Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("samarthraina/qwen2.5-7b-openhermes-v1")
tokenizer = AutoTokenizer.from_pretrained("samarthraina/qwen2.5-7b-openhermes-v1")

messages = [
    {"role": "user", "content": "Explain quantum computing in simple terms."}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt")

outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Hardware

—GPU: NVIDIA RTX 4090 (48GB)
—Training Time: ~21 hours

Limitations

—Trained on 250k samples (subset of full OpenHermes-2.5)
—Single epoch training
—Conservative hyperparameters (lr=2e-5, r=32)
—May not perform optimally on tasks outside the training distribution
