According to DeepSeek (@deepseek_ai), the new DeepSeek-V3.1 AI model introduces a hybrid inference system, allowing both 'Think' and 'Non-Think' modes in a single model. This upgrade enables faster reasoning, as DeepSeek-V3.1-Think significantly outpaces the previous DeepSeek-R1-0528 in delivering answers. Additionally, post-training enhancements empower the model with stronger agent skills, improving its ability to utilize tools and execute complex tasks autonomously. These advancements signal a move toward more capable AI agents, opening up business opportunities in process automation, intelligent workflow management, and advanced digital assistants (Source: DeepSeek on Twitter, August 21, 2025).
