How to use DeepSeek in ONLYOFFICE editors

DeepSeek AI is now integrated into ONLYOFFICE editors, enhancing productivity with advanced AI capabilities. In this article, we’ll explore how to use available DeepSeek models within ONLYOFFICE editors and how to connect them to the editors.

About DeepSeek models

DeepSeek is a family of AI models developed by DeepSeek Artificial Intelligence Co., Ltd., which specializes in natural language processing (NLP) and machine learning. The models are built on state-of-the-art transformer architecture and trained on vast datasets. They are designed to assist with various text-based tasks and offer different capabilities depending on the model used.

In the context of DeepSeek, these models help to assist users in office-related tasks, making them valuable tools for enhancing productivity and creativity.

DeepSeek models available in ONLYOFFICE

The DeepSeek models are accessible in ONLYOFFICE through the AI plugin. Below is a detailed description of each model available in the editors.

DeepSeek Chat

DeepSeek Chat is an AI model designed for interactive conversations, offering fluid and context-aware dialogue capabilities. It provides intelligent responses, making it suitable for customer support, brainstorming sessions, and real-time assistance in document creation.

Ideal for: Users who need an AI-powered chatbot for interactive discussions, quick research, and collaborative writing assistance.

Strengths: Natural conversational flow, contextual memory, and real-time adaptability.

DeepSeek Reasoner

DeepSeek Reasoner is specialized in logical inference, structured reasoning, and complex problem-solving. It is particularly useful for users who need deep analytical insights, mathematical reasoning, or structured decision support.

Ideal for: Data analysts, researchers, and professionals requiring rigorous logical processing and in-depth content analysis.

Strengths: Strong logical deduction, structured thought processes, and analytical depth.

You can also connect other DeepSeek model through the Together AI provider.

• Deepseek-ai/DeepSeek-R1: A versatile, general-purpose AI model optimized for everyday office tasks such as drafting emails, generating reports, and summarizing documents. Prioritizes consistent quality over niche specialization.

Ideal for users who need reliable AI assistance for everyday office tasks, such as drafting emails, generating reports, or summarizing documents.

Strengths: balanced performance, adaptability to various workflows.

Unlike Chat (focused on interactive dialogue) and Reasoner (logical/mathematical problem-solving), R1 emphasizes versatility over analytical depth.

• Deepseek-ai/DeepSeek-V3: Advanced AI for complex, context-rich tasks requiring detailed responses, such as high-quality content generation, nuanced language processing, or in-depth data insights.

Ideal for professionals who require high-quality content generation, detailed data insights, or sophisticated language processing.

Strengths: high accuracy, deep contextual understanding, ability to handle nuanced tasks.

While Chat thrives in real-time conversations and Reasoner – in structured logical reasoning, V3 focuses on depth and detail in static outputs.

Now, let’s take a closer look at how to customize each model to perform specific tasks with text and data.

Please note: for security reasons, no AI is connected to the editors by default. You choose yourself which provider/model to connect and use your own keys.
