Key Features and Characteristics

DeepSeek offers a comprehensive suite of features that cater to diverse user needs:

Dual-Model Architecture

The platform operates with two specialized models: DeepSeek-V3 for general tasks and DeepSeek-R1 for complex reasoning. The V3 model excels in rapid text generation and multimodal information processing, making it ideal for administrative tasks, content creation, and coding assistance. The R1 model specializes in logical reasoning, mathematical problem-solving, and detailed analytical tasks, providing step-by-step reasoning processes that enhance transparency and understanding.

Advanced Technical Capabilities

DeepSeek incorporates cutting-edge technologies including Mixture of Experts (MoE) architecture and Multi-Head Latent Attention (MLA) mechanisms. These innovations enable the model to dynamically allocate computational resources based on task complexity, significantly improving efficiency. The MLA technology optimizes information processing by reducing memory usage when handling lengthy documents while maintaining accuracy.

Multilingual Support and Specialization

While supporting 72 languages, DeepSeek demonstrates exceptional proficiency in Chinese language processing. It outperforms many leading models in Chinese comprehension and generation tasks, particularly valuable for academic and professional applications requiring nuanced language understanding. The model’s large context window enables it to process and maintain coherence across extensive conversations and complex documents.

Cost-Effectiveness and Accessibility

One of DeepSeek’s most significant advantages is its affordability. The API pricing structure offers unprecedented value at ¥0.5-2 per million input tokens and ¥8 per million output tokens, representing approximately 3% of competing models’ costs. This pricing strategy dramatically lowers the barrier to entry for developers and enterprises seeking to integrate advanced AI capabilities.

How to Use DeepSeek: Complete Guide

Access Methods

Users can access DeepSeek through multiple channels:

• Web Platform: Visit chat.deepseek.com for direct browser access
• Mobile Applications: Available on iOS App Store and Android Google Play
• API Integration: Developers can integrate DeepSeek capabilities via platform.deepseek.com
• Third-Party Platforms: Integrated into national supercomputing platforms and various cloud services

Effective Usage Strategies

To maximize DeepSeek’s potential, users should employ structured communication approaches:

Four-Step Questioning Method

This method involves providing:

1. Background context​ to establish understanding
2. Specific tasks​ to define objectives clearly
3. Requirements and constraints​ to guide output quality
4. Supplementary details​ to enhance relevance

For example, instead of asking vaguely for a “marketing plan,” specify: “As a new café owner near a university campus, I need a promotional plan targeting students with a ¥10,000 budget, focusing on premium coffee offerings.”

Task Decomposition Strategy

Break complex projects into manageable steps. When writing an article, first generate an outline, then develop sections sequentially, followed by refinement and fact-checking phases. This approach ensures coherent and comprehensive results.

Iterative Optimization

DeepSeek responds well to progressive refinement. Provide specific feedback on previous outputs to guide improvements. For instance, if an initial marketing plan lacks student focus, request enhancements targeting academic schedules and campus activities.
