Chinese startup DeepSeek has unveiled its latest AI model, DeepSeek-V3.1, marking a significant upgrade in performance and architecture. The model introduces a hybrid inference structure, enabling users to switch between reasoning (“think”) and non-reasoning modes for greater efficiency and adaptability across tasks.
With faster processing speeds and improved agent capabilities, V3.1 positions itself as a competitive open-weight alternative in the global AI race.
DeepSeek also added a “deep thinking” toggle for app and web users, giving flexibility in response generation. Additionally, the company announced API pricing changes effective September 6, 2025.
