But a new approach favors trust over fusion, improving accuracy in factual QA.\n\n[Multimodal](/glossary/multimodal) retrieval-augmented generation ([RAG](/glossary/rag)) has been the cool kid on the block generating content using both text and images. But here's the kicker: while these systems are evaluated with pristine data, the real world isn't so kind. We're talking about misleading images, false text, and tricky edits. All these can throw a wrench in the works.\n\n## The QIMG-7 [Benchmark](/glossary/benchmark)\n\nEnter QIMG-7, a new benchmark designed to put these systems through their paces. It covers four datasets and seven types of image attacks, giving us a whopping 1,760 scenarios per method to chew on. And the results? Naive multimodal fusion really struggles.\n\nTake the [gpt](/glossary/gpt)-4o-mini stack, for instance. Its performance with clean text is solid at 0.908. But throw in some polluted text, and it nosedives to 0.490. Clearly, when the data gets messy, relying on Parametric fallback instead of retrieval is often a safer bet.\n\n## Trust Before Fusion\n\nThis is where source-aware trust resolution (SATR) comes into play. It doesn't need any special [training](/glossary/training), just a good old-fashioned dose of common sense. SATR evaluates the reliability of sources and chooses answers based on that trust. The Field-Selector variant even scores an impressive 0.816, outpacing Full-MM by 11.7 points.\n\nHere's the crux: while it might be tempting to just mix everything together, this shows that selective trust wins the day. In fact, the gains here are largely due to focusing on text reliability. And let's be honest, in a world where anyone can doctor an image, isn't it about time we got more skeptical?\n\n## Why It Matters\n\nSo why should you care? This isn't just technical mumbo jumbo. It's about the AI systems we rely on getting things right. If you're asking factual questions, you want solid answers. And when multimodal retrieval returns mixed results, knowing when to trust the source can make all the difference.\n\nSo, what's next? Will AI builders take this as a cue to prioritize trust over flashy fusion? As we've seen, the meta shifted.
