GemCod270M - Jade (gemma-270m-it-code v4.1.0)

GemCod is a lightweight code generation model finetuned using SFT on the base gemma-270m-it model(https://huggingface.co/google/gemma-3-270m-it). It offers accurate and quick(ish) code snippet and long-form code generation in all major programming languages. It's small size (270M parameters) allows it to run comfortably on laptop grade GPUs.

The Jade model serves as an upgrade from the previous Aquamarine model(https://huggingface.co/DireDreadlord/GemCod-codegen-270M), as it provides facilities for superior long-form code generation and explainability of generated snippets whilst keeping the inference time and space requirements roughly the same.

This model also offers rudimentary Q/A and subject matter expert capabilities on code related subjects.

Estimated parameters: ~270M

Architecture: Gemma3

Intended use: Code snippet and long-form code generation from natural language

Training data

Source: magicoder-glaive-code-instruct dataset (https://huggingface.co/datasets/DireDreadlord/magicoder-glaive-code-instruct)
Rows: ~350,000 rows templated with a custom .jinja chat format
Training: trained for 3,000 steps on an RTX 3050 (4GB VRAM)

Usage

Install requirements:

pip install -r requirements.txt
pip install transformers datasets accelerate safetensors
