Yann LeCun: New Vision Language JEPA with Better Performance Than LLMs (arxiv.org)

Yann LeCun's team has introduced VL-JEPA (Vision-Language Joint Embedding Predictive Architecture), a groundbreaking model that challenges the traditional autoregressive methods used in most vision-language models (VLMs). Instead of generating tokens, VL-JEPA predicts continuous embeddings, learning to navigate semantics while minimizing surface-level variability. This innovative approach not only slashes the number of trainable parameters by 50% but also enhances performance across various tasks. Notably, the model employs a lightweight text decoder only when necessary, enabling a 2.85x reduction in decoding operations without sacrificing accuracy. The significance of VL-JEPA lies in its versatility and efficiency, demonstrated by its superior performance over existing frameworks like CLIP and SigLIP2 across eight video classification and retrieval datasets. Additionally, it maintains competitive results on visual question answering tasks compared to established VLMs like InstructBLIP, despite having just 1.6 billion parameters. This model's capability for open-vocabulary classification and text-to-video retrieval further marks a pivotal step in the evolution of AI/ML, signaling a potential shift towards more efficient and effective multimodal systems.
