-**RLAIF-V-7B** is a variant of LLaVA 1.5 7B with greatly enhanced trustworthiness. The model is trained by a novel framework, **RLAIF-V**, that aligns MLLMs in a **fully open-source paradigm for super GPT-4V trustworthiness**. RLAIF-V maximally exploits the [open-source feedback](https://huggingface.co/datasets/openbmb/RLAIF-V-Dataset) from two key perspectives, including **high-quality feedback data** and an **online feedback learning algorithm**.
