Domain-agnostic multilingual humor pretraining checkpoint at 14B scale. Trained on the SemEval MWAHAHA headline corpus across all languages. Serves as a general-purpose multilingual humor generator and as the starting point for the HumorGen JOKER cross-lingual fine-tuning.

Training

Property	Value
Stage	Supervised Fine-Tuning (SFT)
Backbone	Qwen3-14B (QLoRA 4-bit)
LoRA r / alpha	16 / 16
Data	SemEval MWAHAHA — all languages

Usage

This is a PEFT LoRA adapter. Load the base model and apply the adapter:

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3-14B")
model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-14B", torch_dtype=torch.bfloat16, device_map="auto")
model = PeftModel.from_pretrained(model, "Jayi2424/HumorGen_SFT_14B")

headline = "Scientists discover caffeine is just hope in liquid form"
prompt = (
    "<|im_start|>system\n"
    "You are a comedy writer. Write one sharp, witty joke for the headline.\n<|im_end|>\n"
    f"<|im_start|>user\n{headline}<|im_end|>\n"
    "<|im_start|>assistant\n"
)
inputs  = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=120, temperature=0.9, top_p=0.95)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
