DMaS-LLaMa-Lite-step-500

This repository provides access to DMaS-LLaMa-Lite-step-500, a 1.7-billion-parameter language model based on the LLaMa architecture. The model has been trained from scratch as part of the DMaS-LLaMa-Lite project using approximately 20 billion tokens of high-quality educational content.

Model Overview

Architecture: LLaMa-based
Parameters: 1.7B (36 layers, 32 attention heads, RMSNorm)
Tokenizer: GPT-2 tokenizer
Training Data: FineWeb-Edu subset (educational text)
Training Steps: 500
Optimizer: AdamW with linear warmup and decay
Hardware: Trained on 1-2 RTX A6000 GPUs with PyTorch DDP
Dataset Source: FineWeb-Edu Dataset

The training process emphasizes qualitative improvements in coherence, fluency, and factual grounding, demonstrating competitive results even with fewer tokens compared to larger-scale models.

This checkpoint represents the model's state at 500 training steps. Validation loss and downstream performance benchmarks demonstrate notable early improvements in text fluency and alignment with prompts.

Training Code

The training script, including configurations and instructions, is open-sourced and available here:

Usage

You can load the model with Hugging Face Transformers library:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "McGill-DMaS/DMaS-LLaMa-Lite-step-500"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

inputs = tokenizer("The Pyramids of Giza in Egypt are some of the oldest man-made structures in the world.", return_tensors="pt")
outputs = model.generate(**inputs, max_length=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
