ImageBind: Holistic AI learning across six modalities

Meta has introduced ImageBind, an AI model capable of binding information from six modalities, including text, image/video, audio, depth, thermal, and inertial measurement units (IMU). The model learns a single embedding, or shared representation space, for all modalities, enabling machines to better analyze different forms of information together. ImageBind can outperform prior specialist models trained individually for one particular modality. The model is part of Meta’s efforts to create multimodal AI systems that learn from all possible types of data around them. ImageBind shows that image-paired data is sufficient to bind together these six modalities, enabling other models to understand new modalities without any resource-intensive training. The model’s strong scaling behavior allows it to substitute or enhance many AI models by enabling them to use other modalities. ImageBind also achieved new state-of-the-art performance on emergent zero-shot recognition tasks across modalities. The AI research community has yet to effectively quantify scaling behaviors that appear only in larger models and understand their applications. Meta hopes the research community will explore ImageBind and their accompanying published paper to find new ways to evaluate vision models and lead to novel applications.
