Libraries

How to use tomhu/RL4TG-Qwen2.5-3B-OPD-7B-Teacher with Transformers:

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

pipe = pipeline("text-generation", model="tomhu/RL4TG-Qwen2.5-3B-OPD-7B-Teacher")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("tomhu/RL4TG-Qwen2.5-3B-OPD-7B-Teacher")
model = AutoModelForCausalLM.from_pretrained("tomhu/RL4TG-Qwen2.5-3B-OPD-7B-Teacher", device_map="auto")
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]:]))

Qwen2.5-3B + OPD (7B Teacher)

This is an RL4TG checkpoint for Java unit-test generation.

Field	Value
Base model	`Qwen/Qwen2.5-3B-Instruct`
Method	Online Policy Distillation (OPD)
Teacher	`Qwen/Qwen2.5-Coder-7B-Instruct`
Released checkpoint	final step 152
Training data	Defects4J project-disjoint training split
Prompt format	Qwen2.5 chat template
Global training seed	42

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "tomhu/RL4TG-Qwen2.5-3B-OPD-7B-Teacher"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

The model is intended for research on Java unit-test generation. Generated tests must still be compiled and executed in the target project's own build environment.
