That's a **hallucination**: the AI states something false as if it were fact, and it's one of the biggest reasons people hesitate to trust these tools.\n\n[Samsung](https://patentlyze.com/samsung/)'s filing describes a way to teach an image-reading AI to catch itself. Instead of hiring people to grade answers, or paying another company's AI to do it, the system has an AI write several different descriptions of the same photo. A second tool then scores how well each description matches the picture. The best-scoring description becomes the \"right\" example, and the worst one becomes the \"wrong\" example.\n\nThose pairs are then used to retrain the AI so it leans toward accurate answers and away from believable but false ones. The photos are ones the AI was already trained on, so nothing new has to be collected.\n\n## How the AI picks its best and worst captions\n\nThe filing covers a method for building a **training dataset** (a collection of examples an AI studies to improve) that is used to fine-tune a **vision-language model** (an AI that handles both pictures and text, such as one that captions photos or answers questions about them).\n\nFor each image, the method runs these steps:\n\n- A pretrained vision-language model writes several captions for the image.\n- Each caption gets a score for how well it matches the image. The filing's example uses CLIP, a model trained to measure image-text similarity, which compares **embeddings** (lists of numbers that capture meaning) using cosine similarity.\n- The captions are ranked, and the top and bottom ones become the positive and negative labels.\n- The image and its label pair are saved to the dataset.\n\nThe filing also describes using at least two different prompts to get varied captions, and a route where a language model turns a caption into a question with one correct answer and one believable wrong answer.\n\nFilters keep the pairs useful. Captions below a score threshold (28.0 in one example) are dropped as too obviously wrong, overly long captions are removed, and pairs of different lengths are discarded so the AI doesn't learn that short means bad. The pair with the biggest score gap is kept, and training then pushes the model toward the positive caption.\n\n## Why cheaper AI grading matters for photo chatbots\n\nIf you ask a chatbot about a screenshot, a webpage or your own notes, you want an answer that matches what is on the screen. The filing mentions exactly those uses: a visual chatbot that answers questions about an image or a page, and a tool that searches through notes and slides that mix pictures and text. Fewer invented details would make those tools easier to trust.\n\nThe cost angle may matter just as much. The filing faults older approaches for needing extra data, several models and a paid GPT-4 service to rank answers. Samsung's version reuses photos the model has already seen, and it reports fine-tuning on about 0.7 million samples. Those results come from Samsung's own testing, so treat the comparisons to larger models as claims for now.\n\nThat makes this Samsung's 13th filing we've tracked in our [AI safety checks race](https://patentlyze.com/watchlist/the-ai-guardrails-race/) since June, adding to earlier applications like [one checking car alerts](https://patentlyze.com/patent/samsung-ai-checks-car-robot-warning-alerts/) and [one fact-checking voice answers](https://patentlyze.com/patent/samsung-voice-assistant-checks-answers/).\n\nMade-up details are a real problem for AI that looks at pictures. If a tool misreads a receipt, a medicine label or a webpage and invents a detail, you may act on something false, and the answer usually sounds just as sure as a correct one.\n\nThe approach fits the size of that problem. Grading AI answers has been expensive, because it takes people or a paid outside AI, and Samsung's method has the model's own captions do most of the work on photos it has already seen. Cheap grading can be repeated across many models and updates, which matters for a flaw this widespread.\n\nHallucinations will probably persist after this kind of training, and the reported gains come from Samsung's own tests. Still, a low-cost way to chip away at a costly flaw is a sensible match for the job.\n\nGet our take in your Top Stories\n\nLiked this breakdown?
