PRIME: An Open-Source Solution for Online Reinforcement Learning with Process Rewards to Advance Reasoning Abilities of Language Models Beyond Imitation or Distillation

Challenges with Large Language Models (LLMs)

Large Language Models (LLMs) struggle to improve reasoning due to a need for more high-quality training data. To address this, exploration-based methods like reinforcement learning (RL) provide a better path forward.

Key Solutions and Innovations

A new method called PRIME (Process Reinforcement through IMplicit Rewards) enhances LLM reasoning through online RL using process rewards. This method creates rewards without needing explicit labels, leading to a more efficient training process.

Performance Improvements

By employing PRIME, researchers developed the Eurus-2-7B-PRIME model, achieving significant performance boosts with a fraction of the data compared to previous models. The system combines different math and coding datasets, carefully selecting prompts to optimize learning.

PRIME’s Systematic Approach

PRIME starts with a foundational model and progresses through generating rollouts, scoring them, and updating models based on a mixture of outcome and process rewards. With this method, Eurus-2-7B-PRIME outperformed other models using only 10% of the data, achieving notable improvements in training speed and accuracy.

Validation and Quality Assurance

To ensure high-quality results, PRIME uses advanced models for validating problem-solving and solution accuracy. Each question undergoes extensive validation to confirm its reliability and correctness.
