Instructions to use MinKeonKim/PRO-STEP-Policy-7B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use MinKeonKim/PRO-STEP-Policy-7B with Transformers:

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

pipe = pipeline("text-generation", model="MinKeonKim/PRO-STEP-Policy-7B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("MinKeonKim/PRO-STEP-Policy-7B")
model = AutoModelForCausalLM.from_pretrained("MinKeonKim/PRO-STEP-Policy-7B")
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]:]))

PRO-STEP: Step-level Process Reward Optimization for RAG (Policy Model)

This is the main policy model for PRO-STEP, a self-improving framework for agentic Retrieval-Augmented Generation. The policy is trained on its own MCTS trajectories scored by an open-source 8B PRM, using step-level DPO.

Backbone: Qwen2.5-7B-Instruct
PRM: DORAEMONG/PRO-STEP-PRM-8B
Preference data: DORAEMONG/PRO-STEP-Preference-Data
Training: DPO (β=0.1) with document-token masking, LoRA r=64/α=128, 1 epoch, 5,000 questions / 15,877 step-level preference pairs
MCTS: K=3 branching, depth 7, 64 rollouts/question, value V(s) = Q̄(s) + α · r̂(s) with α=0.3
