Core Insights - DeepSeek has officially released DeepSeek-V3.1, introducing a hybrid reasoning architecture that allows users to switch between "Deep Thinking" mode and "Non-Thinking" mode for enhanced interaction [2][3]. Group 1: Hybrid Reasoning Architecture - The "Deep Thinking" mode (DeepSeek-Reasoner) is designed for tasks requiring deep reasoning, such as mathematical calculations and complex logic analysis, providing higher reasoning efficiency [3]. - The "Non-Thinking" mode (DeepSeek-Chat) is tailored for everyday conversations and information queries, offering quicker responses [4]. - Users can easily switch modes via a "Deep Thinking" button on the official app and web interface, enhancing the user experience [5]. Group 2: Enhanced Agent Capabilities - DeepSeek-V3.1 has significantly improved tool usage and agent task performance through Post-Training optimization, resulting in fewer required iterations and higher efficiency in code repair and command line tasks [6]. - Benchmark results show that DeepSeek-V3.1 outperforms its predecessor, DeepSeek-R1-0528, in various tasks, including SWE-bench and Terminal-Bench, with scores of 66.0 and 31.3 respectively [7][8]. Group 3: Efficiency Improvements - The new version employs a thought chain compression training method, reducing output tokens by 20%-50% while maintaining performance levels comparable to DeepSeek-R1-0528, leading to faster response times and lower API call costs [9]. Group 4: API Upgrades and Model Availability - The DeepSeek API has been upgraded to support a context length of 128K, facilitating easier handling of long documents [10][12]. - The base and post-training models of DeepSeek-V3.1 are now open-sourced on platforms like Hugging Face and ModelScope, with a price adjustment for the API set to take effect on September 6, 2025 [11].

Core Viewpoint - DeepSeek has officially released version V3.1, featuring significant upgrades in reasoning architecture, efficiency, and agent capabilities [3][4]. Group 1: Key Features of DeepSeek-V3.1 - The new hybrid reasoning architecture allows the model to support both thinking and non-thinking modes simultaneously [3]. - Enhanced thinking efficiency enables DeepSeek-V3.1-Think to provide answers in a shorter time compared to its predecessor, DeepSeek-R1-0528 [3]. - Improved agent capabilities through post-training optimization have led to better performance in tool usage and intelligent tasks [3]. Group 2: API and Pricing Changes - The official app and web model have been upgraded to DeepSeek-V3.1, allowing users to switch between thinking and non-thinking modes via a "deep thinking" button [3]. - The DeepSeek API has also been upgraded, with deepseek-chat corresponding to non-thinking mode and deepseek-reasoner to thinking mode, expanding context to 128K [3]. - Starting from September 6, 2025, the pricing for API calls will be adjusted, with the cancellation of night-time discounts [4][6].
