Xmodel-1.5: An 1B-scale Multilingual LLM
Authors: name: Wang Qun, name: Liu Yang, name: Lin Qingquan, name: Jiang Ling

We introduce Xmodel-1.5, a novel 1-billion-parameter multilingual large model
pretrained on approximately 2 trillion tokens. The model demonstrates strong
performance across several languages, with particularly notable results in
Thai, Arabic, and French, alongside its effectiveness in Chinese and English.
In addition, we contribute to the research community by releasing a Thai
evaluation dataset, which includes hundreds of questions annotated by students
from Chulalongkorn University's School of Integrated Innovation. While the
results are promising, we acknowledge that there is still room for improvement.
We hope this work advances ongoing efforts in multilingual AI research and
promotes better cross-linguistic understanding in various natural language
processing tasks. Our models and code are publicly available on GitHub at
