Steel-LLM:From Scratch to Open Source -- A Personal Journey in Building
  a Chinese-Centric LLM
Authors: name: Qingshui Gu, name: Shu Li, name: Tianyu Zheng, name: Zhaoxiang Zhang

Steel-LLM is a Chinese-centric language model developed from scratch with the
goal of creating a high-quality, open-source model despite limited
computational resources. Launched in March 2024, the project aimed to train a
1-billion-parameter model on a large-scale dataset, prioritizing transparency
and the sharing of practical insights to assist others in the community. The
training process primarily focused on Chinese data, with a small proportion of
English data included, addressing gaps in existing open-source LLMs by
providing a more detailed and practical account of the model-building journey.
Steel-LLM has demonstrated competitive performance on benchmarks such as CEVAL
and CMMLU, outperforming early models from larger institutions. This paper
provides a comprehensive summary of the project's key contributions, including
data collection, model design, training methodologies, and the challenges
encountered along the way, offering a valuable resource for researchers and
practitioners looking to develop their own LLMs. The model checkpoints and
training script are available at https://github.com/zhanshijinwat/Steel-LLM.
