+# Model Card for bartpho-word-cpo-summarize-vietgpt-256
+
+This model is a fine-tuned version of [sonspeed/bartpho-vietgpt](https://huggingface.co/sonspeed/bartpho-vietgpt).
+It has been trained using [TRL](https://github.com/huggingface/trl).
+
+## Quick start
+
+```python
+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="sonspeed/bartpho-word-cpo-summarize-vietgpt-256", device="cuda")
+output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
+print(output["generated_text"])
+```
+
+## Training procedure

+
+
+This model was trained with CPO, a method introduced in [Contrastive Preference Optimization: Pushing the Boundaries of LLM Performance in Machine Translation](https://huggingface.co/papers/2401.08417).
