How to Use DeepSeek AI?

DeepSeek AI offers multiple integration methods depending on your needs, ranging from web-based chat to advanced API implementations. Here's how to use its capabilities effectively:

Web-Based Chat Interface

• Visit DeepSeek AI's official
• Sign up/login using email or third-party credentials.
• Access the chat interface with two key features:
  DeepThink R1 for complex reasoning
  Web search integration for real-time data.

Local Installation via Ollama

For offline use with privacy-focused operation:

# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Download model (8b version for average hardware)
ollama run deepseek-r1:8b

After installation, interact directly through your terminal.

API Integration

DeepSeek offers OpenAI-compatible API endpoints:

1. Get API key from DeepSeek Platform.
2. Configure using OpenAI SDK:

from openai import OpenAI
client = OpenAI(api_key="YOUR_KEY", base_url="https://api.deepseek.com")

response = client.chat.completions.create(
    model="deepseek-chat",  # or "deepseek-reasoner"
    messages=[{"role": "user", "content": "Your query"}]
)
print(response.choices[0].message.content)

Supports both streaming and non-streaming responses

Specialized Model Usage

DeepSeek offers domain-specific variants:

• Coding Assistance: Use deepseek-reasoner model.
• Math Solutions: Implement via API with math-specific prompts.
• Vision-Language Tasks: Access DeepSeek-VL through multimodal API endpoints.

Alternative Integration via OpenRouter

When direct API access is unavailable:

const openai = new OpenAI({
  apiKey: 'OPENROUTER_KEY',
  baseURL: "https://openrouter.ai/api/v1"
});

const result = await openai.chat.completions.create({
  model: 'deepseek/deepseek-r1',
  messages: [{role: "user", content: "Query"}]
});

Offers free tier access to basic capabilities.

For structured JSON outputs, add response_format: { type: "json_object" } to API calls with explicit formatting instructions in prompts. The system supports both cloud-based and self-hosted deployments.
