Hybrid thinking mode: One model supports both thinking mode and non-thinking mode by changing the chat template.

Smarter tool calling: Through post-training optimization, the model’s performance in tool usage and agent tasks has significantly improved.

Higher thinking efficiency: DeepSeek-V3.1-Think achieves comparable answer quality to DeepSeek-R1-0528, while responding more quickly.
