Usage
git clone https://github.com/KeisukeMiyamoto1324/lambda.git
cd lambda
python3 -m venv venv

Limitations
This model is not instruction-tuned or safety-aligned. It may generate incorrect, biased, unsafe, or low-quality text.
The model was trained on a limited Japanese corpus mixture and has not been evaluated on standard benchmarks.
