【Tech 24H】On the afternoon of August 21, DeepSeek officially launched DeepSeek-V3.1, calling it "the first step toward the era of Agents." The core innovation of V3.1 lies in its hybrid reasoning capability, allowing users to freely switch between thinking and non-thinking modes via a "Deep Think" button. Compared to DeepSeek-R1-0528, DeepSeek-V3.1-Think provides answers in a shorter time. Meanwhile, through Post-Training optimization, the new model shows significant improvements in tool usage and agent tasks, demonstrating stronger Agent capabilities.
