Libraries

How to use KKanno/qwen3-4b-structeval-sft-merged with Transformers:

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

pipe = pipeline("text-generation", model="KKanno/qwen3-4b-structeval-sft-merged")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("KKanno/qwen3-4b-structeval-sft-merged")
model = AutoModelForCausalLM.from_pretrained("KKanno/qwen3-4b-structeval-sft-merged")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

qwen3-4b-structeval-sft-merged

This model is a merged version of:

Base: Qwen/Qwen3-4B-Instruct-2507
Adapter: KKanno/qwen3-4b-structeval-sft-lora-2epoch

It was fine-tuned for structured output generation (JSON/YAML/XML/CSV).

Notes

This repository contains merged full weights (16-bit).
No LoRA adapter loading is required at inference time.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "KKanno/qwen3-4b-structeval-sft-merged"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.float16,
    device_map="auto"
)

prompt = "Generate JSON output."
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0]))
