The Problem I was paying for 5+ different AI subscriptions: OpenAI, Anthropic, Google, etc. Each with separate API keys, billing dashboards, and SDK quirks. When DeepSeek-V3 dropped at ~$0.28 per million output tokens (vs GPT-4o at $10), I wanted to switch — but the friction of changing SDKs across multiple projects was a pain. So I built TokenHub — an OpenAI-compatible gateway that routes to 40+ AI models with a single API key. How It Works It's a drop-in replacement for the OpenAI SDK. Just change base_url and api_key : from openai import OpenAI client = OpenAI ( api_key = " your-tokenhub-key " , base_url = " https://jiatoken.com/v1 " ) # Use any of 40+ models — DeepSeek, MiniMax, Claude, GPT, Gemini, Llama, etc. response = client . chat . completions . create ( model = " deepseek-v3 " , messages = [{ " role " : " user " , " content " : " Explain async/await in Python " }] ) print ( response . choices [ 0 ]. message . content ) Enter fullscreen mode Exit fullscreen mode That's it.…
