DeepSeek-V3.1-Terminus Release Notes

DeepSeek-V3.1-Terminus is an updated version of the DeepSeek-V3.1 model, designed to improve output stability and reliability. This update focuses on resolving language mixing issues and enhancing the specific capabilities of agentic workflows.

Language Consistency and Output Stability

DeepSeek-V3.1-Terminus reduces the frequency of mixed Chinese and English (CN/EN) outputs and eliminates the occurrence of random characters in generated text. These improvements lead to more stable and reliable outputs across benchmarks compared to the previous V3.1 version.

Agentic Performance Enhancements

The model update includes specific upgrades to agent performance, specifically improving the capabilities of the Code Agent and the Search Agent. These enhancements allow for more effective execution of tasks within agent-based frameworks.

Availability and Open Source

DeepSeek-V3.1-Terminus is available for use via the DeepSeek App, Web interface, and API. Additionally, the model weights have been open-sourced and are available for download on Hugging Face.
