The Cost Revolution

DeepSeek V3 changed the AI pricing:

Model	Input Cost	Output Cost	Price Ratio
DeepSeek V3	$0.008/M	$0.032/M	1x (baseline)
GPT-4o-mini	$0.15/M	$0.60/M	19x
GPT-4o	$2.50/M	$10.00/M	312x
Claude 3.5 Sonnet	$3.00/M	$15.00/M	375x

At $0.008/M, DeepSeek V3 enables use cases that were previously economically impossible.

Implementation Guide

Simple API Call

import openai

client = openai.OpenAI(
    api_key="your-deepseek-key",
    base_url="https://api.deepseek.com"
)

response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "What is the capital of France?"}
    ]
)

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

Cost Tracking

def estimate_cost(model: str, input_tokens: int, output_tokens: int) -> float:
    pricing = {
        "deepseek-chat": (0.008, 0.032),  # Input, Output per M
        "gpt-4o": (2.50, 10.00),
    }
    if model not in pricing:
        return 0.0

    input_price, output_price = pricing[model]
    return (input_tokens / 1_000_000 * input_price) + \
           (output_tokens / 1_000_000 * output_price)
