How to Handle DeepSeek V4 Peak Hour Pricing with Model Routing

Handling DeepSeek V4 Peak Hour Pricing

DeepSeek V4 official release is July 15, 2026 with peak hour pricing (9:00-12:00, 14:00-18:00 Beijing time) at 2x normal rates.

The solution is model routing - automatically send simple tasks to cheap models like GLM-4-Flash ($0.05/M) and reserve expensive ones for complex tasks.

Python Implementation

from openai import OpenAI
client = OpenAI(base_url="https://api.tunanapi.com/v1", api_key="your-key")

def route_task(prompt):
    keywords_simple = ["is", "yes", "no", "count"]
    keywords_complex = ["analyze", "debug", "explain"]

    if any(k in prompt.lower() for k in keywords_simple):
        model = "glm-4-flash"
    elif any(k in prompt.lower() for k in keywords_complex):
        model = "deepseek-v4-pro"
    else:
        model = "deepseek-v4-flash"

    return client.chat.completions.create(model=model, messages=[{"role": "user", "content": prompt}])
