Auditing Models for Capability Gap Discovery and Rectification
This paper introduces AuditDM, an automated framework for discovering and rectifying failure modes in Multimodal Large Language Models (MLLMs). By training an MLLM auditor with reinforcement learning, AuditDM generates challenging questions and counterfactual images that maximize disagreement among target models, exposing capability gaps. The framework converts these discoveries into annotation-free training data, significantly improving model performance across benchmarks and enabling smaller models to outperform larger counterparts.
Executive Impact & Key Takeaways
AuditDM offers a scalable, data-efficient path to improve multimodal models without additional supervision, positioning it as an effective tool for uncovering and remedying capability gaps in MLLMs.
- AuditDM systematically discovers MLLM capability gaps via cross-model divergence.
- It uses reinforcement learning to generate failure-inducing question-image pairs.
- Discovered failure modes are converted into annotation-free training data for rectification.
- AuditDM leads to significant performance gains, allowing a 3B model to surpass a 28B model.
- The framework provides interpretable insights into model weaknesses and decision boundaries.

Case Study: 3B Model Surpasses 28B
AuditDM-trained 3B PaliGemma2 outperforms its 28B counterpart on several benchmarks.
Challenge: Conventional evaluations often obscure how models truly differ, especially when retraining or fine-tuning.
Solution: AuditDM generates weakness-targeted data to fine-tune smaller models, addressing specific capability gaps.
Result: PaliGemma2-3B with AuditDM achieved 85.3 on AI2D, surpassing the 28B model's 84.6. On MMBench, Gemma3-4B with AuditDM reached 75.0, surpassing Gemma3-12B's 73.8.
Discusses the current limitations and future work of the AuditDM approach.

Implementation Roadmap
A phased approach to integrate AuditDM and realize continuous MLLM improvement.
Phase 1: Setup & Auditor Training
Integrate AuditDM framework with your target MLLM and reference ensemble. Train the AuditDM auditor using reinforcement learning to identify initial failure modes. (~2-4 weeks)
Phase 2: Data Generation & Rectification Cycle 1
Leverage the trained auditor to generate large-scale, weakness-targeted training data. Fine-tune your target MLLM on this augmented dataset to address identified capability gaps. (~4-8 weeks)
Phase 3: Iterative Auditing & Improvement
Retrain the auditor on the improved MLLM to discover new or remaining weaknesses. Repeat the data generation and fine-tuning cycle for continuous model improvement and robustness. (~Ongoing)
Phase 4: Deployment & Monitoring
Deploy the enhanced MLLM and integrate AuditDM for real-time monitoring of performance and detection of emerging failure modes in production. (~Ongoing)
