What are the challenges of scaling multimodal AI models?

Scaling multimodal AI models presents several challenges, including increased computational resource demands, data heterogeneity, and complexity in model architecture. Different modalities require different processing techniques and data alignment, complicating model training and integration. Moreover, training large-scale multimodal models necessitates vast amounts of diverse data to ensure effective learning, which can be difficult to curate and preprocess. Lastly, ensuring that the models generalize well across different tasks and domains poses additional challenges.
