The 2026 AI API Pricing Guide: How to Save 90%
OpenAI GPT-4o charges $15 per million output tokens. DeepSeek V4 Flash β a comparable model β charges $0.25. That's 60x cheaper. Most developers are still paying GPT-4o prices because they don't know about alternatives or don't know how to switch. This guide fixes both problems.

client = OpenAI(
api_key="ga_your_key",
base_url="https://dashscope.aliyuncs.com/compatible-mode/v1" # Only change this
