This article discusses the construction and training of Idefics2, an advanced vision-language model with 8 billion parameters. It highlights the three-phase pre-training approach utilizing OBELICS, a dataset featuring interleaved image-text documents that significantly contributes to performance gains, particularly in visual question answering (VQA). The authors emphasize the model's fine-tuning for chat scenarios and comparisons with existing vision-language models, showcasing its state-of-the-art capabilities and efficiency metrics. Overall, Idefics2 aims to set a benchmark in the field of vision-language integration.
The development of Idefics2 involves a comprehensive multi-stage pre-training approach utilizing OBELICS, a vast dataset of interleaved image-text documents designed to enhance vision-language model performance.
Our experiments highlight significant performance improvements on visual question answering tasks due to interleaved image-text documents, revealing their pivotal role in optimizing language model capabilities.
