## Introduction

This update maintains the model's original capabilities while addressing issues reported by users, including:

- Language consistency: Reducing instances of mixed Chinese-English text and occasional abnormal characters;
- Agent capabilities: Further optimizing the performance of the Code Agent and Search Agent.

**The template and tool-set of search agent have been updated, which is shown in `assets/search_tool_trajectory.html`.**

## How to Run Locally

The model structure of DeepSeek-V3.1-Terminus is the same as DeepSeek-V3. Please visit [DeepSeek-V3](https://github.com/deepseek-ai/DeepSeek-V3) repo for more information about running this model locally.

For the model's chat template other than search agent, please refer to the [DeepSeek-V3.1](https://huggingface.co/deepseek-ai/DeepSeek-V3.1) repo.

Here we also provide an updated inference demo code in the `inference` folder to help the community get started with running our model and understand the details of model architecture.

**NOTE: In the current model checkpoint, the parameters of `self_attn.o_proj` do not conform to the UE8M0 FP8 scale data format. This is a known issue and will be corrected in future model releases.**
