Many organizations solely make the mannequin checkpoints publicly accessible and withhold the very important info of a mannequin. To regain transparency in AI, the researchers at Kunlun Expertise constructed a household of huge language fashions skilled on over 3.2 trillion tokens drawn from each English and Chinese language texts with a complete disclosure. It’s known as  Skywork – 13B.

Skywork-13B household consists of Skywork-13B-Base and Skywork-13BChat. The bottom is a robust basis mannequin with state-of-the-art Chinese language language modelling functionality, and the chat is a fined-tuned model optimized for conversations. Not like different organizations, they disclose detailed info on the coaching course of and knowledge composition. 

Additionally they launched intermediate checkpoints, which give a precious useful resource for understanding how the mannequin’s capabilities develop all through coaching. They consider this disclosure permits different researchers to leverage the checkpoints for his or her use instances. Additionally they developed a novel methodology that detects the extent of in-domain knowledge utilization throughout the coaching stage.

The staff skilled the Skywork-13B basis mannequin on SkyPile. As an alternative of coaching it on SkyPile as a complete, they adopted a two-stage coaching method. Within the first stage, they represent the first pretraining section, which entails coaching the mannequin from scratch on SkyPile-Essential. Within the second stage, it’s optimized with STEM-related area information and problem-solving expertise via continuous pretraining on SkyPile-STEM.

In the course of the mannequin’s coaching, the staff examined the language modeling loss throughout quite a few reserved validation units, every reflecting a definite knowledge distribution by creating separate validation units for code, educational publications, social media posts, and net texts in Chinese language and English. They are saying following this method results in ease in development, simplicity in computation, excessive sensitivity to coaching progress, and model-agnosticism.

Skywork-13B mannequin reveals the most effective efficiency general. It obtained the bottom common perplexity rating of 9.42. It additionally reveals the most effective efficiency throughout particular person domains, attaining the bottom perplexity scores within the tech, film, authorities, and finance domains. It excels not solely in surpassing the efficiency of fashions of an identical measurement but additionally in outperforming considerably bigger fashions corresponding to InternLM-20B and Aquila2-34B.
