One API Key, Every Model: Unifying GLM, MiniMax and DeepSeek

Tired of managing a dozen API keys? Learn how a one-key gateway unifies GLM, MiniMax and DeepSeek behind a single OpenAI-compatible endpoint — and why it simplifies your stack.

Every team that builds on multiple models ends up with the same mess: a folder of API keys, per-provider SDK quirks, and retry logic copied three times with subtle differences. It works until it doesn't.

The clean alternative is a single OpenAI-compatible endpoint in front of every model. GLM for bilingual workloads, MiniMax for voice and long context, DeepSeek for cheap coding — all behind one key, switched by changing the model field.

The underrated benefit is operational, not just convenience. When every provider's errors are normalized on your side, your retry and fallback logic finally works. You stop getting 200 responses with truncated bodies that pretend to be successes.

Routing is where the savings come from. A fast small model handles classification and routing; the big model only runs the hard generation step. Per-task routing beats one model doing everything — cheaper and better.

If you're starting fresh, don't collect keys. Stand up one gateway, point every client at it, and add models as you need them. Your future self will thank you at 3am.
