Exploring the Physics of Multimodal Pretraining: Knowledge Flow and Early Unification
_akhaliq · x · 2026-08-06
This paper investigates the underlying mechanisms of multimodal pretraining. Despite the shift towards natively unified multimodal pretraining in foundation models, the design space and fundamental mechanisms of how modalities interact during unified training remain underexplored.
The paper provides empirical clarifications on the "physics" of multimodal pretraining, focusing on key dimensions:
- Knowledge Flow: The pathways and patterns of knowledge transfer between different modalities.
- Modality Synergy: How multiple modalities mutually enhance overall performance.
- Early Unification: The advantages and strategies of fusing modalities at the early stages of pretraining.
