MM-RLHF: The Next Step Forward in Multimodal LLM Alignment
This groundbreaking research introduces MM-RLHF, a massive 120,000 human-annotated preference dataset, coupled with innovative alignment techniques like the Critique-Based Reward Model and Dynamic Reward Scaling. It aims to holistically enhance Multimodal Large Language Models (MLLMs) across crucial dimensions such as conversational ability and safety, moving beyond limited task-specific improvements to truly align MLLMs with human preferences.

The Foundation: MM-RLHF Dataset
The MM-RLHF dataset represents a significant leap forward in MLLM alignment. Comprising 120,000 fine-grained, human-annotated preference comparison pairs, it offers unparalleled size, diversity across image, video, and safety domains, and granular annotation details including scores, rankings, and textual explanations. This meticulous curation provides a robust and high-quality foundation for training more aligned and trustworthy MLLMs, addressing the limitations of prior datasets that often focus on specific domains or lack annotation depth.
Enhanced Feedback: Critique-Based Reward Model
Traditional scalar reward models often lack interpretability. MM-RLHF introduces a Critique-Based Reward Model (CRBM) that first generates detailed critiques of model outputs before assigning scores. This innovative approach provides enhanced interpretability and more informative feedback, guiding the alignment process more effectively. By leveraging enriched human annotations (augmented via GPT-4o) as learning targets, the CRBM learns to provide fine-grained scoring explanations, significantly improving the quality and transparency of reward signals.
Optimized Alignment: Dynamic Reward Scaling & MM-DPO
To further refine MLLM alignment, the paper proposes Dynamic Reward Scaling (DRS) within the Direct Preference Optimization (DPO) framework. Unlike traditional DPO, which uses fixed training weights, DRS adjusts the loss weight of each sample based on its reward margin, prioritizing high-confidence comparison pairs. This ensures that the most informative samples have a stronger influence on model updates, leading to a more efficient training process and improved model performance. This dynamic adjustment mechanism addresses the challenges of diverse data quality in large multimodal datasets.
Robust Validation & Transformative Results
The MM-RLHF approach is rigorously evaluated across 10 distinct dimensions and 27 benchmarks, demonstrating significant and consistent performance improvements. Specifically, fine-tuning LLaVA-ov-7B with MM-RLHF and the proposed alignment algorithm leads to a 19.5% increase in conversational abilities and a 60% improvement in safety. The MM-RLHF-Reward-7B model also achieves state-of-the-art performance in reward modeling benchmarks, often outperforming much larger or closed-source models, underscoring the effectiveness of the entire alignment pipeline.
