Model Card for Qwen2.5-7B-Instruct-Jokester-English

This model is a fine-tuned version of Qwen/Qwen2.5-7B-Instruct. It has been trained using TRL. The reward signal during GRPO training was provided by joke-rater-roberta-en.

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="KonradBRG/Qwen2.5-7B-Instruct-Jokester-English", 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 GRPO, a method introduced in DeepSeekMath: Pushing the Limits of Mathematical Reasoning in Open Language Models.

Framework versions

• TRL: 0.23.1
• Transformers: 4.57.3
• Pytorch: 2.9.1
• Datasets: 4.4.1

    abstract = "This paper addresses the challenge of computational humor generation proposed in SemEval-2026 Task 1: Humor Generation. Our approach leverages Group Relative Policy Optimization, with an LLM serving as the policy and a custom joke rating model providing a reward signal. We demonstrate that this framework is an effective and computationally efficient approach, reliably producing genuinely funny content that adheres to task constraints."
