How to Get Free AI Models on AIHubMix

Hunting for free AI models that don't ask for a credit card? AIHubMix has a catalog of around 50 models priced at $0.

That includes GLM-5.3, Ox Alpha (GLM-5.3 Flash), Gemini 3.7 Flash, Kimi K3, MiniMax M3, and several NVIDIA Nemotron models. One API key works across the whole catalog.

What You Need

• An email address you can open.

Tutorial

1. Open AIHubMix.
2. Sign up with your email. No credit card is required.
3. Create an API key.
4. Pick a free model and use its Base URL. The service works with OpenAI-compatible tools, so one key covers every model in the catalog.

Wrapping Up

You now have access to a free model catalog with a single API key. Pick a model, plug in its Base URL, and start building. If one model doesn't fit, switch to another without setting up a new key.
