Pricing Detail

Free: Fully open-source — MIT code license, commercial-use-permitted model license
Paid: N/A — self-hosted, no API fees

⚠ Known Limitations

  • ⚠ Larger models (33B) require significant GPU resources
  • ⚠ 16K context window may be insufficient for very large codebases
  • ⚠ No hosted API — requires self-deployment infrastructure
  • ⚠ Training data cutoff limits knowledge of newest frameworks/libraries

Pros

  • + 支持80多种编程语言，覆盖范围极广，从主流语言到领域特定语言应有尽有
  • + 提供1B到33B多种参数规格，用户可根据计算资源和性能需求灵活选择
  • + 采用16K窗口大小和项目级训练，能够理解较长的代码上下文和项目结构

Cons

  • - 大参数版本对计算资源要求较高，可能需要专业的GPU硬件支持
  • - 作为生成式AI模型，可能产生不完全正确或不安全的代码，需要人工审查

Use Cases

  • • 项目级代码补全和智能提示，提高开发效率
  • • 代码填空和缺失部分补充，辅助代码重构和修复
  • • 多语言编程项目支持，为使用多种编程语言的复杂项目提供一致的代码辅助

Getting Started

1. 从Hugging Face下载适合您计算资源的模型版本（1B-33B）；2. 搭建推理环境并加载模型；3. 开始使用代码补全和填空功能进行编程辅助
