Transformers

How to use eyobed7b/tenacious-bench with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="eyobed7b/tenacious-bench")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

Model Card for simpo_judge_v1

This model is a fine-tuned version of unsloth/qwen2.5-0.5b-instruct-unsloth-bnb-4bit. It has been trained using TRL.

Quick start

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="None", 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.
