DeepSeek-V3.1 Both deepseek-chat and deepseek-reasoner have been upgraded to DeepSeek-V3.1. deepseek-chat corresponds to DeepSeek-V3.1's non-thinking mode , while deepseek-reasoner corresponds to its thinking mode . Key updates in DeepSeek-V3.1: Hybrid reasoning architecture : A single model supports both thinking mode and non-thinking mode Improved reasoning efficiency : Compared to DeepSeek-R1-0528, DeepSeek-V3.1-Think provides answers in significantly less time Enhanced agent capabilities : With post-training optimization, the new model achieves major improvements in tool usage and intelligent agent tasks SWE-bench Verified: 66.0 SWE-bench Multilingual: 54.5 Terminal-bench: 31.3
DeepSeek-V3.1-Terminus Both deepseek-chat and deepseek-reasoner have been upgraded to DeepSeek-V3.1-Terminus. deepseek-chat corresponds to DeepSeek-V3.1-Terminus's non-thinking mode , while deepseek-reasoner corresponds to its thinking mode . This update maintains the model's original capabilities while addressing issues reported by users, including: Language consistency: Reduced occurrences of Chinese-English mixing and occasional abnormal characters; Agent capabilities: Further optimized the performance of the Code Agent and Search Agent.
