What is Skywork R1V
Skywork R1V is Kunlun Wanwei's first open-source industrial multimodal chain-of-thought reasoning model, featuring powerful visual chain-of-thought reasoning capabilities. Skywork R1V can perform multi-step logical reasoning on visual inputs to solve complex visual tasks, such as visual logical reasoning, visual mathematical problems, scientific phenomenon analysis, and medical image diagnosis. The model performs excellently on multiple authoritative benchmarks, achieving high scores of 94.0 and 72.0 on the MATH-500 and AIME tests, respectively, significantly outperforming other mainstream models. The open-sourcing of Skywork R1V advances the development of multimodal reasoning models, supporting academic research and industrial application exploration.
Main Features of Skywork R1V
- Visual Chain-of-Thought Reasoning: Performs multi-step logical reasoning on visual inputs (such as images or videos), progressively analyzing and deriving answers to complex problems.
- Mathematical and Scientific Problem Solving: Recognizes and parses mathematical problems or scientific phenomena in images, providing step-by-step solutions combined with reasoning capabilities.
- Cross-Modal Understanding: Deeply integrates visual and textual information to achieve richer semantic understanding.
- Complex Visual Task Processing: Handles complex visual tasks, such as medical image diagnostic reasoning and artwork analysis.
Technical Principles of Skywork R1V
- Multimodal Transfer of Textual Reasoning Capabilities: Based on a Visual Projector, efficiently transfers textual reasoning capabilities to visual tasks without retraining the language model and visual encoder. Retains the model's strong capabilities in textual reasoning tasks while processing visual inputs.
- Multimodal Hybrid Training (Iterative SFT + GRPO): Combines Iterative Supervised Fine-Tuning (Iterative SFT) and Group Relative Policy Optimization (GRPO) reinforcement learning to align visual and textual representations in stages. Uses a combination of high-quality and high-difficulty data, iteratively training to enhance the model's performance in cross-modal tasks, achieving or surpassing existing leading models on visual reasoning benchmarks.
- Adaptive Length Chain-of-Thought Distillation: Introduces an adaptive reasoning chain length control mechanism based on visual-text complexity, dynamically optimizing the model's reasoning process. Combines multi-stage self-distillation strategies to prevent the model from "overthinking" and improve reasoning efficiency and quality.
- Three-Stage Training Method：
- Initial Alignment: Uses a lightweight visual adapter (MLP) to connect the visual encoder and language model, training on conventional multimodal data to initially align visual and language representations.
- Reasoning Capability Transfer: Connects the trained adapter with a strong reasoning language model to form a visual reasoning model, equipping the model with initial visual reasoning capabilities.
- Precise Alignment: Based on a hybrid optimization framework (Iterative SFT + GRPO), further precisely aligns visual and language modalities to enhance the model's multimodal reasoning capabilities.
