Introduction
AMPO, a novel framework that intelligently leverages guidance from multiple, diverse teacher models, intervening only when the on-policy model fails. Our two core contributions, Adaptive Multi-Guidance Replacement and Comprehension-based Guidance Selection, ensure that this external knowledge is used both efficiently and effectively.
Key Highlights:
- Adaptive Multi-Guidance Replacement: Minimizes intervention by providing external guidance only upon complete on-policy failure, preserving self-discovery while enhancing reasoning efficiency.
- Comprehension-based Guidance Selection: Improves learning effectiveness by guiding the model to assimilate the most comprehensible external solutions, demonstrably boosting performance.
- Superior Performance: Achieves better performance and efficiency compared to using RL or SFT alone.
Multi-Guidance Pool
Teacher Models: AceReason-Nemotron-1.1-7B, DeepSeek-R1-Distill-Qwen-7B, OpenR1-Qwen-7B, Qwen3-8B(thinking)
Inference Example
Here’s an example of using AMPO for inference:
from transformers import AutoTokenizer
from vllm import LLM, SamplingParams
model_path = "SII-Enigma/Qwen2.5-7B-Ins-SFT-32k"
question = "which number is larger? 9.11 or 9.9?"
tokenizer = AutoTokenizer.from_pretrained(model_path)
messages = [{"role": "user", "content": question}]
chat = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
llm = LLM(model=model_path)
params = SamplingParams(temperature=0.6, max_tokens=8192)
outputs = llm.generate([chat], params)
print(outputs[0].outputs[0].text)

AMPO builds upon LUFFY, veRL, RLPR and utilizes vLLM for inference. We utilize Math-Verify for math reasoning evaluation. We thank the open-source community for codes, datasets and backbones.
