# Introduction

The Infinity-VL-2B model is a vision-language model (VLM) trained based on the [LLava-one-vision] (https://llava-vl.github.io/blog/2024-08-05-llava-onevision/) framework. The [Qwen2.5-1.5B-instruct](https://huggingface.co/Qwen/Qwen2.5-1.5B-Instruct) model is chose as the LLM, while [siglip-so400m-patch14-384](https://huggingface.co/google/siglip-so400m-patch14-384) is utilized as the vision tower.

The model was trained on our self-built Infinity-MM dataset, which contains approximately 40 million image-text pairs. This dataset is a combination of open-source data collected from the internet and synthetic instruction data generated using open-source VLM models.

We plan to open-source the Infinity-MM dataset, training scripts, and related resources in the near future. For more technical details, stay tuned for our upcoming technical report.

# Evaluation

We evaluated the model using the [VLMEvalKit] (GitHub - open-compass/VLMEvalKit: Open-source evaluation toolkit of large vision-language models (LV) tool. Whenever possible, we prioritized using the GPT-4 API for test sets that support API-based evaluation.

For comparison models, evaluations were conducted in a local environment, so the scores may differ slightly from those reported in papers or on the official VLMEvalKit leaderboard.

* Future training will incorporate multi-image and video data.
* We will open-source the Infinity-MM dataset and training code.
* A comprehensive technical report will be released.
