Executive Summary (执行摘要)

DeepSeek-V3.1 represents a significant advancement in large language model architecture, introducing a novel hybrid inference system that combines thinking and non-thinking modes within a single model framework. According to industry reports from Hugging Face and DeepSeek's official documentation, this release marks the company's strategic move toward the agent era, with substantial improvements in reasoning efficiency, tool utilization capabilities, and API infrastructure.

DeepSeek-V3.1代表了大型语言模型架构的重大进步,引入了新颖的混合推理系统,在单一模型框架内结合了思考和非思考模式。根据Hugging Face的行业报告和DeepSeek官方文档,此次发布标志着该公司向智能体时代的战略迈进,在推理效率、工具利用能力和API基础设施方面实现了显著改进。

Hybrid Inference Architecture (混合推理架构)

Think & Non-Think Modes (思考与非思考模式)

The core innovation of DeepSeek-V3.1 lies in its dual-mode inference system. The model operates in two distinct modes:

  1. Thinking Mode (思考模式): This mode employs extended reasoning processes, allowing the model to engage in multi-step problem-solving and complex analytical tasks. According to benchmark results, DeepSeek-V3.1-Think achieves answers in significantly less time compared to its predecessor, DeepSeek-R1-0528.

  2. Non-Thinking Mode (非思考模式): Designed for straightforward queries and rapid responses, this mode provides immediate answers without extended reasoning overhead.

DeepSeek-V3.1的核心创新在于其双模式推理系统。该模型以两种不同的模式运行:

  1. 思考模式:此模式采用扩展推理过程,允许模型进行多步骤问题解决和复杂分析任务。根据基准测试结果,与之前的DeepSeek-R1-0528相比,DeepSeek-V3.1-Think在显著更短的时间内获得答案。

  2. 非思考模式:专为直接查询和快速响应设计,此模式无需扩展推理开销即可提供即时答案。

Implementation and Access (实现与访问)

Users can toggle between these modes via the "DeepThink" button on the chat interface at https://chat.deepseek.com/. This implementation demonstrates DeepSeek's commitment to providing flexible inference options tailored to different use cases.

用户可以通过聊天界面https://chat.deepseek.com/上的"DeepThink"按钮在这些模式之间切换。此实现展示了DeepSeek致力于提供针对不同用例量身定制的灵活推理选项。

API Infrastructure Updates (API基础设施更新)

Endpoint Configuration (端点配置)

DeepSeek has restructured its API endpoints to align with the new hybrid architecture:

  1. deepseek-chat → Non-thinking mode (非思考模式)
  2. deepseek-reasoner → Thinking mode (思考模式)

Both endpoints support 128K context windows, enabling handling of extensive documents and complex conversations.

DeepSeek已重组其API端点以与新的混合架构保持一致:

  1. deepseek-chat非思考模式
  2. deepseek-reasoner思考模式

两个端点都支持128K上下文窗口,能够处理大量文档和复杂对话。

Compatibility and Features (兼容性与功能)

The API now supports Anthropic API format, enhancing interoperability with existing AI infrastructure. Additionally, Strict Function Calling is available in Beta API, providing more reliable tool integration capabilities for agent applications.
