Core Insights - DeepSeek has released two official models, DeepSeek-V3.2 and DeepSeek-V3.2-Speciale, with the former achieving performance levels comparable to GPT-5 and the latter winning gold medals in four international competitions [1][3]. Model Performance - DeepSeek-V3.2 has reached the highest level of tool invocation capabilities among current open-source models, significantly narrowing the gap with closed-source models [2]. - In various benchmark tests, DeepSeek-V3.2 achieved a 93.1% pass rate in AIME 2025, closely trailing GPT-5's 94.6% and Gemini-3.0-Pro's 95.0% [20]. Training Strategy - The model's significant improvement is attributed to a fundamental change in training strategy, moving from a simple "direct tool invocation" to a more sophisticated "thinking + tool invocation" mechanism [9][11]. - DeepSeek has constructed a new large-scale data synthesis pipeline, generating over 1,800 environments and 85,000 complex instructions specifically for reinforcement learning [12]. Architectural Innovations - The introduction of the DeepSeek Sparse Attention (DSA) mechanism has effectively addressed efficiency bottlenecks in traditional attention mechanisms, reducing complexity from O(L²) to O(Lk) while maintaining model performance [6][7]. - The model's architecture allows for better context management, retaining relevant reasoning content during tool-related messages, thus avoiding inefficient repeated reasoning [14]. Competitive Landscape - The release of DeepSeek-V3.2 signals a shift in the competitive landscape, indicating that the absolute technical monopoly of closed-source models is being challenged by open-source models gaining first-tier competitiveness [20][22]. - This development has three implications: lower costs and greater customization for developers, reduced reliance on overseas APIs for enterprises, and a shift in the industry focus from "who has the largest parameters" to "who has the strongest methods" [22].

Core Insights - The article discusses the limitations of current Vision-Language Models (VLMs) in accurately interpreting and executing spatial commands in robotics, emphasizing the need for precise geometric reasoning and tool integration [2][5]. Group 1: TIGeR Framework - The Tool-Integrated Geometric Reasoning (TIGeR) framework enhances VLMs by integrating tool usage and reinforcement learning to improve their ability to perform precise calculations in a three-dimensional space [2][6]. - TIGeR allows AI models to transition from qualitative perception to quantitative computation, addressing the core pain points of existing VLMs [2][7]. Group 2: Advantages of TIGeR - TIGeR provides precise localization by integrating depth information and camera parameters, enabling the accurate conversion of commands like "10 centimeters above" into three-dimensional coordinates [7]. - The framework supports multi-view unified reasoning, allowing information from various perspectives to be merged and reasoned within a consistent world coordinate system [7]. - The model's reasoning process is transparent, making it easier to debug and optimize by clearly showing the tools used, parameters input, and results obtained [7]. Group 3: Training Process - The training of TIGeR involves a two-phase process: first, supervised learning to teach basic tool usage and reasoning chains, followed by reinforcement learning to refine the model's tool usage skills through a hierarchical reward mechanism [8][10]. - The hierarchical reward mechanism evaluates not only the correctness of the final answer but also the accuracy of the process, including tool selection and parameter precision [8]. Group 4: Data Utilization - The TIGeR-300K dataset, consisting of 300,000 samples, was created to train the model in solving geometric problems, ensuring both accuracy and diversity in the tasks covered [10][13]. - The dataset construction involved template-based generation and large model rewriting to enhance generalization and flexibility, ensuring the model can handle complex real-world instructions [13]. Group 5: Performance Metrics - TIGeR outperforms other leading VLMs in spatial understanding benchmarks, achieving scores such as 93.85 in 2D-Rel and 96.33 in 3D-Depth [10][14]. - The model's performance in various spatial reasoning tasks demonstrates its capability to execute operations that require precise three-dimensional positioning, which other models struggle to achieve [16].
