We are so happy to announce our new model Aion 1.0 today!

Our team at AI Frontiers Lab at Microsoft Research had been cooking hard on this for quite a while.

Aion 1.0 is 14B model that can run locally with reasoning + tool calling capabilities. You can choose whatever agentic harness you like or make your own. Calls to the model never leaves your device and no one charges you for any tokens you use πŸ₯³.
