The article delves into the intricacies of vision-language models (VLMs), detailing the importance of combining vision and language backbones effectively. It poses questions about the equivalence of pre-trained backbones, compares different architectural frameworks (fully autoregressive vs. cross-attention), and discusses strategies for optimizing compute and performance. Additionally, it introduces Idefics2, an advanced vision-language foundation model, highlighting its multi-stage pre-training, instruction fine-tuning, and optimizations for chat scenarios. The article emphasizes the need for shared terminology in understanding and discussing the varied design choices involved in VLMs.
Training vision-language models typically integrates a pre-trained vision backbone with a language backbone, often leveraging large multimodal datasets for effective model performance.
Exploring design choices in vision-language models reveals that different architectural frameworks significantly influence the efficiency and performance trade-offs of the models.
