SPT: A Lightweight Language Model

NanoLlama is a compact language model trained on Sherlock Holmes stories.

Model Details

• Model Type: NanoLlama (Causal Language Model)
• Number of Layers: 12
• Hidden Size: 512
• Number of Attention Heads: 16
• Number of KV Heads: 16
• Intermediate Size: 2048
• Maximum Sequence Length: 2048
• Vocabulary Size: 97 (including special tokens)

Usage

You can use this model with the Hugging Face Transformers library:

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("imdatta0/spt")
model = AutoModelForCausalLM.from_pretrained("imdatta0/spt")

# Generate text
input_text = "Sherlock and I were "
input_ids = tokenizer(input_text, return_tensors="pt").input_ids
output = model.generate(input_ids, max_length=50, num_return_sequences=1)

generated_text = tokenizer.decode(output[0], skip_special_tokens=True)
print(generated_text)

Training

This model was trained on Sherlock Holmes' stories on a single A100 with a batch size of 2 and gradient accumulation steps of 32 effective batch size of 64. It was trained on 1024 length character sequences for 10000 steps.

Limitations

• The model has a limited vocabulary of 97 tokens, which may affect its performance on certain tasks or domains.
• The maximum sequence length is 2048 tokens, which may not be sufficient for very long text generation tasks.
