Overview

SpringSea 0.2 is a specialized language model developed by keisuke-miyako, fine-tuned from the google/gemma-4-E2B-it base model. With 5.1 billion parameters and a 32,768-token context length, its primary focus is on 4D code, the proprietary language for 4D application development.

Key Capabilities

  • 4D Code Generation: Excels at generating new code snippets in the 4D language.
  • Code Completion: Provides intelligent suggestions for completing 4D code.
  • Code Reasoning: Capable of understanding and reasoning about existing 4D code structures and logic.
  • Specialized for 4D Ecosystem: Designed to integrate and assist within the unique environment of 4D application development.

Training Details

The model has undergone LoRA (Low-Rank Adaptation) fine-tuning. Specific training runs, such as "0423-02" and "0423-01," involved text data of approximately 4.19 MB, with varying ranks, alphas, learning rates, and epochs, indicating iterative refinement to optimize its performance for 4D code tasks. The project's overarching goal is to create a comprehensive coding assistant for the entire 4D development ecosystem.
