大型语言模型（LLM）通过利用思想链（CoT）提示生成中间推理链作为推断答案的基本原理，在复杂推理方面表现出令人印象深刻的性能。然而，现有的CoT研究集中于语言模态。我们提出了多模式CoT，它将语言（文本）和视觉（图像）模式结合到一个两阶段框架中，该框架将理论基础生成和答案推理分开。通过这种方式，答案推理可以更好地利用基于多模态信息的推理。使用多模态CoT，我们的模型在10亿个参数下的性能在ScienceQA基准上比之前的最先进LLM（GPT-3.5）高出16个百分点（75.17%->91.68%的准确度），甚至超过了人类性能。代码可在以下网址公开获取https://github.com/amazon-science/mm-cot.
Large language models (LLMs) have shown impressive performance on complex reasoning by leveraging chain-of-thought (CoT) prompting to generate intermediate reasoning chains as the rationale to infer the answer. However, existing CoT studies have focused on the language modality. We propose Multimodal-CoT that incorporates language (text) and vision (images) modalities into a two-stage framework that separates rationale generation and answer inference. In this way, answer inference can leverage better generated rationales that are based on multimodal information. With Multimodal-CoT, our model under 1 billion parameters outperforms the previous state-of-the-art LLM (GPT-3.5) by 16 percentage points (75.17%->91.68% accuracy) on the ScienceQA benchmark and even surpasses human performance.
