Worked on the cloudwego/eino-ext repository to deliver configurable endpoint support for the DeepSeek chat model, focusing on enhancing integration flexibility and supporting multi-environment deployments. The primary feature involved implementing a configurable BaseURL within the ChatModelConfig, allowing users to specify custom API endpoints such as https://api.deepseek.com/beta. This approach decoupled endpoint configuration from the core logic, streamlining both testing and deployment processes. The work emphasized robust configuration management patterns and clear example code, enabling easier adoption for teams integrating with DeepSeek. Utilized Go for development, applying skills in API integration and configuration management to address evolving deployment requirements.
