Large language models (LLMs) are rapidly evolving, but adding visual capabilities often leads to them forgetting what they already knew about text. This "text-only forgetting" poses a significant challenge for building truly versatile AI. Imagine asking an AI assistant a series of questions, starting with text-based queries and then adding an image for more context. Ideally, the AI should seamlessly handle both, drawing on its textual knowledge even when processing images. However, many multimodal LLMs (MLLMs) struggle with this, performing worse on text tasks after being trained on image-text pairs. Researchers have discovered that this forgetting is related to how the MLLM’s “attention” shifts. When presented with an image, the model tends to overly focus on the visual information, neglecting the surrounding text. To address this, a novel approach called WINGS has been developed. WINGS acts like a balancing mechanism for the model’s attention. It incorporates two sets of "learners"—visual learners that focus on images and textual learners that focus on text. These learners work in tandem to compensate for the attention shift caused by visual input. Initial tests show promising results. WINGS outperforms existing MLLMs in both text-only and visual question-answering tasks, especially on complex, interleaved conversations where text and image inputs are mixed. The research suggests that the secret to building genuinely intelligent MLLMs lies in maintaining a balance between learning new modalities and retaining proficiency in existing ones. This work opens exciting new avenues for developing AI assistants capable of seamlessly blending text and images in more human-like conversations.

Question & Answers
How does the WINGS architecture prevent text-only forgetting in multimodal LLMs?
WINGS employs a dual-learner architecture that balances visual and textual attention. At its core, it uses two specialized sets of learners that work in parallel: visual learners for processing images and textual learners for handling text. When processing mixed inputs, WINGS actively maintains attention distribution between these learners, preventing the model from over-focusing on visual information. This is achieved through a compensation mechanism that ensures textual knowledge isn't overshadowed during image processing. For example, when answering a question about both historical text and an image of an artifact, WINGS can maintain context from both sources without losing previously learned textual knowledge about the historical period.
What are the benefits of multimodal AI systems in everyday applications?
Multimodal AI systems combine different types of input (like text and images) to provide more comprehensive and natural interactions. These systems can enhance user experiences by allowing people to communicate more naturally, just as humans do by combining speech, gestures, and visual information. Key benefits include more intuitive interfaces, better accessibility for diverse user needs, and more accurate understanding of context. For instance, in healthcare, a multimodal AI could analyze both written patient records and medical images to provide more accurate diagnoses, or in education, it could offer more engaging learning experiences by combining visual and textual explanations.
How are AI assistants evolving to handle multiple types of information?
AI assistants are rapidly evolving from simple text-based systems to sophisticated platforms that can process multiple forms of information simultaneously. This evolution enables them to understand context better and provide more accurate, comprehensive responses. The key advantages include more natural human-computer interaction, improved problem-solving capabilities, and enhanced user experience. In practical applications, modern AI assistants can help with tasks like visual search in e-commerce, creating content that combines text and images, or providing more detailed explanations using both visual and textual elements. This advancement makes AI assistance more valuable in fields like education, customer service, and creative work.
