DeepSeek‐Coder V1 - amosproj/amos2025ss04-ai-driven-testing GitHub Wiki

DeepSeek-Coder-V1 is an open-source large language model developed by DeepSeek-AI, specifically optimized for code generation and understanding. It is released under a permissive MIT license, allowing both research and commercial usage.


🔍 Overview

DeepSeek-Coder-V1 was trained from scratch on a massive corpus of around 2 trillion tokens, composed of 87% code and 13% natural language [1]. This training enables the model to handle a broad range of programming tasks, from code generation and completion to infilling and explanation.


🔧 Key Features

  • Wide Language Support:
    Supports 87 programming languages, including Python, Java, C++, JavaScript, Go, Rust, HTML, SQL, Bash, and many more.

  • Context Window:
    Processes up to 16K tokens, making it well-suited for large codebases and long coding tasks.

  • Multiple Model Sizes:
    Available in different sizes to accommodate different hardware setups:

    • 1.3B parameters
    • 5.7B parameters
    • 6.7B parameters
    • 33B parameters
  • Fine-Tuning Support:
    The official GitHub repository also provides fine-tuning versions of DeepSeek-Coder-V1, enabling users to adapt the model to their own datasets and specific tasks [2].

  • State-of-the-Art Performance:
    Achieves strong results in open-source benchmarks for code intelligence, outperforming many older models like Codex and GPT-3.5 in various tasks.


🧠 Architecture

DeepSeek-Coder-V1 is built on a standard transformer architecture, emphasizing simplicity, efficiency, and broad compatibility.
