Introduction

LTE (Learning to reason from Trial and Error) is an RLVR (Reinforcement Learning with Verifiable Rewards) approach presented in the paper Do Not Step Into the Same River Twice: Learning to Reason from Trial and Error.

LTE mitigates the exploration stagnation of Language Models (LMs) by utilizing their previously self-made mistakes as hints, requiring no external expert guidance. It improves the performance upper bound of LMs and enhances both exploitation and exploration during training.

Key Highlights

• Self-generated Hints: LTE uses the errors generated by the LMs themselves during training as hints.
• No External Expert Guidance: LTE does not require any external expert guidance to mitigate the exploration stagnation of LMs.

Inference

Here is an example of using LTE models for inference:

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

model_path="JamyDohrn/LTE-Qwen3-8B-Base"

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=32768)
outputs = llm.generate([chat], params)
print(outputs[0].outputs[0].text)
