Uni-CoT: Towards Unified Chain-of-Thought Reasoning Across Text and Vision
Project Page | Paper | GitHub
Uni-CoT is a unified Chain-of-Thought (CoT) framework designed to enable coherent and grounded multimodal reasoning within a single model. It introduces a two-level reasoning paradigm (Macro-Level and Micro-Level CoT) to handle high-level planning and subtask execution across text and vision.
Dataset Summary
This repository provides data for building unified interleaved reasoning mechanisms as implemented in Uni-CoT. The project has released two primary datasets:
- UniCoT-Self-Reflection-6K: Data focused on the Micro-Level CoT self-reflection mechanism to ensure stable and high-quality results in subtask execution.
- UniCoT-Breakdown-3K: Data focused on the breakdown mechanism for structured task planning and sequential decomposition.
These datasets leverage a structured training paradigm that combines interleaved image-text supervision with multi-task objectives, allowing models to perform scalable and coherent multi-modal reasoning.
