Usage

Using the Model

This model uses a custom configuration format and requires the OpenLLM framework to load properly.

# Load using the OpenLLM framework
from core.src.model import GPTModel
import json
import torch

# Load configuration
with open("config.json", "r") as f:
    config = json.load(f)

# Create model instance
model = GPTModel(config["model_config"])

# Load trained weights
model.load_state_dict(torch.load("pytorch_model.bin", map_location="cpu"))

# Load tokenizer
import sentencepiece as spm
tokenizer = spm.SentencePieceProcessor()
tokenizer.load("tokenizer.model")

# Generate text
prompt = "The future of artificial intelligence"
tokens = tokenizer.encode(prompt)
inputs = torch.tensor([tokens], dtype=torch.long)

with torch.no_grad():
    outputs = model.generate(
        inputs,
        max_length=100,
        temperature=0.7
    )

generated_text = tokenizer.decode(outputs[0].tolist())
print(generated_text)

Using the Custom Loader

from load_hf_model import load_model_and_tokenizer

# Load model using custom loader
model, tokenizer = load_model_and_tokenizer("lemms/openllm-small-extended-10k")

# Generate text
prompt = "The history of machine learning"
tokens = tokenizer.encode(prompt)
inputs = torch.tensor([tokens], dtype=torch.long)

with torch.no_grad():
    outputs = model.generate(
        inputs,
        max_length=100,
        temperature=0.7
    )

print(tokenizer.decode(outputs[0].tolist()))

Model Architecture

This model follows the standard GPT architecture:

Token Embeddings: Maps token IDs to dense vectors
Positional Embeddings: Adds position information
Transformer Blocks: 6 layers with multi-head attention and feed-forward networks
Layer Normalization: Pre-norm placement for training stability
Output Head: Linear projection to vocabulary for next-token prediction

Training Details

The model was trained using:

Framework: PyTorch
Hardware: CPU training with gradient accumulation
Regularization: Dropout (0.1), weight decay
Optimization: AdamW with cosine learning rate scheduling
Gradient Clipping: 1.0

Limitations

This is a small model (35.8M parameters) with limited capacity
Training was done on CPU, which limited the training steps
Model quality is basic and suitable for educational/research purposes
Not suitable for production use without further training
