Example

from openai import OpenAI

client = OpenAI(
    base_url="https://openapi.linkwo.ai/v1",
    api_key="YOUR_API_KEY"
)

response = client.chat.completions.create(
    model="deepseek/deepseek-v4-pro",
    messages=[
        {"role": "system", "content": "You are an expert Python developer."},
        {"role": "user", "content": "Implement a binary search tree with insert, search, and delete operations."}
    ],
    temperature=0.3
)

print(response.choices[0].message.content)

Best Practices

• Use temperature: 0.3 for coding and math tasks for more deterministic output
• Use temperature: 0.7 for creative writing and brainstorming
• Break complex tasks into steps for better results
• Leverage the 1M context for large codebases or long documents
