Xiaomi's MiMo is a large language model (LLM) family designed for multi-modal reasoning. It boasts enhanced capabilities in complex reasoning tasks involving text and images, surpassing existing open-source models in various benchmarks. The MiMo family comprises different sizes, offering flexibility for diverse applications. It's trained using a multi-modal instruction-following dataset and features chain-of-thought prompting for improved reasoning performance. Xiaomi aims to foster open research and collaboration by providing access to these models and their evaluations, contributing to the advancement of multi-modal AI.
The Xiaomi MiMo Reasoning Model project introduces a novel approach to multimodal reasoning, aiming to bridge the gap between perception and cognition. It achieves this by unifying various multimodal tasks, such as visual question answering (VQA), image captioning, and visual grounding, under a single, comprehensive framework. This framework leverages Large Language Models (LLMs) as the central reasoning engine, capitalizing on their inherent ability to understand and generate natural language. Crucially, the MiMo framework doesn't simply treat images as raw pixel data. Instead, it employs a sophisticated "perception-to-cognition" pipeline that transforms visual information into a structured, symbolic representation, making it more digestible for the LLM.
This structured representation is achieved through the use of pre-trained Visual Perception Models (VPMs). These models are responsible for extracting meaningful features from the image, such as object detections, attributes, and their spatial relationships. These extracted features are then converted into a series of discrete, symbolic elements that can be readily interpreted by the LLM. This symbolic representation, which can be considered a form of "visual language," allows the LLM to reason about the image content in a more abstract and logical manner, mirroring the way humans process visual information.
The project's developers emphasize the modularity and flexibility of the MiMo framework. Users can easily swap out different LLMs and VPMs depending on the specific task or dataset. This adaptability makes the MiMo model readily applicable to a wide array of multimodal scenarios. Furthermore, the developers provide comprehensive documentation and open-source code to encourage community involvement and further development of the model. The provided examples demonstrate the model's capabilities across diverse tasks, highlighting its potential to advance the field of multimodal AI and pave the way for more robust and generalizable multimodal reasoning systems. The project aims to move beyond simple pattern recognition towards true visual understanding, enabling AI systems to interpret and reason about complex visual scenes with greater accuracy and sophistication.
