Usage

Using Transformers

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

# Load model and tokenizer
model_name = "lemms/openllm-small-extended-6k"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Generate text
prompt = "The history of artificial intelligence"
inputs = tokenizer(prompt, return_tensors="pt")

with torch.no_grad():
    outputs = model.generate(
        inputs.input_ids,
        max_new_tokens=50,
        temperature=0.7,
        top_k=40,
        do_sample=True
    )

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

Using the Custom Loader

# Use the provided load_hf_model.py script
from load_hf_model import load_model_and_tokenizer

model, tokenizer = load_model_and_tokenizer()
# ... rest of usage
