How to use Ceachi/HW2-dpo with Transformers:
# Use a pipeline as a high-level helper
from transformers import pipeline
pipe = pipeline("text-generation", model="Ceachi/HW2-dpo") # Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("Ceachi/HW2-dpo")
model = AutoModelForCausalLM.from_pretrained("Ceachi/HW2-dpo")How to use Ceachi/HW2-dpo with vLLM:
# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "Ceachi/HW2-dpo"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/completions" \
-H "Content-Type: application/json" \
--data '{
"model": "Ceachi/HW2-dpo",
"prompt": "Once upon a time,",
"max_tokens": 512,
"temperature": 0.5
}'docker model run hf.co/Ceachi/HW2-dpo
How to use Ceachi/HW2-dpo with SGLang:
# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
--model-path "Ceachi/HW2-dpo" \
--host 0.0.0.0 \
--port 30000
# Call the server using curl (OpenAI-compatible API):

docker model run hf.co/Ceachi/HW2-dpo
This model is a fine-tuned version of openai-community/gpt2. It has been trained using TRL.
from transformers import pipeline
question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="Ceachi/HW2-dpo", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])
This model was trained with ORPO, a method introduced in ORPO: Monolithic Preference Optimization without Reference Model.
