CodeShell Technical Report
CoRR(2024)
摘要
Code large language models mark a pivotal breakthrough in artificial
intelligence. They are specifically crafted to understand and generate
programming languages, significantly boosting the efficiency of coding
development workflows. In this technical report, we present CodeShell-Base, a
seven billion-parameter foundation model with 8K context length, showcasing
exceptional proficiency in code comprehension. By incorporating Grouped-Query
Attention and Rotary Positional Embedding into GPT-2, CodeShell-Base integrates
the structural merits of StarCoder and CodeLlama and forms its unique
architectural design. We then carefully built a comprehensive data
pre-processing process, including similar data deduplication, perplexity-based
data filtering, and model-based data filtering. Through this process, We have
curated 100 billion high-quality pre-training data from GitHub. Benefiting from
the high-quality data, CodeShell-Base outperforms CodeLlama in Humaneval after
training on just 500 billion tokens (5 epochs). We have conducted extensive
experiments across multiple language datasets, including Python, Java, and C++,
and the results indicate that our model possesses robust foundational
capabilities in code comprehension and generation.
