+ ## Introduction
21
+
22
+ Vision-Language Models (VLMs) have shown promising capabilities in handling various multimodal tasks, yet they struggle in long-context scenarios, particularly in tasks involving videos, high-resolution images, or lengthy image-text documents.
23
+
24
+ To address this issue, we propose Variable Visual Position Encoding (V2PE), a novel positional encoding approach that employs variable and smaller increments for visual tokens.
25
+ Our experiments demonstrate the effectiveness of V2PE to enhances VLMs' ability to effectively understand and reason over long multimodal contexts. We further integrate V2PE with our augmented long-context multimodal datasets to finetune the open-source VLM, InternVL2-2B. The finetuned model achieves strong performance on both standard and long-context multimodal tasks.
26
+ Notably, when the sequence length of the training dataset is increased to 256K tokens, the model is capable of processing multimodal sequences up to 1M tokens, highlighting its potential for real-world long-context applications.
27
+
28
+ This repository contains the instruction-tuned V2PE-32K-InternVL-2B model and V2PE-256K-InternVL-2B model, which have 1.8B activated parameters (3B in total) and are trained on [V2PE-Data](https://huggingface.co/datasets/OpenGVLab/V2PE-Data).
29
+ It is built upon [InternVL2-2B](https://huggingface.co/OpenGVLab/InternVL2-2B). For more details, please refer to our [paper](https://arxiv.org/abs/2412.09616).
