arXiv:2603.12433v3 Announce Type: replace-cross Abstract: Model stitching, connecting early layers of one model (source) to later layers of another (target) via a light stitch layer, has served as a probe of representational compatibility. Prior work finds that models trained on the same dataset remain stitchable (negligible accuracy drop) despite different initializations or objectives. We revisit stitching for Vision Foundation Models (VFMs) that vary in objectives, data, and modality mix (e.g., CLIP, DINOv2, SigLIP 2) and ask: Are heterogeneous VFMs stitchable? We introduce a systematic pro
The proliferation of diverse Vision Foundation Models (VFMs) from various sources makes understanding their interoperability and compositional potential increasingly critical.
This research provides insights into the fundamental compatibility of different large AI models, which impacts strategies for building more complex and robust AI systems.
The ability to 'stitch' different foundation models implies new paradigms for AI development, potentially democratizing access to specialized AI capabilities by combining existing components.
