## Training Data

This model was trained on a dataset of curated C/C++ code from multiple licenses (GPL-2.0, Apache-2.0, MIT, public domain, and some source-available licenses, etc.).
The original authors are not affiliated with or responsible for this model.

## Base Model

Base model: [Qwen/Qwen3-4B-Base](https://huggingface.co/Qwen/Qwen3-4B-Base)

## Fine-tuning Method

- Adapter: QLoRA
- Method: CPT
- Precision: trained with 4-bit base weights + BF16 compute, then merged to safetensors

## Training Details

- Training time: ~74 hours
- Hardware: 1x NVIDIA RTX 5060 Ti

## Notes

- This is an **L0 base model**, it is not instruction-tuned and may be more verbose with strict formatting request compared to an instruct model.
- Recommended usage is raw code continuation, or pairing with an external template strategy.

## Intended use

- Code generation for C/C++
- Fast code completion
- Examples and prototyping

## Constraints

- May produce incorrect code
- May reproduce identifiable upstream code fragments (including license headers) when prompted.
- Verify outputs, especially for memory safety and security-sensitive code.
