Researchers have developed a new benchmark called PatternEval to assess multimodal large language models (MLLMs) that use hybrid-thinking approaches. This benchmark identifies common failure modes such as chain-of-thought leakage, response repetition, logical contradiction, and performative reasoning. The study found that these response-pattern failures are prevalent, particularly in non-thinking inference modes, leading to misalignment between different inference strategies. To address this, the team introduced PatternRM, a reward model, and PatternRL, a reinforcement learning technique that incorporates pattern-specific penalties, demonstrating its effectiveness in mitigating misalignment on Qwen3-VL models.
